GDScript Test

GDScript Test

Run GDUnit4 tests using the test wrapper script.

When to Use

• After implementing new features
• After fixing bugs
• After modifying GDScript files
• When you need to verify test coverage
• When running CI/​CD validation locally

Test Execution

Run tests using the wrapper script included in this skill.

Run All Tests

${CLAUDE_PLUGIN_ROOT}/​skills/​gdunit4-test-runner/​scripts/​run_test.sh

Scans entire project for tests.

Run Specific Test File

${CLAUDE_PLUGIN_ROOT}/​skills/​gdunit4-test-runner/​scripts/​run_test.sh tests/​test_foo.gd

Run Multiple Tests

${CLAUDE_PLUGIN_ROOT}/​skills/​gdunit4-test-runner/​scripts/​run_test.sh tests/​test_foo.gd tests/​test_bar.gd

Run Tests in Directory

${CLAUDE_PLUGIN_ROOT}/​skills/​gdunit4-test-runner/​scripts/​run_test.sh tests/​application/

Verbose Mode

${CLAUDE_PLUGIN_ROOT}/​skills/​gdunit4-test-runner/​scripts/​run_test.sh -v

Shows all Godot logs (useful for debugging test issues).

Understanding Results

The script outputs test results in JSON format for easy parsing.

Success

{
  "summary": {
    "total": 186,
    "passed": 186,
    "failed": 0,
    "crashed": false,
    "status": "passed"
  },
  "failures": []
}

Failure

{
  "summary": {
    "total": 10,
    "passed": 8,
    "failed": 2,
    "crashed": false,
    "status": "failed"
  },
  "failures": [
    {
      "class": "TestClassName",
      "method": "test_method_name",
      "file": "res://tests/​test_file.gd",
      "line": 42,
      "expected": "expected_value",
      "actual": "actual_value",
      "message": "FAILED: res://tests/​test_file.gd:42"
    }
  ]
}

Crash

{
  "summary": {
    "total": 5,
    "passed": 3,
    "failed": 0,
    "crashed": true,
    "status": "crashed"
  },
  "crash_details": {
    "crash_info": "handle_crash: Program crashed with signal 11\n...",
    "script_errors": "SCRIPT ERROR: Parse Error: ...\n...",
    "engine_errors": "ERROR: Failed to load script ...\n..."
  },
  "failures": []
}

Godot crashed during test execution. Only tests completed before crash are reported.

The crash_details object includes:

• crash_info: Crash signal and C++ backtrace (if available)
• script_errors: GDScript parse errors with file paths and line numbers
• engine_errors: Engine-level errors (resource loading failures, etc.)

Exit Codes

• 0: All tests passed
• 1: Some tests failed
• 2: Crash or error (e.g., Godot crashed, report file not found)

Notes

• Script automatically changes to project root before running tests
• Test reports are saved in reports/ directory
• Uses gdUnit4 framework (configured in project.godot)
• Compatible with CI/​CD environments
