  • Consider real-world scenarios, user interactions, edge cases, and errors. 
  • Organize test cases into suites (e.g., UI, database, integration). 

Execute Test Cases  

  • Systematically execute test cases following the plan and suites. 
  • Keep track of the test findings, including any defects or difficulties discovered. 
  • Document outcomes in a comprehensive test report. 

Analyze Test Results  

  • Review the test report to identify defects and issues. 
  • Sort flaws according to their impact and severity. 
  • Provide the development team with a thorough report of any defects. 

Retest and Verify Fixes  

  • After the defects are fixed by development, retest the application. 
  • Ensure that fixes are effective and don’t introduce new problems. 
  • Document the retesting process and outcomes in a recent test report.
