By automating the regression testing process, Claude can quickly identify and address potential issues before they impact users. ## How It Works 1. **Identify Regression Tests**: The user marks specific tests as part of the regression suite using the `--mark` flag. 2. **Execute Regression Suite**: The skill runs the designated regression tests. 3. **Analyze Results**: The skill analyzes the test results, highlighting failures and potential flaky tests. ## When to Use This Skill This skill activates when you need to: - Run the regression test suite before deploying new code. - Mark a specific test as part of the regression suite. - Investigate potential regressions after making code changes. ## Examples ### Example 1: Running the Regression Suite User request: "run regression tests" The skill will: 1. Execute all tests marked as part of the regression suite. 2. Report the results, including any failures or flaky tests. ### Example 2: Marking a Test for Regression User request: "track regression --mark test_example" The skill will: 1. Mark the test `test_example` as part of the regression suite. 2. Confirm that the test has been added to the suite. ## Best Practices - **Test Selection**: Choose tests that cover critical functionality and are likely to be affected by changes. - **Frequency**: Run the regression suite frequently, especially before deployments. - **Analysis**: Carefully analyze test failures to identify the root cause of regressions. ## Integration This skill can be integrated with other testing and CI/CD tools to automate the regression testing process as part of a larger development workflow. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/jeremylongshore) — claim your Tome and manage your conversions.
