 All tests are located alongside source code in the `src/core/` package. Tests follow Go conventions with `*_test.go` filename patterns.
 
+## Running Tests
+
+### Using the test scripts
+
+The repository provides convenience scripts to run all tests with static analysis:
+
+**Unix/Linux/macOS:**
+```bash
+./scripts/test.sh
+```
+
+**Windows:**
+```bash
+scripts\test.bat
+```
+
+Both scripts run:
+1. `go vet ./...` — static analysis for common errors and suspicious code patterns
+2. `go test -race ./...` — tests with race condition detection enabled
+
+### Manual test commands
+
+Run all tests:
+```bash
+go test ./...
+```
+
+Run all tests with race detection:
+```bash
+go test -race ./...
+```
+
+Run tests with verbose output:
+```bash
+go test -v ./...
+```
+
+Run a specific test by name:
+```bash
+go test -run TestRunJobWritesLogFile ./src/core
+```
+
+Run tests with code coverage:
+```bash
+go test -cover ./src/core
+go test -coverprofile=coverage.out ./src/core
+go tool cover -html=coverage.out
+```

 ## Test Design Principles
 
 1. **Isolation** — Tests use `t.TempDir()` for file operations and `t.Setenv()` for environment variables to avoid affecting system state.
