.test.js, .spec.js, __tests__/*.js files → JavaScript/Jest + - _test.py, test_*.py, tests/*.py files → Python/pytest or unittest + - *_test.go, *_test.go files → Go/go-test + - *.test.ts, *.spec.ts files → TypeScript/Jest + + b) Check for configuration files: + - package.json with "jest" dependency → Jest + - pytest.ini, setup.cfg, pyproject.toml → pytest + - go.mod → go test + - unittest imports in test files → Python unittest + + c) Report the detected framework with confidence level + Example: "Detected: pytest (high confidence -

Find all test files matching the detected/specified framework + - Count total number of test files and individual test cases + - Calculate ratio: lines of test code vs lines of application code + - List the main test directories found + + b) Coverage Data Collection: + - Look for coverage reports in common locations: + * Python: .coverage, coverage.xml, htmlcov/, .coverage.* + * JavaScript: coverage/, coverage.json, coverage-final.json + * Go: coverage.out, coverage.html + - If coverage reports exist, parse them to get: + * Overall coverage percentage + * Per-file coverage breakdown + * Uncovered line numbers + - If NO coverage reports found: + * Estimate coverage by analyzing test file imports and function calls + * Identify source files that have no corresponding test files + * Note: "No coverage data found - will identify gaps by analysis" + + c) Gap Analysis: + - Compare current coverage to target {{ coverage_threshold }}% + - Identify files with coverage below threshold + - List top 10 files/modules with lowest coverage + - Focus analysis on {{ focus_areas }} + - Prioritize gaps by impact: + * Critical: Core business logic with <50% coverage + * High: Error handling and edge cases with <70% coverage + * Medium: Helper functions and utilities with <80% coverage + + + # ========================================================================= + # STEP 4: IDENTIFY GAPS USING LEARNED PATTERNS + # ========================================================================= + # Purpose: Use Memory's patterns to make smarter gap identification + # Extension: Both (Developer analysis + Memory context) + + Step 4: Identify Testing Gaps (Using Learned Patterns) + Using both the coverage analysis AND the learned patterns from Step 1: + + a) Apply learned patterns to current analysis: + - If Memory contains testing style preferences, apply them + - Check if current gaps match previously identified gap patterns + - Consider team's preferred test granularity (unit vs integration) + - Note patterns like: "Team prefers testing error cases separately" + + b) Categorize and prioritize missing tests by {{ focus_areas }}: + {% if focus_areas == "all" or "core-logic" in focus_areas %} + -

Write a clear, descriptive test name following framework conventions + - Explain what this test should verify + - Provide the expected test structure for {{ test_framework }} + - Include a brief code example showing the test skeleton + - If learned patterns exist, match the team's testing style + + Example format: + ``` + Test: test_user_authentication_with_invalid_credentials + Purpose: Verify that authentication fails gracefully with wrong password + Priority: Critical (core-logic, error-handling) + Estimated effort: 10 minutes + + Code example for {{ test_framework }}: + [Framework-specific test code here] + ``` + + b) Include implementation context: + - Why this test is important (coverage gap, risk mitigation) + - Which code path it covers + - Expected assertions and edge cases to test + - Dependencies or mocks needed + + c) Organize suggestions by priority: + - Critical (must-have for {{ coverage_threshold }}% target) + - High (important for robust coverage) + - Medium (nice-to-have, improves confidence) + + d) Limit initial suggestions: + - Provide top 5-10 most impactful tests + - Note: "Implement these first, then re-run for more suggestions" + + + # ========================================================================= + # STEP 6: CREATE TEST TEMPLATES (Optional) + # ========================================================================= + # Purpose: Generate ready-to-use test file templates + # Extension: Developer (template creation) + + Step 6: Generate Test Templates + {% if generate_templates == "true" %} + Create test file templates that developers can immediately use: + + a) For files with NO existing tests: + - Create a complete new test file template + - Include proper imports for {{ test_framework }} + - Add setup/teardown methods if applicable + - Provide 2-3 example test functions with placeholders + - Match the coding style from Memory if available + + b) For files with SOME existing tests: + - Generate test functions to add to existing test files + - Match the existing test file's style and structure + - Include comments indicating where to insert the new tests + + c) Include in templates: + - Proper test file naming (matching framework conventions) + - Required imports and dependencies + - Mock/fixture setup if needed + - Clear TODOs for values to fill in + - Example assertions showing expected patterns + + d) Output format: + - Provide templates as copyable code blocks + - Include file paths where templates should be saved + - Add instructions for running the tests + + Example output: + ``` + # File: tests/test_user_authentication.py + # Framework: pytest + # Purpose: Tests for user authentication module + + import pytest + from myapp.auth import authenticate_user + + def test_authentication_success(): + # TODO: Replace with actual test data + user = {"username": "test_user", "password": "correct_password"} + result = authenticate_user(user) + assert result.success is True + assert result.user_id is not None + + def test_authentication_invalid_password(): + # Test critical error path + user = {"username": "test_user", "password": "wrong_password"} + result = authenticate_user(user) + assert result.success is False + assert result.error == "Invalid credentials" + ``` + {% else %} + Template generation is disabled.
