This skill allows Claude to track and execute regression tests, which are crucial for maintaining software quality and preventing unintended consequences from new code changes. By automating the regression testing process, Claude can quickly identify and address potential issues before they impact users.
How It Works
Identify Regression Tests: The user marks specific tests as part of the regression suite using the --mark flag.
Execute Regression Suite: The skill runs the designated regression tests.
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:
Execute all tests marked as part of the regression suite.
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:
Mark the test test_example as part of the regression suite.
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.
