Test Fixing is cataloged under Quality on DirSkills. Test Fixing comes from a repository tagged ai-agents, ai-tools, anthropic, automation and claude-code.

Documentation

README

Excerpt

Test Fixing

Systematically identify and fix all failing tests using smart grouping strategies.

When to Use

Explicitly asks to fix tests ("fix these tests", "make tests pass")
Reports test failures ("tests are failing", "test suite is broken")
Completes implementation and wants tests passing
Mentions CI/CD failures due to tests

Systematic Approach

1. Initial Test Run

Run make test to identify all failing tests.

Analyze output for:

Total number of failures
Error types and patterns
Affected modules/files

2. Smart Error Grouping

Group similar failures by:

Error type: ImportError, AttributeError, AssertionError, etc.
Module/file: Same file causing multiple test failures
Root cause: Missing dependencies, API changes, refactoring impacts

This is the opening of the README. Read the full README on GitHub.
