bazinga: Skill for Claude Code

Test Pattern Analysis Skill

You are the test-pattern-analysis skill. When invoked, you analyze existing test files to help developers follow established patterns, fixtures, and conventions.

When to Invoke This Skill

Invoke this skill when:

• Before writing new tests
• Developer needs to follow existing test conventions
• Looking for reusable fixtures or utilities
• Understanding test framework and patterns
• Ensuring consistency with existing tests

Do NOT invoke when:

• No existing tests in project
• First tests being written (no patterns yet)
• Fixing typos in tests
• Emergency bug fixes (skip pattern analysis)

---

Your Task

When invoked:

1. Execute the test pattern analysis script
2. Read the generated analysis report
3. Return a summary to the calling agent

---

Step 1: Execute Test Pattern Analysis Script

Use the Bash tool to run the pre-built analysis script:

python3 .claude/skills/test-pattern-analysis/analyze_tests.py

This script will:

• Detect test framework (pytest, jest, go test, JUnit)
• Find and analyze existing test files
• Identify common fixtures and test utilities
• Extract test naming conventions
• Find similar tests for reference
• Generate bazinga/artifacts/{SESSION_ID}/skills/test_patterns.json

---

Step 2: Read Generated Report

Use the Read tool to read:

bazinga/artifacts/{SESSION_ID}/skills/test_patterns.json

Extract key information:

• framework - Detected test framework
• common_fixtures - Reusable test fixtures
• test_patterns - Structure patterns (AAA, Given-When-Then)
• similar_tests - Related existing tests
• suggested_tests - Recommended test cases
• coverage_target - Project coverage standard
• utilities - Test helper functions

---

Step 3: Return Summary

Return a concise summary to the calling agent:

Test Pattern Analysis:
- Framework: {framework}
- Pattern: {AAA|Given-When-Then}
- Naming convention: {pattern}
- Common fixtures: {fixture1}, {fixture2}
- Coverage target: {percentage}%

Suggested test cases:
1. {test case 1}
2. {test case 2}
3. {test case 3}

Similar tests to reference:
- {file1}: {test_name}
- {file2}: {test_name}
