## Description

Run GDScript test suites from the command line with `godot --headless`, using a SceneTree/MainLoop runner script that exits non-zero on failure so CI can gate merges. Use when a Godot project needs unit tests without opening the editor, when wiring a CI job (GitHub Actions or similar) that must fail the build on a failing `.gd` test, or when a `godot --headless` invocation hangs, opens a window, or exits 0 despite failed assertions.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Godot GDScript headless testing (4.x)

Run GDScript tests from the command line, without the editor GUI, and get a real
process exit code CI can act on. Targets **Godot 4.7** headless CLI.

## When to use

- Use when a Godot project has no testing addon installed and needs a fast way to
  verify GDScript logic (pure functions, resource loading, autoload state) from a
  terminal or CI pipeline.
- Use when wiring a CI job that must fail the build when a `.gd` test fails.
- Use when debugging why a `godot --headless` invocation hangs, opens a window, or
  exits 0 despite failing assertions.

**When *not* to use:** GDScript syntax or language features themselves →
`godot-gdscript`; export/build pipeline and platform templates → `godot-export`
(its own `--headless` use case, producing a binary, not running tests).
