A sudden crash or a glitch in functionality can cause users to abandon the app, translating to lost customers and dwindling revenues.
Consider this: statistics reveal that 80% of users discard an app that exceeds expectations. Moreover, 50% of users quickly uninstall apps that take up too much storage space, while 48% give up on those that lag. These figures drive home the importance of thorough mobile app testing.
The journey of mobile application testing is a step-by-step process. It begins with planning and control, analysis and design, implementation and execution. The following steps involve evaluating the exit criteria, reporting, and concluding with test closure activities. To streamline this process, there’s an array of mobile app testing techniques and tools, including Appium, TestComplete, Robot Framework, Espresso, and Xamarin.UITest, and XCUITest.
The planning phase is where we map out the objectives, methods, and scope of the testing. During the analysis and design phase, we identify test conditions and design test cases to ensure all app features are meticulously covered. Following this, we execute these test cases in the implementation phase. We then compare the actual and expected outcomes to spot discrepancies.
Evaluating the exit criteria involves determining whether the pre-set exit criteria have been fulfilled. If these criteria are met, we can conclude the testing. The final stage, test closure, includes wrapping up the testing, archiving data, and extracting valuable lessons for future projects.
Mobile application testing is a linchpin in today’s digital landscape. By enabling the delivery of high-quality mobile apps, businesses can offer optimized user experiences, a game-changer in the highly competitive realm of mobile applications. Ultimately, adequate mobile app testing is the secret sauce for meeting user demands and offering stellar user experiences.
In the constantly evolving landscape of mobile applications, establishing efficient and robust app testing strategies is fundamental to ensuring the success of an app. These strategies aim to ensure flawless performance across various platforms, enhance user experience, and secure sensitive user data, among other vital aspects. This section provides a deep dive into the most effective strategies for mobile app testing.
With users having the liberty to choose from various devices and operating systems, ensuring the app’s seamless performance across these platforms is crucial. Testers can use emulators alongside physical device testing to make this process more cost-effective and yield excellent results.
Security testing is necessary since users often share important sensitive data through their devices. A robust security testing strategy involves understanding the platforms on which the application will run and identifying potential attack vectors. Moreover, it includes developing multiple defense mechanisms and testing the app from an attacker’s perspective to better understand the weaknesses and possible exploits.
While many users may have access to high-speed internet, a considerable number still need to be challenged by inconsistent network reception and low-speed internet. In such scenarios, testers must ensure the app’s consistent performance across different network speeds and conditions, from 1G to LTE to WiFi, and consider sudden network changes and even disconnections.
Different devices come with different specifications and dimensions. Screen size is critical in testing as it can reveal bugs that negatively affect the app’s layout and, ultimately, the user’s digital experience.
Several apps leverage battery-intensive processes, such as storing and sharing heavy data, streaming content, and using geolocation elements. Thus, testers need to identify the parts of the app that consume the most battery and modify those accordingly.
Users often refrain from installing apps that consume too much space. Thus, developers and testers must focus on optimizing the size of the app without compromising its usability and offerings. Furthermore, they should ensure that the app size does not exceed a specific limit with each update or new release.
A plethora of permission requests from an app can raise privacy concerns among users. Testers need to ensure that the app doesn’t seek any permission that isn’t necessary for its functionality. Moreover, the permission screen for any eliminated feature of the app should be removed.
App upgrade testing ensures that the app runs smoothly during an upgrade due to a mismatched version number. It also verifies the retention of user preferences and saved data across different versions.
Performance testing is a vital element in the app testing pipeline. It checks the application’s response time and latency across numerous scenarios and use cases, particularly under heavy user load.
Creating a high-quality mobile application requires a thorough, step-by-step testing process that ensures all aspects of the app’s functionality, usability, and security are up to standard. By examining and integrating ideas from both the BrowserStack and Testrig Technologies articles, we can define this comprehensive process in more detail:
The process begins by outlining the testing strategy, including determining prerequisites, identifying the targeted devices, figuring out the app type, and creating a test plan for the cases that need to be executed. Deciding on the manual or automated testing type is essential at this stage. Automation is beneficial for frequent use cases, tests with predictable outcomes, tests needed for various devices, and unit testing.
Manual, automated, and cloud simulator testing ensures the mobile application performs optimally across all Android and iOS devices. This approach helps uncover potential defects and ensures the app meets its objectives.
Test cases, which consist of a series of steps to execute a specific app test, are crucial to the process. While test cases are used during manual testing, test scripts find applications in automation testing. These are designed according to the mobile app’s scenarios.
