Test Framework Layers
  • Enums Layer: Contains enum classes like Status representing fixed sets of values.
  • Page Objects Layer: Encapsulates UI elements and actions (e.g., LoginPage).
  • Tests Layer: Contains test classes using JUnit, including parameterized tests with @EnumSource.
  • Utilities Layer: Helper classes and methods for common test tasks.
  • Configuration Layer: (Not shown in folder) Manages environment and test settings.
Configuration Patterns

Use junit-platform.properties or system properties to configure test execution.

  • Define environment variables for different test environments.
  • Use Maven or Gradle profiles to select browsers or test parameters.
  • Keep enum classes simple and stable to avoid breaking tests.
Test Reporting and CI/CD Integration
  • JUnit generates XML reports compatible with CI tools like Jenkins or GitHub Actions.
  • Use plugins to visualize test results and failures clearly.
  • Integrate test runs in CI pipelines to run parameterized tests automatically.
  • Reports show each enum value tested separately with pass/fail status.
Best Practices
  • Use @EnumSource to run tests for all or selected enum values, ensuring full coverage.
  • Keep enum values stable to avoid test flakiness.
  • Use descriptive test method names to clarify which enum value is tested.
  • Combine @EnumSource with other parameter sources for flexible tests.
  • Use explicit imports and avoid wildcard imports for clarity.
Self Check

Where in this folder structure would you add a new enum class Priority to use with @EnumSource in tests?

Key Result
Use @EnumSource in JUnit tests to run parameterized tests over enum values for clear, maintainable coverage.
