Cloud based performance testing are different from traditional application testing with additional complexity, such as the testing of multiplatform, networks, multiple operating systems (OSs) as well as different devices. These services are needed to test the function, performance, compatibility and other details of a mobile application, using both manual and automated tests. While the testing this market refers to is that of applications residing on mobile handheld devices, the testing must also take into account the data being gathered or supplied to embedded devices and sensors with the Internet of Things (IoT) becoming more prominent. User experience is key in mobility by creating unique requirements for the testing process. With digital business and customer experience, applications and data are increasingly available and visible to external constituents — especially customers. Thus, quality, reliability, security, and adaptability needed for external use of systems are far beyond internal usage.

With almost 85% millennials using apps on their smartphones, enterprises need to continuously deploy launch quality, seamlessly functioning applications to stay ahead in this digitally transforming world. Wetest provides deep experience in cross-browser testing for mobile applications for both functional and non-functional (Manual Automated) testing of mobile applications. Cigniti’s Mobile Testing Center of Excellence (TCoE) constitutes of 500+ mobile testing professionals. While our mobile app testers are certified in various commercial open source mobile testing tools, our test architects engineers have 6+ years of experience in mobile testing for various domains such as Banking, Insurance, Travel, Retail, and more leveraging industry leading mobile testing tools best practices.

Testing in general, but applying also to game testing, there are two different forms of testing that can be categorized as a Black-Box and White-Box testing. These definitions are well-known in software testing world but process-wise aren’t different with game testing. Only their goals are slightly different in-game testing:
1.Black-box testing – focuses on the functional and overall playability aspects of the game. In this type of testing, for example, testing the graphical user interface, user experience or any visual appearance is in the key role. Menus, graphical elements, special effects, animations, and the actual gameplay are those under test with Black-box approach.
2.White-box testing – focuses on the architectural, integration and systemic aspects of the mobile game: how third-party components, databases, social media/external entities, as well as graphics/game engines, audio player and so on are integrated into your game. In the test automation context, black-box testing focuses on controls, capabilities, features, gameplay, and automates the flow of testing. For this, it is typically recommended to build test scripts that know how the game is progressing, what kinds of faulty states could there be, and also focus on image recognition. As many graphics cannot be recognized as a control mechanism – buttons, menus, sliders etc. – image recognition will help to identify those that are meant for controlling (and not just as a graphical element).

Methods Used in Coud Based Performance Testing
The testing methodology and used forms of testing aren’t too different from app testing. The most important ones when it comes cloud based performance testing are as follows:
Functional testing is probably the most common method in cloud based performance testing. Typically functional testing is associated with manual testing and playing ‘game through’. However, to be agile, all functional testing should be automated. Functional testing – with help of test automation frameworks- requires some basic understanding of programming and setting up an environment for testing. Automated functional testing can reveal issues related to user interface (and graphics), stability, game flow/mechanism, and integration of graphics assets.
Compatibility testing is all about making that game compatible across different devices. The typical misconception with compatibility testing is that it will be only done with the final version of the game. If compatibility testing is done during all development phases – known also as smoke testing – it can help to reveal incompatibility issues with any parts of the game, its third-party components or integrations with those actual devices that end-users use. This is very important to get the game working robust and well across all possible device variants – hardware and software.
