Test Framework Layers

• Database Layer: Contains stored procedures and test data scripts.
• Test Scripts Layer: SQL scripts that call stored procedures with test cases and verify outputs.
• Utility Layer: Helper scripts (e.g., Python) to connect to the database, run SQL scripts, and fetch results.
• Configuration Layer: Holds database connection details and environment settings.
• Reporting Layer: Generates readable test reports from test execution results.

Configuration Patterns

• Use a db_config.json file to store database host, port, username, password, and database name.
• Support multiple environments (dev, test, prod) by having separate config sections or files.
• Use environment variables or secure vaults to keep credentials safe and avoid hardcoding.
• Allow test runner scripts to read config dynamically to connect to the correct database.

Test Reporting and CI/CD Integration

• Generate HTML or XML reports summarizing which stored procedure tests passed or failed.
• Include details like input parameters, expected vs actual results, and error messages.
• Integrate test execution into CI/CD pipelines to run tests automatically on code changes.
• Fail the build if critical stored procedure tests fail to prevent faulty database code deployment.

Best Practices

• Isolate test data: Prepare and clean up test data before and after each test to avoid side effects.
• Use assertions on stored procedure outputs to verify correctness.
• Test edge cases and error handling inside stored procedures.
• Keep test scripts simple and readable, focusing on one scenario per test.
• Automate tests to run frequently and catch regressions early.

Self Check

Where in this folder structure would you add a new test script to verify a recently added stored procedure?

Key Result

Organize stored procedure tests with clear layers: SQL test scripts, utilities for DB access, config for environments, and reporting for results.
