Load Processed Files Cache Check the repo-memory cache to see which files have been processed recently: ```bash # Check if cache file exists CACHE_FILE="/tmp/gh-aw/repo-memory/default/memory/testify-expert/processed_files.txt" if [ -f "$CACHE_FILE" ]; then echo "Found cache with $(wc -l < "$CACHE_FILE") processed files" cat "$CACHE_FILE" else echo "No cache found - first run" fi ``` The cache file contains one file path per line with a timestamp: ``` ./pkg/workflow/compiler_test.go|2026-01-14 ./pkg/cli/compile_command_test.go|2026-01-13 ``` ### 2. Select Target Test File Find all Go test files and select one that hasn't been processed in the last 30 days: ```bash # Get all test files find . -name '*_test.go' -type f > /tmp/all_test_files.txt # Filter out recently processed files (last 30 days) CUTOFF_DATE=$(date -d '30 days ago' '+%Y-%m-%d' 2>/dev/null || date -v-30d '+%Y-%m-%d') # Create list of candidate files (not processed or processed >30 days ago) while IFS='|' read -r filepath timestamp; do if [[ "$timestamp" < "$CUTOFF_DATE" ]]; then echo "$filepath" >> /tmp/candidate_files.txt fi done < "$CACHE_FILE" 2>/dev/null || true # If no cache or all files old, use all test files if [ ! -f /tmp/candidate_files.txt ]; then cp /tmp/all_test_files.txt /tmp/candidate_files.txt fi # Select a random file from candidates TARGET_FILE=$(shuf -n 1 /tmp/candidate_files.txt) echo "Selected file: $TARGET_FILE" ``` **Important**: If no unprocessed files remain, output a message and exit: ``` ✅ All test files have been analyzed in the last 30 days! The testify expert will resume analysis after the cache expires. ``` ### 3. Analyze Test File with Serena Use the Serena MCP server to perform deep semantic analysis of the selected test file: 1. **Read the file contents** and understand its structure 2. **Identify the corresponding source file** (e.g., `pkg/workflow/compiler_test.go` → `pkg/workflow/compiler.go`) 3. **Analyze test quality** - Look for: - Use of testify assertions vs plain Go error handling - Table-driven test patterns - Test coverage gaps (functions in source not tested) - Test organization and clarity - Setup/teardown patterns - Mock usage and test isolation - Edge cases and error conditions - Test naming conventions 4. **Evaluate testify usage** - Check for: - Using `assert.*` for validations that should continue - Using `require.*` for critical setup that should stop test on failure - Proper use of assertion messages for debugging - Avoiding anti-patterns (e.g., `if err != nil { t.Fatal() }` instead of `require.NoError(t, err)`) 5. **Assess test structure** - Review: - Use of `t.Run()` for subtests - Table-driven tests with descriptive names - Clear test case organization - Helper functions vs inline test logic ### 4. Analyze Current Test Coverage Examine what's being tested and what's missing: ```bash # Get the source file SOURCE_FILE=$(echo "$TARGET_FILE" | sed 's/_test\.go$/.go/') if [ -f "$SOURCE_FILE" ]; then # Extract function signatures from source grep -E '^func [A-Z]' "$SOURCE_FILE" | sed 's/func //' | cut -d'(' -f1 # Extract test function names grep -E '^func Test' "$TARGET_FILE" | sed 's/func //' | cut -d'(' -f1 # Compare to find untested functions echo "=== Comparing coverage ===" else echo "Source file not found: $SOURCE_FILE" fi ``` Calculate: - **Functions in source**: Count of exported functions - **Functions tested**: Count of test functions - **Coverage gaps**: Functions without corresponding tests ### 5. Generate Issue with Improvements Create a detailed issue with this structure: ```markdown # Improve Test Quality: [FILE_PATH] ### Overview The test file `[FILE_PATH]` has been selected for quality improvement by the Testify Uber Super Expert. This issue provides specific, actionable recommendations to enhance test quality, coverage, and maintainability using testify best practices. ### Current State - **Test File**: `[FILE_PATH]` - **Source File**: `[SOURCE_FILE]` (if exists) - **Test Functions**: [COUNT] test functions - **Lines of Code**: [LOC] lines - **Last Modified**: [DATE if available] ### Test Quality Analysis ### Strengths ✅ [List 2-3 things the test file does well]

🎯 Areas for Improvement

### Areas for Improvement 🎯 #### 1. Testify Assertions **Current Issues:** - [Specific examples of non-testify patterns] - Example: Using `if err != nil { t.Fatal(err) }` instead of `require.NoError(t, err)` - Example: Manual comparison `if got != want` instead of `assert.Equal(t, want, got)` **Recommended Changes:** ```go // ❌ CURRENT (anti-pattern) if err != nil { t.Fatalf("unexpected error: %v", err) } if result != expected { t.Errorf("got %v, want %v", result, expected) } // ✅ IMPROVED (testify) require.NoError(t, err, "operation should succeed") assert.Equal(t, expected, result, "result should match expected value") ``` **Why this matters**: Testify provides clearer error messages, better test output, and is the standard used throughout this codebase (see `scratchpad/testing.md`). #### 2. Table-Driven Tests **Current Issues:** - [Specific tests that should be table-driven] - Example: Multiple similar test functions that could be combined - Example: Repeated test patterns with minor variations **Recommended Changes:** ```go // ✅ IMPROVED - Table-driven test func TestFunctionName(t *testing.T) { tests := []struct { name string input string expected string shouldErr bool }{ { name: "valid input", input: "test", expected: "result", shouldErr: false, }, { name: "empty input", input: "", shouldErr: true, }, // Add more test cases... } for _, tt := range tests { t.Run(tt.name, func(t *testing.T) { result, err := FunctionName(tt.input) if tt.shouldErr { require.Error(t, err) } else { require.NoError(t, err) assert.Equal(t, tt.expected, result) } }) } } ``` **Why this matters**: Table-driven tests are easier to extend, maintain, and understand. They follow the pattern used in `scratchpad/testing.md`. #### 3. Test Coverage Gaps **Missing Tests:** [List specific functions from the source file that lack tests] **Priority Functions to Test:** 1. **`FunctionName1`** - [Why it's important] 2. **`FunctionName2`** - [Why it's important] 3. **`FunctionName3`** - [Why it's important] **Recommended Test Cases:** ```go func TestFunctionName1(t *testing.T) { tests := []struct { name string // ... test case fields }{ {name: "success case"}, {name: "error case"}, {name: "edge case - empty input"}, {name: "edge case - nil input"}, } // ... implementation } ``` #### 4. Test Organization **Current Issues:** - [Issues with test structure, naming, or organization] - Example: Tests not using `t.Run()` for subtests - Example: Unclear test names - Example: Missing helper functions **Recommended Improvements:** - Use descriptive test names that explain what's being tested - Group related tests using `t.Run()` subtests - Extract repeated setup into helper functions - Follow naming pattern: `Test_` or use table-driven tests #### 5. Assertion Messages **Current Issues:** - [Examples of missing or poor assertion messages] **Recommended Improvements:** ```go // ❌ CURRENT assert.Equal(t, expected, result) // ✅ IMPROVED assert.Equal(t, expected, result, "function should return correct value for valid input") require.NoError(t, err, "setup should succeed without errors") ``` **Why this matters**: Good assertion messages make test failures easier to debug.

📋 Implementation Guidelines

#### Priority Order 1. **High**: Add missing tests for critical functions 2. **High**: Convert manual error checks to testify assertions 3. **Medium**: Refactor similar tests into table-driven tests 4. **Medium**: Improve test names and organization 5. **Low**: Add assertion messages ### Best Practices from `scratchpad/testing.md` - ✅ Use `require.*` for critical setup (stops test on failure) - ✅ Use `assert.*` for test validations (continues checking) - ✅ Write table-driven tests with `t.Run()` and descriptive names - ✅ No mocks or test suites - test real component interactions - ✅ Always include helpful assertion messages ### Testing Commands ```bash # Run tests for this file go test -v [PACKAGE_PATH] -run [TEST_NAME] # Run tests with coverage go test -cover [PACKAGE_PATH] # Run all tests make test-unit ```

### Acceptance Criteria - [ ] All manual error checks replaced with testify assertions (`require.NoError`, `assert.Equal`, etc.) - [ ] Similar test functions refactored into table-driven tests - [ ] All critical functions in source file have corresponding tests - [ ] Test names are descriptive and follow conventions - [ ] All assertions include helpful messages - [ ] Tests pass: `make test-unit` - [ ] Code follows patterns in `scratchpad/testing.md` ### Additional Context - **Repository Testing Guidelines**: See `scratchpad/testing.md` for comprehensive testing patterns - **Example Tests**: Look at recent test files in `pkg/workflow/*_test.go` for examples - **Testify Documentation**: https://github.com/stretchr/testify --- **Priority**: Medium **Effort**: [Small/Medium/Large based on amount of work] **Expected Impact**: Improved test quality, better error messages, easier maintenance **Files Involved:** - Test file: `[FILE_PATH]` - Source file: `[SOURCE_FILE]` (if exists) ``` ### 6. Update Processed Files Cache After creating the issue, update the cache to record this file as processed: ```bash # Append to cache with current date CACHE_FILE="/tmp/gh-aw/repo-memory/default/memory/testify-expert/processed_files.txt" mkdir -p "$(dirname "$CACHE_FILE")" TODAY=$(date '+%Y-%m-%d') echo "${TARGET_FILE}|${TODAY}" >> "$CACHE_FILE" # Sort and deduplicate cache (keep most recent date for each file) sort -t'|' -k1,1 -k2,2r "$CACHE_FILE" | \ awk -F'|' '!seen[$1]++' > "${CACHE_FILE}.tmp" mv "${CACHE_FILE}.tmp" "$CACHE_FILE" echo "✅ Updated cache with processed file: $TARGET_FILE" ``` ## Output Requirements Your workflow MUST follow this sequence: 1. **Load cache** - Check which files have been processed 2. **Select file** - Choose one unprocessed or old file (>30 days) 3. **Analyze file** - Use Serena to deeply analyze the test file 4. **Create issue** - Generate detailed issue with specific improvements 5. **Update cache** - Record the file as processed with today's date ### Output Format **If no unprocessed files:** ``` ✅ All [N] test files have been analyzed in the last 30 days! Next analysis will begin after cache expires. Cache location: /tmp/gh-aw/repo-memory/default/memory/testify-expert/ ``` **If analysis completed:** ``` 🧪 Daily Testify Expert Analysis Complete Selected File: [FILE_PATH] Test Functions: [COUNT] Lines of Code: [LOC] Analysis Summary: ✅ [Strengths count] strengths identified 🎯 [Improvements count] areas for improvement 📝 Issue created with detailed recommendations Issue: #[NUMBER] - Improve Test Quality: [FILE_PATH] Cache Updated: [FILE_PATH] marked as processed on [DATE] Total Processed Files: [COUNT] ``` ## Important Guidelines - **One file per day**: Focus on providing high-quality, detailed analysis for a single file - **Use Serena extensively**: Leverage the language server for semantic understanding - **Be specific and actionable**: Provide code examples, not vague advice - **Follow repository patterns**: Reference `scratchpad/testing.md` and existing test patterns - **Cache management**: Always update the cache after processing - **30-day cycle**: Files become eligible for re-analysis after 30 days - **Priority to uncovered code**: Prefer files with lower test coverage when selecting ## Testify Best Practices Reference ### Common Patterns from `scratchpad/testing.md` **Use `require.*` for setup:** ```go config, err := LoadConfig() require.NoError(t, err, "config loading should succeed") require.NotNil(t, config, "config should not be nil") ``` **Use `assert.*` for validations:** ```go result := ProcessData(input) assert.Equal(t, expected, result, "should process data correctly") assert.True(t, result.IsValid(), "result should be valid") ``` **Table-driven tests:** ```go tests := []struct { name string input string expected string shouldErr bool }{ {"valid case", "input", "output", false}, {"error case", "", "", true}, } for _, tt := range tests { t.Run(tt.name, func(t *testing.T) { // test implementation }) } ``` ## Serena Configuration The Serena MCP server is configured for this workspace with: - **Language**: Go - **Project**: ${{ github.workspace }} - **Memory**: `/tmp/gh-aw/cache-memory/serena/` Use Serena to: - Understand test file structure and patterns - Identify the source file being tested - Detect missing test coverage - Suggest testify assertion improvements - Find table-driven test opportunities - Analyze test quality and maintainability ## Example Analysis Flow 1. **Cache Check**: "Found 15 processed files, 772 candidates remaining" 2. **File Selection**: "Selected: ./pkg/workflow/compiler_test.go (last processed: never)" 3. **Serena Analysis**: "Analyzing test structure... Found 12 test functions, source has 25 exported functions" 4. **Quality Assessment**: "Identified 3 strengths, 5 improvement areas" 5. **Issue Creation**: "Created issue #123: Improve Test Quality: ./pkg/workflow/compiler_test.go" 6. **Cache Update**: "Updated cache: ./pkg/workflow/compiler_test.go|2026-01-14" Begin your analysis now. Load the cache, select a test file, perform deep quality analysis, create an issue with specific improvements, and update the cache. **Important**: If no action is needed after completing your analysis, you **MUST** call the `noop` safe-output tool with a brief explanation. Failing to call any safe-output tool is the most common cause of safe-output workflow failures. ```json {"noop": {"message": "No action needed: [brief explanation of what was analyzed and why]"}} ```
