# FRB Testing

> **Note:** Check your user-level `remote-testing` rules before running commands. Tests may require remote execution.

## Overview

Maps change types to local test commands. Tests run on CI by default, so local testing is optional but useful for debugging.

## Quick Reference

| Change Type | Command |
|-------------|---------|
| All Rust packages | `./frb_internal test-rust` |
| `frb_rust/` | `./frb_internal test-rust-package --package frb_rust` |
| `frb_codegen/` | `./frb_internal test-rust-package --package frb_codegen` |
| Specific Rust package | `./frb_internal test-rust-package --package <path>` |
| `frb_dart/` | `./frb_internal test-dart-native --package frb_dart` |
| Dart example | `./frb_internal test-dart-native --package frb_example/<name>` |
| Flutter example | `./frb_internal test-flutter-native --package frb_example/flutter_<name>` |
| Web test | `./frb_internal test-dart-web --package frb_example/<name>` |

## Web Tests

Web tests compile Dart tests to WebAssembly and run in a headless browser.

### Supported Packages
- `frb_dart`
- `frb_example/dart_minimal`
- `frb_example/pure_dart`
- `frb_example/pure_dart_pde`

### Requirements
- `wasm32-unknown-unknown` target: `rustup target add wasm32-unknown-unknown --toolchain nightly-2025-02-01`
- `rust-src` component: `rustup component add rust-src --toolchain nightly-2025-02-01`
- `wasm-pack`: `curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh`
- Chrome/Chromium browser

### Running in Docker
When running web tests in Docker containers, puppeteer needs `--no-sandbox` flag. The test runner auto-detects Docker environment via `/.dockerenv`.

## When to Test Locally

**Run:** Debugging test failure, developing new tests, verifying fix before push

**Skip:** Documentation only, CI will catch it, just checking compilation
