Detox is gray box end-to-end testing and automation library for mobile apps. It has a lot of great features:
|
|
|
|
- Cross Platform
|
|
- Runs on Devices
|
|
- Automatically Synchronized
|
|
- Test Runner Independent
|
|
- Debuggable
|
|
|
|
## Setting Up Detox
|
|
|
|
### Install applesimutils (Mac only)
|
|
|
|
[applesimutils](https://github.com/wix/AppleSimulatorUtils) is a collection of utils for Apple simulators.
|
|
|
|
```sh
|
|
brew tap wix/brew
|
|
brew install applesimutils
|
|
```
|
|
|
|
### Install Jest Globally
|
|
|
|
```sh
|
|
npm install -g jest
|
|
```
|
|
|
|
### Generating Applications
|
|
|
|
By default, when creating a mobile application, Nx will use Detox to create the e2e tests project.
|
|
|
|
```shell
|
|
nx g @nrwl/react-native:app frontend
|
|
```
|
|
|
|
### Creating a Detox E2E project for an existing project
|
|
|
|
You can create a new Detox E2E project for an existing mobile project.
|
|
|
|
If the `@nrwl/detox` package is not installed, install the version that matches your `@nrwl/workspace` version.
|
|
|
|
{% tabs %}
|
|
{%tab label="npm"%}
|
|
|
|
```sh
|
|
# npm
|
|
npm install --save-dev @nrwl/detox
|
|
```
|
|
|
|
{% /tab %}
|
|
{%tab label="yarn"%}
|
|
|
|
```sh
|
|
# yarn
|
|
yarn add --dev @nrwl/detox
|
|
```
|
|
|
|
{% /tab %}
|
|
{% /tabs %}
|
|
|
|
Next, generate an E2E project based on an existing project.
|
|
|
|
```sh
|
|
nx g @nrwl/detox:app your-app-name-e2e --project=your-app-name
|
|
```
|
|
|
|
Replace `your-app-name` with the app's name as defined in your `tsconfig.base.json` file or the `name` property of your `package.json`.
|
|
|
|
In addition, you need to follow [instructions at Detox](https://github.com/wix/Detox/blob/master/docs/Introduction.Android.md) to do manual setup for Android files.
|
|
|
|
## Using Detox
|
|
|
|
### Testing Applications
|
|
|
|
- Run `nx test-ios frontend-e2e` to build the iOS app and execute e2e tests with Detox for iOS (Mac only)
|
|
- Run `nx test-android frontend-e2e` to build the Android app and execute e2e tests with Detox for Android
|
|
|
|
You can run below commands:
|
|
|
|
- `nx build-ios frontend-e2e`: build the iOS app (Mac only)
|
|
- `nx build-android frontend-e2e`: build the Android app
|
|
|
|
### Testing against Prod Build
|
|
|
|
You can run your e2e test against a production build:
|
|
|
|
- `nx test-ios frontend-e2e --prod`: to build the iOS app and execute e2e tests with Detox for iOS with Release configuration (Mac only)
|
|
- `nx test-android frontend-e2e`: rto build the Android app and execute e2e tests with Detox for Android with release build type
|
|
- `nx build-ios frontend-e2e --prod`: build the iOS app using Release configuration (Mac only)
|
|
- `nx build-android frontend-e2e --prod`: build the Android app using release build type
|
|
|
|
## Configuration
|
|
|
|
### Using .detoxrc.json
|
|
|
|
If you need to fine tune your Detox setup, you can do so by modifying `.detoxrc.json` in the e2e project.
|
|
|
|
#### Change Testing Simulator/Emulator
|
|
|
|
For iOS, in terminal, run `xcrun simctl list` to view a list of simulators on your Mac. To open your active simulator, `run open -a simulator`. In `frontend-e2e/.detoxrc.json`, you could change the simulator under `devices.simulator.device`.
|
|
|
|
For Android, in terminal, run `emulator -list-avds` to view a list of emulators installed. To open your emulator, run `emulator -avd <your emulator name>`. In `frontend-e2e/.detoxrc.json`, you could change the simulator under `devices.emulator.device`.
|
|
|
|
In addition, to override the device name specified in a configuration, you could use `--device-name` option: `nx test-ios <app-name-e2e> --device-name "iPhone 11"`. The `device-name` property provides you the ability to test an application run on specific device.
|
|
|
|
```shell
|
|
nx test-ios frontend-e2e --device-name "iPhone 11"
|
|
nx test-android frontend-e2e --device-name "Pixel_4a_API_30"
|
|
```
