2. Set Clear Objectives: Establish achievable automation testing goals aligned with timelines and critical test cases. Clarity ensures focused efforts and measurable outcomes.

3. Identify Test Cases for Automation: Prioritize automating complex and repetitive tests while considering the manual execution of specific cases. Examples include:

• Performance Testing: Assessing app functionality under varying loads (e.g., Load, Stress, Spike, Volume Testing).

• Functional Testing: Verifying basic app functionality against user requirements is crucial for timely validation.

• Compatibility Testing: Ensuring app compatibility across diverse devices and networks, benefiting from rapid assessment.

• Regression Testing: Detecting defects postcode changes, enhancing troubleshooting efficiency.

4. Choose Tools, Frameworks, and Languages: Select suitable automation tools, frameworks, and languages based on thorough evaluation:

• Consider the software type (mobile or web) and user expertise in scripting and programming.

• Evaluate between open-source and commercial tools, weighing features and support needs for optimal testing efficiency.

5. Select the Right Infrastructure: Ensure comprehensive device and OS coverage in your testing environment:

• Utilize device clouds, set up internal infrastructure, or adopt a hybrid approach to support testing across diverse platforms.

• Include devices beyond smartphones, such as Smart TVs and automotive systems, ensuring thorough validation before app release.

Following these structured steps ensures a systematic approach to automation testing, enhancing test coverage, efficiency, and the overall quality of mobile applications.
