Test Framework Layers
  • Tests Layer: Contains test files like test_identity.py where is and is not identity checks are performed.
  • Utilities Layer: Helper functions or test data used across tests.
  • Configuration Layer: Holds environment settings, credentials, and test parameters in config.yaml.
  • Fixtures Layer: conftest.py provides reusable setup and teardown for tests.
  • Reporting Layer: Stores test reports generated after test runs.
Configuration Patterns

Use a config.yaml file to store environment details and test parameters. Load this config in conftest.py to provide fixtures with environment info.

Example config.yaml snippet:

environment: "test"
base_url: "https://example.com"

Use pytest command line options to select environments or toggle verbose output.

Test Reporting and CI/CD Integration
  • Use pytest --html=reports/latest_report.html to generate readable HTML reports after test runs.
  • Integrate pytest runs in CI pipelines (GitHub Actions, Jenkins) to run tests on each commit.
  • Failing tests with identity assertion errors will be clearly shown in reports.
  • Use pytest markers to group identity tests for selective runs.
Framework Design Principles
  1. Clear Test Naming: Name tests to reflect identity checks, e.g., test_object_identity.
  2. Use Fixtures: Share test objects via fixtures to avoid duplication.
  3. Explicit Assertions: Use assert a is b or assert a is not b for clarity.
  4. Isolate Tests: Each test should check one identity condition to keep failures clear.
  5. Readable Reports: Generate HTML reports to easily spot identity assertion failures.
Self Check

Where in this folder structure would you add a new test file to check identity of user session objects?

Key Result
Organize pytest tests with clear layers: tests, utilities, config, fixtures, and reporting for identity checks.
