# React Native Firebase - Testing Project

## Requirements

* Make sure you have Xcode installed (tested with Xcode 8.1-8.2).
* make sure you have node installed (`brew install node`, node 7.6.0 and up is required.
* Make sure you have react-native dependencies installed:
  * react-native-cli is installed (`npm install -g react-native-cli`)
  * watchman is installed (`brew install watchman`)
  * [appleSimUtils](https://github.com/wix/AppleSimulatorUtils)
  * detox-cli `npm install -g detox-cli`

### Step 1: Npm install

* Run `npm install`.

## To test build of your app

### Step 2: Build

* Build the demo project

```sh
detox build --configuration ios.sim.debug
```

### Step 3: Test

* start react-native packager

```sh
npm run start
```

* Run tests on the demo project

```sh
detox test --configuration ios.sim.debug
```

This action will open a new simulator and run the tests on it.

#### Running specific tests

Mocha supports the `.only` syntax, e.g. instead of `describe(...) || it(...)` you can use `describe.only(...) || it.only(...)` to only run that specific context or test.

Another way to do this is via adding a `--grep` option to e2e/mocha.opts file, e.g. `--grep auth` for all tests that have auth in the file path or tests descriptions.

#### Running Node debugger

Add `--inspect` to e2e/mocha.opts file

To open node debugger tools on chrome navigate to chrome://inspect/#devices and click the `Open dedicated DevTools for Node` link.

Add the default connection of `localhost:9229` if you haven't already - then the debugger will automatically connect everytime you start tests with inspect flag.
