Mobility - Key Challenges Mobile applications are getting more sophisticated, significantly enhancing the requirement for functional testing. To tackle this, test organizations are searching for alternatives for primary manual testing. Automated testing is a highly efficient method to mobile app testing which can offer significant returns, provided it is put into action using right architecture and tools, factoring in cross-platform difficulties. The following particular types of testing also need to be automated: Cross-platform compatibility testing: This is compulsory as there are increasing number of handsets and platforms. User-experience testing: Most testing companies have limited experience with execution and design of usability tests. Field or network testing: should be done in a geographically distributed environment so as to take into account a variety of network types. Structural challenges: Integrating testing tool sets for mobile into present IT systems is an important hurdle. Test Automation Mechanisms for Mobile Apps A mobile website testing can be automated in any of the following three ways: User-agent based automation: This method leverages user agent add-ons that are present along with popular browsers like Google chrome and Mozilla Firefox. The user agents help render the web content that would show on the device onto a regular desktop browser. The automation of the functionality can be carried out by utilizing popular tools like Selenium, QTP or RFT- each of which supports all desktop browsers. Cloud based automation: Cloud based test automation sellers support web based QA across platforms. Cloud based automated solutions are very effective as they are provided as a unified package. Lab based automation: This method comprise of setting up tools in a test environment and giving power to simulators or physical devices to automate utilizing popular open-source tools like Selenium. Web driver supported device browsers and simulators are best applicable here. Mobile Application Tools/Platform-specific Tools: Device platform-specific tools trustworthiness is a high priority. Platform sellers supply tools like Robotium for Android and ios instruments for IOS to offer this facility. However, to make use of this facility, it demands additional programming skills. 6

Mobile application testing tools selection criteria There are many applicable techniques which make testing applications on mobiles more efficient and effective. It is important to ensure functional and non-functional compliance of the applications on devices and mobile automation. It is also important to establish labs for testing the mobile applications. Some basic criteria for mobile application testing comprise the use of multiple browsers, emulators, various operating systems and the unique types of testing needed for GUI, filed and interruption testing. There are around 10 key principles that needed to be considered while choosing the right automation tool. Ten Key principles for choosing the right automation tool It is a good practice to initiate a proof of concept (PoC) on important platforms before identifying a tool set or a tool. One tool might not gain cross-platform automation aim. During evaluation of test automation tools, companies must not overlook the way they integrate with test management environments. One beginning stage is to find reusable scenarios across platforms and cluster them accordingly. This provides the production of an apt, time saving framework. For native apps, select critical test cases which are apt across releases as automation candidates and make sure that there is multi-browser compatibility and cross-platform reusability. Always pay attention to various form factors while identifying test coverage, especially for the mobile web. Consider various connectivity aspects for running automation. Additionally, the below recommendations will be helpful regarding your test automation procedure: Perform feasibility tests for tool, as mobile platforms and technology vary. Choose tools that support both platform devices and simulators, as you can mix and match simulators and devices to optimize automation on various platforms. Goal should be to achieve automation in non-functional places - hardware scenarios and interruption scenarios that comprise battery state changes. Always optimize on platform support: At some places, one or more tools might be needed for performing automation. Find out various device support and versions support. Find the usage of utilities and reusable functions which increase the value of automation. Ensure ROI per every mobile platform and execution duration as part of the tool consideration procedure. Look for chances for early automation, as most mobile projects are agile. Integration should be achieved with application lifecycle management and test management tool. Pay attention for data driven automation support: Iterations in the procedure will enhance coverage and ROI. 7

Good candidates for automation are test cases with repeated business logic, data driven tests or functional flows. Data driven tests can be like smoke test to build acceptance testing, synchronization testing, regression testing, and compatibility testing, GUI testing and testing non-dynamic UI components, along with cross-platform functional testing. Conclusion Fig 3: Mobility Eco system Although there are challenges in mobile application testing, but careful selection of target devices, tools that maximise automation and connectivity options can offer a cost effective mobile testing procedure. A right selection of target devices and combining usage of physical devices and simulators can maximise test coverage, eliminating the need to test every feature on each device. The usage of Wi-Fi networks for most of the testing combined with network simulation tools can minimize the cost and complexity of testing of different cellular networks. The best way to reduce the test procedure along with long term costs is to maximise automation. While selecting automation tools, factors like script usability, support for applicable mobile platforms and total cost of ownership should be considered. The challenges of mobile application testing can be effectively addressed by combining the solutions to mobile specific aspects of testing the application along with traditional best practices.
