Run tests and systematically fix all failing tests using smart error grouping. Use when user asks to fix failing tests, mentions test failures, runs test suite and failures occur, or requests to make tests pass.

# 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 Prioritize groups by: - Number of affected tests (highest impact first) - Dependency order (fix infrastructure before functionality) ### 3. Systematic Fixing Process For each group (starting with highest impact): 1. **Identify root cause** - Read relevant code - Check recent changes with `git diff` - Understand the error pattern 2. **Implement fix** - Use Edit tool for code changes - Follow project convent

About this skill
What does the test-fixing skill do?

Run tests and systematically fix all failing tests using smart error grouping. Use when user asks to fix failing tests, mentions test failures, runs test suite and failures occur, or requests to make tests pass.

How do I install it?

Run `npx skills add mhattingpete/claude-skills-marketplace --skill test-fixing --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From mhattingpete/claude-skills-marketplace, a repository with 656 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
