  • Unit testing: Examines the software’s individual components, including module behavior, code-level functions, and error handling

  • Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together 
  • Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
