As the usage of smartphones has increased among customers, application development has been growing at a rapid pace. In terms of global market share, Android tops the list. The next in line is Apple’s iOS and Windows, respectively. As a mobile app developer or a business owner, it gets confusing at times to choose the best platform for developing an application, other than its native platform. 

Learning a new language, knowing the API’s, etc. is not only tedious but also a time-taking process. In that case, Xamarin will come to your rescue. With Xamarin, you can build cross-platform mobile applications to facilitate similar functions like platform native apps. You can directly develop apps for Android, iOS, and Windows apps from the Visual Studio itself.

Benefits of Xamarin Over Other Platforms

We bring you some of the profound benefits of Xamarin has over other technologies –

Reusable Code

All of the Xamarin apps can be entirely built in Visual Studio. Xamarin takes the help of C# integrated with a.Net framework for creating apps for a mobile platform. Thus, you get to reuse about 96% of source code leading to a speedy production of the application. cycle.

As Good as Native Platform

The performance of Xamarin also meets the standards of native application development. With Xamarin, a cross-platform app can still get classified as a native app. The performance metrics can be easily compared with those of Java for Android and even Objective- C, or Swift to create a native app for iOS.

 Visual Studio provides a total option to build, test, and track the performance of an app.

Native User Experience

With Xamarin, you can create a superb experience with the help of platform-specific UI elements. A lot of simple apps for iOS, Android, and Windows get designed with the help of Xamarin. The use of Xamarin with the Forms tool brings about a significant increase in the pace of application development. With such a speedy process of development, it becomes a fantastic option for business-oriented projects.

Hardware Support

Xamarin provides your solution with native-level app functions. The tool eliminates every hardware compatibility issue through plugins and particular API’s. This allows Xamarin to work with conventional device functionality across all platforms.

With access to platform specific API’s, Xamarin provides the function of linking native libraries. It gives a better degree of customization and a native-level functionality with just a little added cost.

Strong Corporate Support

When Microsoft acquired Xamarin in the year 2016, the licensing policies underwent quite a lot of significant changes. Xamarin SDK, with runtime, command line tools, and libraries have all become open sourced and available as per MIT license through Visual Studio.

The cost of license tends to be a significant barrier, and by eliminating this, Microsoft opened up the doors to further development of this platform

Ease in Maintenance

Because of its cross-platform ability, Xamarin makes maintenance and providing updates easier. Developers can deploy the changes or updates to the source file itself. These updates then automatically get applied to both the iOS and Android applications.

It is important to note that this only works for the applications running on Xamarin. In short, with Xamarin, you save a lot of time and money spent on keeping your apps up to date.

Conclusion

Smartphone applications have become a part of peoples’ daily life. Security isn’t the first thing we think of while purchasing an application, but it is a matter of concern. iOS users stand at an advantage here. Though Android also has the required security protocols in place, but it is iOS that has the upper hand in terms of security. iOS applications mitigate the risk of data leakage and security harms. The apps developed in iOS are much more secure than the Android application. 

 

So are you thinking, what makes iOS applications so secure?

 

Here are the top features that make iOS applications so secure – 

 

Data Protection API: All versions of iOS, after iOS 4, have an inbuilt security feature of Data Protection. The feature allows the iOS app to encrypt and decrypt its files automatically. This feature is by default activated in iOS apps, but you can configure it as per your need. 

 

KeyChain API: Keychain is a hardware-oriented secure data storage that stores small data such as passwords, certificates, and credentials. The iOS has its own dedicated space in the Keychain that does not allow access to other apps. This way, the system provides you the highest level of security.

 

CloudKit: The CloudKit allows you to store data in Apple’s iCloud by using your Apple ID. It enables the security feature by which your app and the server’s commutation can be done using Apple’s client-side CloudKit framework. 

 

Verifying Signature: iOS applications use verified signatures. Before sending a message, you need a private or public key pair. This signature is then sent together with the receiver’s actual data, using the public key to validate the signature.

 

Encrypted Data Transfer: The airdrop got introduced with IOS 7. It allows you to share files with just a tap. The files are encrypted, but this service lets you be visible only to your contacts by default. If you require, you can change the settings. 

 

Highly Secure Authentication: iOS is known for its authentication feature. Face Recognition, fingerprint authentication, and eye recognition are some of the features that iOS bought it first in the industry. 

 

HTTPs: iOS launched a new feature called App Transport Security (ATS) that improves the security of the connecting network by blocking HTTP connections. Otherwise, HTTP connections are not that firm.  

 

Why iOS?

Nowadays, many entrepreneurs and businesses are investing in iOS app development for a secure and reliable mobile application. The primary reason being the security features. But there are much more benefits of the iPhone Operating System. With every new launch of iOS versions and updates, its security features are becoming more sturdy. Leading the way with innovation, iOS focuses to make data encrypt and firm. Though the iOS devices come with high prices than other operating systems, their users know its value and are ready to pay for it. 

Creating a reliable, secure, and powerful iOS is not an easy process. Data security is the highest priority & iOS always tries to perform in terms of safety.

So, you are on your way to having a dedicated mobile application for your business? A customized mobile app will addon to your brand’s value and give credibility. But there are some factors you must consider while developing your app. The points mentioned below are often ignored, but they are crucial for the success of your application. GoodWorkLabs, a renowned app development company in Bangalore, follows these to develop next-gen applications with all the vital factors in mind. Read the tips below to understand –

 

High-Speed Navigation 

 

You must make sure that your mobile application isn’t slow to navigate or reload. Rather, it should be rapid and responsive with a high response time. It is a crucial factor on which the overall success of your application will depend, as a slow application that makes people wait around, resonates with none. 

 

Hassle-Free Sign Up

You have a limited time to make any user stick to your application.  Make every moment count! Do not let the user struggle to register, sign up, or fill out forms. Try to make the sign-in experience short and crisp & eliminate every possible click from the design to make it quick and easy. Ask for as little information as possible(keeping in mind the security concerns).

 

Alternate Logins

Along with the usual login/sign-up process, you should also allow users to log in through their social media accounts such as Facebook Connect or their email accounts. Along with it, also dont forget to give a hassle-free way to retrieve their user name/password.  

 

Feedback system

Your new application must take feedback from its actual users to further enhance and debug the whole application. Tell your app development company to add a way in the app, to take feedback. It will provide you with suggestions on areas to improve and make the app more user-friendly.  Even users will appreciate that you consider their feedback. 

 

Easy Usability

The mobile application should feature an user interface that focuses more on usability. You can follow the usual application flows of other similar widely-used apps to get an idea for your own mobile app development. A neat and simple interface will speak for itself!

 

Simple UI/UX

Adding lots of features to your application will not make it attractive rather confuse the users. Let the few basic things be clear for users to do what they want in less time than searching for features and getting lost in them. Delivering a richer experience compactly and effectively, with simple UI/UX, is the key here!

 

Similar web & mobile version

If you are converting a web-based system to a mobile app, or vice-versa, make sure not to omit any features. The web-based or mobile application should be completely similar in all aspects. What’s even better? Connect with GoodWorkLabs, the Google certified agency in Bangalore that provides Flutter application development services. Flutter uses the same codebase for both web and mobile-based applications, hence the chances of errors are omitted.

   

Include analytics

One key element that your app development partner should include in your mobile app is analytics. Using the data gathered from analytics, you will be able to track and identify users’ responses, experiences, and actions. This will further help to make better decisions and encourage better updates.  

 

Include Offline capabilities

Adding something in the application that works even without the internet is not a bad idea! It can be a jigsaw puzzle, or a simple game, or pieces of information. Check with your app development agency, what can be added to make the app more interactive even without any signal. 

 

GoodWorkLabs, your App Development Partner

Best Automation Testing Tools

Automation testing means evaluating the software programs and running execution of test cases automatically, thus producing test results without any human intervention. It is one step ahead of man-made testing. It saves physical efforts and helps in saving time up to a great extent and it also leaves no or very less scope for errors in testing.

Once set for running, automated tests can be run any number of times to test the same application, thus minimizing redundant physical work of humans.

In this post, we have outlined 6 automation software testing tools that can greatly increase your productivity.

 The most popular automation testing tools are:

1. Selenium

Selenium is an automation source tool which is used for automating the tests for business carried out on web browsers. Since Selenium is open-source and is free, there is no licensing cost involved, which is a major advantage over other testing tools. 

 Other reasons behind Selenium’s ever-growing popularity are:

1. In any programming language, its script can be written: Java, Python, C#, PHP, Ruby, Perl &.Net.
2. Tests can be solved on any of these OS: Windows, Mac or Linux.
3. Tests can be solved using any browser: Mozilla Firefox, Internet Explorer, Google Chrome, Safari or Opera.
4. It can be used to test a web application.
5. There is no reporting facility in selenium but we can overcome this problem by integrating it with frameworks like TestNG or JUnit.

2. Test Complete

Test Complete is a functional automated testing platform developed by Smart Bear. The software completely gives testers the ability to create automated tests. It runs on Microsoft Windows, Web, Android (Operating system), and iOS applications. Tests can be recorded, solved and manually created with keyword-driven operations and used for automated playback and error logging.

Test Complete contains three modules:

1. Desktop
2. Web
3. Mobile

Each of the above modules contains functionality for creating automated tests on that specialized platform. Test Complete is used for testing different applications, different types of computer tools including Web, Windows, Android, iOS, WPF, HTML5, Flash, Flex, Silverlight, .NET, VCL and JAVA. It performs functional testing and back-end testing like database testing.

It helps in creating, executing and making automated text across the desktop, web, and mobile applications easy, speedy, and cost-effective.  Some of the key features of it are:-

1. Industry-leading object recognition.
2. Support of 7 different scripting languages.
3. The ability to record robust-automated tests without scripting knowledge.

 

3. QMetry Automation Studio

QMetry Automation Studio leverages an open-source test automation framework like Selenium and Opium to bring structure, efficiency, and reliability to your automated testing efforts. This studio enables advanced automation with coded automation and allows manual testers to transition into automated testing easily with script-less automation.

The management supports typical testing scenarios like mobile barcode scanning, touch ID, location spoofing and many more. As a result, QMetry Automation Studio is well-suited for micro-services type application with various complex components for automated testing.

QMetry is tailor-made for agile testing and develops teams to deliver better quality software faster, with confidence. It simplifies the creation, maintenance, and management of test libraries and seamlessly integrates with major platforms.

 

 

4. Testim.io

Testim.io leverages machine learning for the authoring, execution, and maintenance of automated test business cases. They use dynamic locators and learn with every execution. The result is very fast authoring and through constant tests, the platform learns and eliminates the need to continually maintain tests with every code change.

Testis, a Heavy bit portfolio company, has dual offices in San Francisco and Israel (R&D) and is backed by Spider Capital (A purify, Pager Duty), Foundation Capital and other U.S. based investors.

Testim.io effectively removes the falseness of the automation suites and is committed to helping engineering teams in making application testing autonomous and integrative to their agile development cycle.

Testis’ self-learning tests adapt to code changes, eliminating a big portion of maintenance overhead. Organizations which are using it spend more of their efforts on developing new functionality as opposed to testing, without compromising quality.

 



5. Cypress

Cypress tests are used to test anything that runs in a browser. The Cypress test runner is formed to handle modern JavaScript frameworks as well. We have hundreds of projects using the latest frameworks like React, Angular, etc. It also works equally well on server-applied applications. It records test-runs in continuous relation so that you can understand failures and share results with your team.

 

Cypress has one of the best design principles which include packaging and bundling everything together to make the entire end-to-end testing experience really pleasant and simple for developers. It is open source with paid features. This test runner is everything that we can do on our local computers. It takes a different approach since it’s actually executed in the same run loop as our applications. This will let you natively access every single object without having to deal with object serialization or over-the-wire products.

 

6. HP Quality Center Enterprise (QC)

Integrated quality management software is one which helps you to standardize testing, engineer for enhancement, and fixes problems to improve quality. It delivers applications fast with confidence and courage. It provides a comprehensive, unified, and extensible software quality platform.

You can implement your entire quality and logistic testing and establish consistent, repeatable processes for managing all aspects of software quality. This extraordinary, unified platform helps you possess a complete IT quality management infrastructure, establish consistent, repeatable processes and applies the best practices for all business applications.

Assets sharing and reusability allowed HP quality center enterprise to deliver bug-free and reliable applications. It helps to maintain consistent QA procedures across the application lifecycle by standardizing testing. Thus, the integrated approach of HP quality center helps to monitor performance, fix defects, and reduce making costs.

Thus these are some very powerful and reliable automation testing software tools that you can use for your business applications. Aim for shorter development cycles with automated testing.

IBM Bluemix – A Mix Of Amazing Things

IBM Bluemix is a cloud platform as a Service based on open standards such as Cloudfoundry, Docker & Openstack. Bluemix comes in 3 deployment models – Public , Dedicated & Local. Bluemix Public is a multi-tenant where as Dedicated & Local are single tenant environments. Dedicated resides on IBMs Softlayer datacenter and Local resides behind your firewall. You have choice of deployment models which may not be available with Amazon or google.

Many enterprises have hybrid cloud requirements so Bluemix and other IBM Cloud offerings would be able to offer end to end solutions.

Watson based cognitive services, integrated DevOps , range of mobile backend services , database & analytics services makes IBM Bluemix a very rich platform. There are over 150+ services on the Bluemix platform.

Its very difficult to compare pricing as most of the public PaaS offerings are never easy to compare. For example, the cost of Bluemix Services are based on API calls (& storage) and there are no charges for data traffic. Many vendors may charge you for the data going out of their datacenter.

Recently IoT became has become a big tech to invest in. It is far easy to use BlueMix with Arduino or Raspberry Pi than anything else. Number of projects on Github, documentation, community help on Stackoverflow are enormous.

Advantages Of IBM Bluemix

 

1. Simplicity and speed: By focusing on the DevOps model, Bluemix can reduce the downtime of redeploying applications. Continuous delivery is one way this can be provided. The integrated environment provided by Bluemix allows developers to automatically deliver code without the hassle of building and debugging installation scripts. This reduces the time needed to manage code delivery and puts it in the hands of the testers and user community faster. The application can be deployed to multiple spaces which allow segregation of environments for development, testing and production. Automatically delivering code keeps developers focused on coding, not installation.

2. Agility: Bluemix allows developers to focus on delivering business value, rather than on maintaining the development environment, by scaling environments elastically based on business demand. Instead of manually deploying workloads, Bluemix will automatically redeploy workloads to other virtual machines (VMs) if there is an outage. To provide continuous availability, Bluemix abstracts the underlying architecture and keeps the manageability of services and applications at an easily understood level. Users are able to stop or start applications and define how much memory is associated with each application while Bluemix manages the rest.

3. Tools: With Bluemix, developers have the freedom to choose the development tools that work best for them. Developers don’t always want to work with the same tool sets and Bluemix provides several options, including the following:

• Command line: The Cloud Foundry (CF) command line provides integration for developers that prefer coding without an integrated development environment (IDE). This is also helpful for developing automation scripts with Bluemix. The CF application programming interfaces (APIs) can be integrated with multiple languages, frameworks and services.
• Eclipse: Since Eclipse is widely used by developers, they can continue to use the tools with which they are comfortable. The Cloud Foundry integration can be installed from the Eclipse Marketplace. This provides integration with Bluemix from the Eclipse client.
• Web IDE: Developers can work with the Web IDE directly in Bluemix. This allows modification of the application without any development environment installed on the developers’ laptops.

4. Source control: Bluemix also comes with integration to several source control management (SCM) systems. These include Git, GitHub and Jazz SCM. These environments can be configured to deliver application changes continuously. Open source Cloud Foundry applications can be forked and loaded to Bluemix. This provides a great place to start development of a new project.

5. Services marketplace: Services leverage APIs and software development kits (SDKs) that can quickly and easily be incorporated with Bluemix applications. Although IBM provides many services, Bluemix offers an open and flexible ecosystem which allows other companies to provide services that can be integrated into applications. Companies can be both providers and users of services. Two types of services are available:

The “Managed Service Offering” is not available in the beta, but will be available soon. Services in the marketplace can be at no charge or have a pay as you go (PAYG) pricing model. These services are available to all Bluemix customers.

“User Provided Services” can be added so that organizations can share services within their organization. This promotes more reuse and standardization of services within the company.

 

The Revolution Called AWS

 

Let’s switch back to the old ages.

Imagine you are heading overseas for your travel endeavors.

You have options to go anywhere but wherever you go, you need a place to stay.

 

Traditionally, you would have to build your own shelter upon arrival. You would cut wood for the walls, collect leaves to build shade, and segregate compartment for rooms as required. You would then build a kitchen, toilets, and bed as additional features in the house. At the finest day, your activities will be cooking, sleeping, drinking and showering.

Before you realize it, your holiday has finished and it’s time to come back to reality.

Soon, many great builders arise because of the huge demand for shelters. When you go for a holiday, you could pay to have someone build a house for you. However this is very expensive unless you decide to live at that new place for a long time. And keep in mind disasters do happen. Your floor sinks and your builder runs away with your money, the house is not what you ordered for and now you are in a complete dilemma in an unknown land.

Soon, a service known as ‘hotel’ is created. It provides shelter at locations of your liking, different pricing models based on number of guests, nights, and your preferred exclusivity. In addition, housekeeping service are there to ensure your tenacity in the hotel is at its best. So you always get clean bed sheets, bathroom with toiletries, and alcohol in the fridge for your disposal. Now here comes the hardest choice, pick one.

The great thing about this is, you do not need to know how to build a wall, start a fire, do cooking and so on. The amount you pay is proportional to your chosen preferences and exclusivity. Best of all, you focus on enjoying your holiday.

With this model, it is very obvious that your risks are mitigated, you spend only what is required, and are able to focus on your holiday. Honestly, hotel services are a great innovation!

AWS stack is the hotel service provider in the virtual world, only more powerful. They have expertise in developing and managing a large scale “physical” infrastructures, eg: EC2 (walls, shade, pipes), skillful in providing “features” platform services like VPC, Lambda, RDS, Auto-Scaling and Load Balancing (kitchen, toilet, bedroom, garden). You focus on your main business, they focus on theirs; there is no huge upfront cost; people can build fast, fail fast with minimal cost, and to top it all, it is an extremely powerful component for innovation to happen.

 

“Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery and other functionality to help businesses scale and grow.”

Understanding The Basic Difference

 

A product designer in the Internet space is someone who’s a hybrid between a visual/interaction designer and a web/frontend programmer. This person ideally designs in code. Primarily works around transactional products.

UX designer ideally should be solving for everything that comes under the UX umbrella, including branding, user research, semiotics, information architecture, interaction design. More often than not, this role is equalled to wire-framing jockey or interaction designer.

The difference between “product designer” and “UX designer” are based on semantics mostly, rather than a crisp and widely understood definition. Many product designers consider themselves to be designers who design experiences. Many companies do not differentiate between services and products also as such.

A UX designer is a broader term since you could use it to describe someone who designs experiences that aren’t products, for example, like a check-in experience at a hospital. But “product” these days is a fairly broad term as well, as many people who are “product designers” actually spend their time designing end to end services as well.

A Product Designer is responsible for the following:

• Understand the customer requirements from the Requirements Specification document and start building user interface mockups

• Iterate with the Product Manager and in turn customers to arrive at an interface that is acceptable and deemed most user friendly

• Develop the interface using code (in case of a software product) or create CAD designs (in case of a physical/mechanical product)

• Participate in the development process and monitor if the final outcome matches user accepted designs

 

A UX Designer is responsible for the following:

• Look at the overall end user’s requirement from an end user’s point of view

• Evaluate what kind of thoughts, feelings and emotions that users go through when using the intended product

• Provide guidelines or suggestion to PM, designers and developers on what could be changed so that the end user feels positive about the experience of using the product

• Work with the Product Manager to understand the customer touch points after delivery and help design the after sales experience for customers

 

The Definition of Product Designer and UX Designer

 

The product designer handles the overall function and working process of the product. They are the guardians of user needs. UX designers are responsible for the function of the user interface and user-friendly experience.

 

Tools for Product Designer

Mind mapping tools: Xmind. It is easy to use and has a concise interface. There is no learning cost.

Sketch tools: paper and pen. It’s simple, efficient, easy to modify, low cost.

Low-fidelity prototyping tool: Mockplus. It is easy to use and quick to interact. It can quickly build low -fidelity prototypes.

High-fidelity prototyping tool: Sketch. It can make rough wireframe more standardized and has good visual effects.

Tools for UX Designer

Wireframe design tools: Wireframe.cc . It has no complicated icons and toolbar. Both of interface style and operation are the minimalist.

Interactive design tools: Adobe XD. It positions itself with a lightweight vector and prototype software. You can freely switch interface design and prototype interaction.

Prototype design tools: Axure Rp. It supports high fidelity and low fidelity. It has good documentation support. The plug-in library of it can be customized.

So, let’s put it forward in a broader perspective: 

Product Designer is yet another term that dances around the Product Management and UX roles.  The title is meaningless without knowing about the context of the product and the complementary roles. Is there a Product Owner? A Customer Researcher? A Visual Designer? Someone from Product Marketing?

As always, start with definitions of what’s needed to deliver successful products, the whole chain from customer discovery and value definition to the business model definition to building the product to launching it to market. Note, many of the implied activities need to happen in parallel, so don’t assume that an extremely talented and broadly experienced person can do everything. Then understand who owns or contributes to which part of the delivery chain. Roles will emerge from there. The titles are secondary.

The Famous Node.js Apps

Node.js is a JavaScript runtime that runs on top of Google’s open-source JavaScript engine called V8. Pairing JavaScript’s naturally event-driven, asynchronous coding style with non-blocking I/O libraries makes Node.js fast, lightweight, and efficient.

It’s built to handle asynchronous I/O from the ground up and is a good match to a lot of common web- and network-development problems.  In addition to fast JavaScript execution, the real magic behind Node.js is called the Event Loop. To scale to large volumes of clients, all I/O intensive operations in Node.js are performed asynchronously.

In addition to it’s innate capabilities, Node.js has a thriving open source community which has produced many excellent modules to add additional capabilities to Node.js applications. One of the most famous is  Socket.io, a module to manage persistent connections between client and server, enabling the server to push real-time updates to clients. Socket.io abstracts the technology used to maintain these connections away from the developer, automatically using the best technology available for a particular client.

It is the pivotal tool for many big giants, and has helped them build a huge business.

Let us have at a few web apps that used Node.js
