Test Framework Layers for Use Case Testing

• Use Case Documents: Written descriptions of user interactions and expected outcomes. These guide test creation.
• Test Scripts: Automated tests that follow the steps in the use cases to verify the system behaves as expected.
• Utilities: Helper functions to support test scripts, such as data setup or common actions.
• Configuration: Settings for different environments, test data, or parameters to run tests flexibly.
• Reports: Output from test runs showing which use cases passed or failed.

Configuration Patterns for Use Case Testing

Use a config.yaml file to store environment details like URLs, credentials, and test data. This allows running the same use case tests in different environments without changing code.

environment: staging
base_url: https://staging.example.com
credentials:
  user: testuser
  password: password123

Load this config in test scripts to keep tests flexible and maintainable.

Test Reporting and CI/CD Integration

• Generate clear reports after test runs showing which use cases passed or failed.
• Use simple HTML or XML reports for easy reading and sharing.
• Integrate tests into CI/CD pipelines to run use case tests automatically on code changes.
• Fail the build if critical use cases fail to ensure quality.

Best Practices for Use Case Testing Framework

1. Write Clear Use Cases: Use simple language describing user goals and steps to avoid confusion.
2. Map Tests to Use Cases: Each automated test should directly reflect a use case scenario.
3. Keep Tests Independent: Tests should not depend on each other to avoid cascading failures.
4. Use Configurations: Separate environment and data settings from test logic for flexibility.
5. Regularly Update Use Cases: Keep use case documents and tests in sync with application changes.

Self Check Question

Where in this folder structure would you add a new automated test script for a use case about "Reset Password"?

Key Result

Organize tests around clear user scenarios with separate use case documents, automated scripts, and flexible configuration.
