## Appium

**Extends Webdriver**

Appium helper extends [Webriver][1] helper.
 It supports all browser methods and also includes special methods for mobile apps testing.
 You can use this helper to test Web on desktop and mobile devices and mobile apps.

## Appium Installation

Appium is an open source test automation framework for use with native, hybrid and mobile web apps that implements the WebDriver protocol.
It allows you to run Selenium tests on mobile devices and also test native, hybrid and mobile web apps.

Download and install [Appium][2]

```sh
npm install -g appium
```

Launch the daemon: `appium`

## Helper configuration

This helper should be configured in codecept.json or codecept.conf.js

-   `app`: Application path. Local path or remote URL to an .ipa or .apk file, or a .zip containing one of these. Alias to desiredCapabilities.appPackage
-   `host`: (default: 'localhost') Appium host
-   `port`: (default: '4723') Appium port
-   `platform`: (Android or IOS), which mobile OS to use; alias to desiredCapabilities.platformName
-   `restart`: restart browser or app between tests (default: true), if set to false cookies will be cleaned but browser window will be kept and for apps nothing will be changed.
-   `desiredCapabilities`: \[], Appium capabilities, see below
    -   `platformName` - Which mobile OS platform to use
    -   `appPackage` - Java package of the Android app you want to run
    -   `appActivity` - Activity name for the Android activity you want to launch from your package.
    -   `deviceName`: The kind of mobile device or emulator to use
    -   `platformVersion`: Mobile OS version
    -   `app` - The absolute local path or remote http URL to an .ipa or .apk file, or a .zip containing one of these. Appium will attempt to install this app binary on the appropriate device first.
    -   `browserName`: Name of mobile web browser to automate. Should be an empty string if automating an app instead.

Example Android App:

```js
{
  helpers: {
      Appium: {
          platform: "Android",
          desiredCapabilities: {
              appPackage: "com.example.android.myApp",
              appActivity: "MainActivity",
              deviceName: "OnePlus3",
              platformVersion: "6.0.1"
          }
      }
    }
}
```

Example iOS Mobile Web with local Appium:

```js
{
helpers: {
  Appium: {
    platform: "iOS",
    url: "https://the-internet.herokuapp.com/",
    desiredCapabilities: {
      deviceName: "iPhone X",
      platformVersion: "12.0",
      browserName: "safari"
    }
  }
}
}
```

Example iOS Mobile Web on BrowserStack:

```js
{
helpers: {
  Appium: {
    host: "hub-cloud.browserstack.com",
    port: 4444,
    user: process.env.BROWSERSTACK_USER,
    key: process.env.BROWSERSTACK_KEY,
    platform: "iOS",
    url: "https://the-internet.herokuapp.com/",
    desiredCapabilities: {
      realMobile: "true",
      device: "iPhone 8",
      os_version: "12",
      browserName: "safari"
    }
  }
}
}
```
