GDScript Test

Run GDUnit4 tests using the gdunit4-test-runner binary.

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

Setup

Before running tests, ensure the binary is installed:

1. Check if bin/gdunit4-test-runner exists in the skill directory
2. If not, run the install script:

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

Test Execution

Run tests using the binary directly.

NEVER use addons/gdUnit4/runtest.sh or direct godot commands.

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

Notes

• Binary 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
• Binary handles Godot existence check and error handling internally
