Mobile App Testing Process Explained


Testing a mobile application is an important process that mobile apps undergo before their release to the public. Rigorous quality assurance testing is necessitated by the growing variety of mobile devices with different screen sizes, resolutions, processing power, operating systems, and networks. The mobile app testing process is crucial to validate if the app performs well under different circumstances and provides the desired quality, performance, and user experience.

Mobile App Testing Process

For mobile app developers, it’s important to maintain a well-structured mobile app testing strategy to ensure an app achieves its objectives and the users’ expectations. In this article we’re going to outline one such testing methodology and guide you through each step, starting with the documentation.

Test Documentation

A clear plan is essential for the successful execution of mobile app testing. This involves the creation of different test documentation. This helps define the goals to be achieved at each stage of the test procedure. Typically, the test documentation process involves creating documents including:

  • Test Plan
  • Test Cases
  • Test Execution
  • Summary Report
  • Bug Report

A Test Plan is created by establishing the objectives to be achieved throughout the entire testing process. The document incorporates the approach, risks, possibilities, and recommendations, defect management processes, and the resource requirements for each test objective.

The test plan document also stipulates the details of each approach performed for mobile app testing by identifying the features to undergo testing, varying test scenarios, user workflows, technical annotations, and release criteria.

Test Plan for Mobile App

Test Cases help validate the successful and acceptable implementation requirements of the application. The test case document is prepared by including the set of test actions, test and user input data, execution conditions, and expected results developed for test implementations.

The Test Execution Report is prepared for each of the test types. This report is used to establish the general status of the test execution process on an iteration-by-iteration basis.

Finally, the Bug Report is prepared by including the failed test cases in the test execution report, error description, test case id, screens on which the error is reported, priority and severity of the bug.

Functionality Testing
Functionality testing analyzes users’ interactions with the software and the resulting output from the application. In this phase, the application has to be tested to verify its acceptable behaviors as per the core functions and project requirements tailored to the target users. At this point, testers have to make sure that the app’s device-specific functions are fully functioning. These include but aren’t limited to:

  • Camera
  • Accelerometer/Positional Sensors
  • GPS
  • SMS Integration
  • Bluetooth
  • 3D Accelerated Graphics

Usability Testing
The user experience is a crucial factor that decides how easily users can navigate a mobile application. Usability in apps based on the input of a wide variety of testers with varying technological proficiencies is an important step of testing. Usability tests help identify issues related to the app’s usability, content, and navigation. These tests verify if the application is achieving its goals and garnering the desired response from users.

Compatibility Testing
The compatibility of a mobile app is another aspect that must be closely tested. First, testers have to attain a clear understanding of the device fragmentation scenario in the mobile device market. Mobile devices vary widely in form factors, screen resolution, and processing power. Testing must be incorporated to ensure the app functions well across a variety of mobile devices by analyzing all aspects of the app’s UI, including content visibility, readability, and functionality. Network compatibility is another important aspect that must be examined during this phase to ensure the app works across different network operators without bugs.

Application Performance Testing

Performance Testing
Performance matters. No one likes to use an app if it doesn’t perform well on their device. Generally, the performance of the app must be verified from both the server and client side. Performance tests check how an app behaves under different data-related situations, such as data of various volumes, massive data downloads from the server, and data growth. Conditional tests also check the app’s performance under situations like low battery, bad network coverage, and low available memory.

Security Testing
Security testing has become a critical, necessary step in mobile app development. No mobile app creator wants to jeopardize their users’ personal information, bank credentials, or even medical records. Security testing helps developers protect the app against hacking vulnerabilities and ensures the app’s data, authentication, authorization policies, data security, encryption protocols, and session management comply with a developer’s security standards and industry best practices.

As you can see, testing a mobile application is a thorough and time-consuming process. It takes teams of experts with established backgrounds in quality assurance to ensure that a mobile application ships bug-free and secure. It’s important to work with the right mobile app developer who can create quality products and offer the testing infrastructure to ensure an app launches successfully and safely.
