## What it does

\`test-macos-app` works out whether the project should use `xcodebuild test` or `swift test`, then runs the smallest useful test scope. A supplied `target` or `filter` narrows the run instead of invoking the whole suite. The command also accepts an Xcode scheme, a test target or product, and either `Debug` or `Release` configuration.

Failures are sorted into compile errors, failed assertions, crashes, environment or setup problems, and flaky tests. The result calls out the main blocker and the narrowest sensible follow-up. A focused rerun takes priority when the available arguments make one possible.

The workflow also checks for host app setup and simulator-only assumptions that can interfere with a macOS run. When `target` or `filter` is present, rerunning the complete suite is unnecessary.

## Install

### Codex (native platform)

**Manually: put the files in place**
- File: `~/.codex/prompts/test-macos-app.md` — Call it with /prompts:test-macos-app. Codex marks this format deprecated in favour of skills

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/test-macos-app.md` — Call it with /test-macos-app. For all projects use ~/.claude/commands/

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/test-macos-app.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/test-macos-app.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

## When to use it
- run macOS tests with `xcodebuild test` or `swift test`
- narrow execution to a scheme, target, or filter
- separate build errors from test failures
- classify crashes and environment problems
- identify the main blocker and next step

## Example prompts
- Run `/test-macos-app` and check the smallest useful macOS scope.
- Use `/test-macos-app target=MyMacTests` to focus on the `MyMacTests` target.
- Run the `LoginTests` filter under `Release` with `/test-macos-app filter=LoginTests configuration=Release`.

BEGIN THIRD-PARTY FILE 67264de6fed643d5
```text
# /test-macos-app

Run the smallest meaningful macOS test scope first and explain failures by category.

## Arguments

- `scheme`: Xcode scheme name (optional)
- `target`: test target or product name (optional)
- `filter`: test filter expression (optional)
- `configuration`: `Debug` or `Release` (optional, default: `Debug`)

## Workflow

1. Detect whether the repo uses `xcodebuild test` or `swift test`.
2. Prefer focused test execution when a target or filter is provided.
3. Classify failures as compile, assertion, crash, env/setup, or flake.
4. Summarize the top blocker and the narrowest sensible next step.

## Guardrails

- Avoid rerunning the full suite if a focused rerun is possible.
- Distinguish build failures from actual failing tests.
- Note when host app setup or simulator-only test assumptions leak into a macOS run.
