## WebDriver
**Extends Helper**
WebDriver helper which wraps [webdriverio][1] library to
manipulate browser using Selenium WebDriver or PhantomJS.
WebDriver requires Selenium Server and ChromeDriver/GeckoDriver to be installed. Those tools can be easily installed via NPM. Please check [Testing with WebDriver][2] for more details.
### Configuration
This helper should be configured in codecept.json or codecept.conf.js
- `url`: base url of website to be tested.
- `basicAuth`: (optional) the basic authentication to pass to base url. Example: {username: 'username', password: 'password'}
- `browser`: browser in which to perform testing.
- `host`: - WebDriver host to connect.
- `port`: - WebDriver port to connect.
- `protocol`: - protocol for WebDriver server.
- `path`: - path to WebDriver server,
- `restart`: - restart browser between tests.
- `smartWait`: (optional) **enables [SmartWait][3]**; wait for additional milliseconds for element to appear. Enable for 5 secs: "smartWait": 5000.
- `disableScreenshots`: - don't save screenshots on failure.
- `fullPageScreenshots` - make full page screenshots on failure.
- `uniqueScreenshotNames`: - option to prevent screenshot override if you have scenarios with the same name in different suites.
- `keepBrowserState`: - keep browser state between tests when `restart` is set to false.
- `keepCookies`: - keep cookies between tests when `restart` set to false.
- `windowSize`: (optional) default window size. Set to `maximize` or a dimension in the format `640x480`.
- `waitForTimeout`: sets default wait time in _ms_ for all `wait*` functions.
- `desiredCapabilities`: Selenium's [desired
capabilities][4].
- `manualStart`: - do not start browser before a test, start it manually inside a helper
with `this.helpers["WebDriver"]._startBrowser()`.
- `timeouts`: [WebDriver timeouts][5] defined as hash.
Example:
```js
{
helpers: {
WebDriver : {
smartWait: 5000,
browser: "chrome",
restart: false,
windowSize: "maximize",
timeouts: {
"script": 60000,
"page load": 10000
}
}
}
}
```
Example with basic authentication
```js
{
helpers: {
WebDriver : {
smartWait: 5000,
browser: "chrome",
basicAuth: {username: 'username', password: 'password'},
restart: false,
windowSize: "maximize",
timeouts: {
"script": 60000,
"page load": 10000
}
}
}
}
```
Additional configuration params can be used from [webdriverio
website][6].
### Headless Chrome
```js
{
helpers: {
WebDriver : {
url: "http://localhost",
browser: "chrome",
desiredCapabilities: {
chromeOptions: {
args: [ "--headless", "--disable-gpu", "--no-sandbox" ]
}
}
}
}
}
```
### Internet Explorer
Additional configuration params can be used from [IE options][7]
```js
{
helpers: {
WebDriver : {
url: "http://localhost",
browser: "internet explorer",
desiredCapabilities: {
ieOptions: {
"ie.browserCommandLineSwitches": "-private",
"ie.usePerProcessProxy": true,
"ie.ensureCleanSession": true,
}
}
}
}
}
```
### Selenoid Options
[Selenoid][8] is a modern way to run Selenium inside Docker containers.
Selenoid is easy to set up and provides more features than original Selenium Server. Use `selenoidOptions` to set Selenoid capabilities
```js
{
helpers: {
WebDriver : {
url: "http://localhost",
browser: "chrome",
desiredCapabilities: {
selenoidOptions: {
enableVNC: true,
}
}
}
}
}
```
### Connect Through proxy
CodeceptJS also provides flexible options when you want to execute tests to Selenium servers through proxy. You will
need to update the `helpers.WebDriver.capabilities.proxy` key.
```js
{
helpers: {
WebDriver: {
capabilities: {
proxy: {
"proxyType": "manual|pac",
"proxyAutoconfigUrl": "URL TO PAC FILE",
"httpProxy": "PROXY SERVER",
"sslProxy": "PROXY SERVER",
"ftpProxy": "PROXY SERVER",
"socksProxy": "PROXY SERVER",
"socksUsername": "USERNAME",
"socksPassword": "PASSWORD",
"noProxy": "BYPASS ADDRESSES"
}
}
}
}
}
```
For example,
```js
{
helpers: {
WebDriver: {
capabilities: {
proxy: {
"proxyType": "manual",
"httpProxy": "http://corporate.proxy:8080",
"socksUsername": "codeceptjs",
"socksPassword": "secret",
"noProxy": "127.0.0.1,localhost"
}
}
}
}
}
```
Please refer to [Selenium - Proxy Object][4] for more
information.
### Cloud Providers
WebDriver makes it possible to execute tests against services like `Sauce Labs` `BrowserStack` `TestingBot`
Check out their documentation on [available parameters][9]
Connecting to `BrowserStack` and `Sauce Labs` is simple. All you need to do
is set the `user` and `key` parameters. WebDriver automatically know which
service provider to connect to.
```js
{
helpers:{
WebDriver: {
url: "YOUR_DESIRED_HOST",
user: "YOUR_BROWSERSTACK_USER",
key: "YOUR_BROWSERSTACK_KEY",
capabilities: {
"browserName": "chrome",
// only set this if you're using BrowserStackLocal to test a local domain
// "browserstack.local": true,
// set this option to tell browserstack to provide addition debugging info
// "browserstack.debug": true,
}
}
}
}
```
#### SauceLabs
SauceLabs can be configured via wdio service, which should be installed additionally:
npm i @wdio/sauce-service --save
It is important to make sure it is compatible with current webdriverio version.
Enable `wdio` plugin in plugins list and add `sauce` service:
```js
plugins: {
wdio: {
enabled: true,
services: ['sauce'],
user: ... ,// saucelabs username
key: ... // saucelabs api key
// additional config, from sauce service
}
}
```
See [complete reference on webdriver.io][10].
> Alternatively, use [codeceptjs-saucehelper][11] for better reporting.
#### BrowserStack
BrowserStack can be configured via wdio service, which should be installed additionally:
npm i @wdio/browserstack-service --save
It is important to make sure it is compatible with current webdriverio version.
Enable `wdio` plugin in plugins list and add `browserstack` service:
```js
plugins: {
wdio: {
enabled: true,
services: ['browserstack'],
user: ... ,// browserstack username
key: ... // browserstack api key
// additional config, from browserstack service
}
}
```
See [complete reference on webdriver.io][12].
> Alternatively, use [codeceptjs-bshelper][13] for better reporting.
#### TestingBot
> **Recommended**: use official [TestingBot Helper][14].
Alternatively, TestingBot can be configured via wdio service, which should be installed additionally:
npm i @wdio/testingbot-service --save
It is important to make sure it is compatible with current webdriverio version.
Enable `wdio` plugin in plugins list and add `testingbot` service:
```js
plugins: {
wdio: {
enabled: true,
services: ['testingbot'],
user: ... ,// testingbot key
key: ... // testingbot secret
// additional config, from testingbot service
}
}
```
See [complete reference on webdriver.io][15].
#### Applitools
Visual testing via Applitools service
> Use [CodeceptJS Applitools Helper][16] with Applitools wdio service.

I.executeScript(function() {
// now we are inside browser context
$('date').datetimepicker('setDate', new Date());
});
```
Can return values. Don't forget to use `await` to get them.
```js
