+### Test Case Information
+The Go test cases are located throughout the repository:
+- **Command tests**: `./cmd/gh-aw/*_test.go` - CLI command and main entry point tests
+- **Workflow tests**: `./pkg/workflow/*_test.go` - Workflow compilation, validation, and execution tests
+- **CLI tests**: `./pkg/cli/*_test.go` - Command implementation tests
+- **Parser tests**: `./pkg/parser/*_test.go` - Frontmatter and schema parsing tests
+- **Campaign tests**: `./pkg/campaign/*_test.go` - Campaign specification tests
+- **Other package tests**: Various `./pkg/*/test.go` files throughout the codebase
+
+The `/tmp/gh-aw/test-results.json` file contains detailed timing and performance data for each test case in JSON format, allowing you to identify slow tests, flaky tests, and optimization opportunities.
 
 ### Environment Setup
 The workflow has already completed:
 - ✅ **Linting**: Dev dependencies installed, linters run successfully
 - ✅ **Building**: Code built with `make build`, lock files compiled with `make recompile`
-- ✅ **Testing**: Unit tests and JavaScript tests run successfully
+- ✅ **Testing**: Unit tests run (with performance data collected in JSON format)
