# @appium/plugin-test-support
> Testing utilities for [Appium](https://appium.io) plugins
This package is for plugin authors to help test their plugins.
[Mocha](https://mochajs.org) is the supported test framework (but can theoretically be used with others).
## Usage
### For E2E Tests
The `pluginE2EHarness` method configures a server and driver for testing via "before all" and "after all"-style hooks.
This example uses [WebdriverIO](https://webdriver.io) to communicate with a test Appium server.
```js
import {pluginE2EHarness} from '@appium/plugin-test-support';
import {remote} from 'webdriverio';
describe('MyPlugin', function() {
pluginE2EHarness({
before: global.before, // from mocha
after: global.after, // from mocha
serverArgs: SOME_EXTRA_SERVER_ARGS,
port: 31337,
host: '127.0.0.1',
appiumHome: process.env.APPIUM_HOME, // best practice: use a temp dir instead
driverName: 'fake', // driver to test with
driverSource: 'local', // use "local" unless you want appium to install from npm every time
driverSpec: FAKE_DRIVER_DIR, // path to local driver working copy or installation
pluginName: 'MyPlugin', // your plugin
pluginSource: 'local', // use "local" for this
pluginSpec: THIS_PLUGIN_DIR, // dir of this plugin's `package.json`
});
it('should use my plugin', async function() {
// at this point, the Appium server will be running with the plugin/driver combination of your
// choosing
// port/host should match what you provided to `pluginE2EHarness`
const browser = await remote({port: 31337, hostname: '127.0.0.1'});
})
});
```
