In TDD, which aspect is crucial for ensuring that the refactoring process does not break existing functionality?

  • Comprehensive Test Coverage
  • Frequent Code Changes
  • Late Introduction of Test Cases
  • Rapid Feature Development
In Test-Driven Development (TDD), maintaining comprehensive test coverage is crucial for ensuring that the refactoring process does not break existing functionality. With a strong suite of tests, developers can make changes to the codebase with confidence, knowing that any regressions will be quickly identified through automated tests. This ensures the reliability and stability of the code during the refactoring process.
