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.
