Improve Test Quality
Target: $ARGUMENTS
If no argument provided, scan the full test suite.
Step 1: Gather Requirements
- Run test suite to establish baseline:
bun run test 2>&1 | tail -20
- Scan test files for quality issues:
- Weak assertions (
toBeTruthy, toBeDefined instead of specific values)
- Missing edge cases (no boundary values, no error paths)
- Implementation coupling (testing internals rather than behavior)
- Missing error path coverage
- Duplicated setup that could indicate missing abstractions
- Identify 10-20 test files with highest improvement potential, noting:
- File path
- Issues found (weak assertions, missing edge cases, etc.)
- Estimated impact of improvement
Step 2: Compile Brief and Delegate
Compile the gathered information into a structured brief:
Improve test quality across the test suite.
Test files needing improvement (ordered by impact):
1. [test file] - [issues found]
- Weak assertions: [count]
- Missing edge cases: [description]
- Implementation coupling: [description]
2. ...
Verification: `bun run test` -> Expected: All tests pass, improved assertions and coverage
Invoke /lisa:implement with this brief to create the implementation plan.
