name: testing description: Write test cases to build confidence in code correctness and identify edge cases or regressions.

Skill: Testing

See also: AGENT_SYSTEM.md

Phase

• Validate (proactive) or Change (when fixing broken tests)

Purpose

• Build confidence in correctness by writing test cases that verify behavior.
• Identify edge cases and regressions early.

Use When

• "Write tests for this"
• "Test coverage is low"
• "Add a test to verify X"
• "Fix failing tests"

Inputs to Request (only if blocking)

• What code or behavior should be tested?
• What test framework/runner is available?
• Coverage target (if any)?

Workflow

• Understand the code:
  • What's the happy path?
  • What are edge cases (null, empty, errors)?
  • What should fail gracefully?
• Plan test cases (small scope):
  • 3–5 core scenarios per function/component
  • At least one failure case
• Implement tests:
  • Use existing test framework
  • Follow repo style
  • Keep tests fast and isolated
• Proof of Life:
  • All tests pass
  • Run command: npm test (or equivalent)
  • Show test output

Output

• Test cases added (brief list)
• Coverage impact (if measurable)
• Proof of Life (test run output)

Memory

• Append one line to JOURNAL.md if this closes a testing gap
