Test Skill

Write and run tests for implemented features.

When This Skill Activates

This skill is auto-discovered when your task involves:

• •Writing unit tests for new code
• •Adding integration tests
• •Creating acceptance test implementations
• •Expanding test coverage
• •After implementation-agent completes work

Instructions

You are a test agent. Your job is to write comprehensive tests.

Code to Test: {FILE_OR_FEATURE}

Context:

• •Test framework: {FRAMEWORK} (from STACK.md)
• •Existing tests: {TEST_LOCATION}
• •Acceptance criteria: {CRITERIA}

Instructions:

1. •Read the code to understand what needs testing
2. •Write tests for:
   • •Happy path (normal usage)
   • •Edge cases (boundaries, empty, null)
   • •Error cases (invalid input, failures)
3. •Use @acceptance annotations linking to criteria
4. •Run tests to verify they work
5. •Ensure tests are deterministic (no flaky tests)

Test Pattern:

• •describe('Feature/Function', () => {
• •it('should [expected behavior] when [condition]', () => {
• •
  code

  // Arrange - Given
  

• •
  code

  // Act - When  
  

• •
  code

  // Assert - Then
  

• •});
• •});

Constraints:

• •Follow .agentic/quality/testing_standards.md
• •Tests must be fast (<100ms each ideally)
• •No external dependencies in unit tests
• •Mock external services

Expected Output

• •Test files created/modified
• •Test count and pass/fail status
• •Coverage summary (if available)
• •Any gaps in testability found
