/massu-test

Runs tests with intelligent failure analysis, identifies coverage gaps, and can generate missing tests for untested modules.

Usage

/massu-test [mode]

Modes

Default Mode (No Arguments)

Runs all tests using vitest and provides:

• Test execution summary (pass/fail counts)
• Failure analysis with stack traces
• Suggested fixes for common failure patterns
• Coverage summary if available

--affected

Runs only tests for files that have changed:

• Detects modified files via git status
• Identifies related test files
• Runs targeted test suite
• Faster feedback for incremental development

--coverage

Generates a coverage gap report:

• Identifies modules without tests
• Calculates coverage percentages by module
• Prioritizes critical paths (used by >3 modules)
• Outputs actionable coverage improvement plan

--generate [module]

Creates tests for an untested module:

• Analyzes module exports and functions
• Generates vitest test scaffolding
• Includes example test cases
• Follows project testing patterns

--fix

Attempts to fix failing tests automatically:

• Analyzes test failure messages
• Identifies common patterns (type mismatches, missing mocks, async issues)
• Applies targeted fixes
• Re-runs tests to verify fixes

When to Use

• Before commits: Run /massu-test to ensure all tests pass (CR-7 requirement)
• To check coverage gaps: Use /massu-test --coverage to identify untested modules
• To bootstrap tests: Use /massu-test --generate [module] for modules without test coverage
• During development: Use /massu-test --affected for faster feedback on changed code
