WebdriverIO Selenium Standalone Service
Handling the Selenium server is out of scope of the actual WebdriverIO project. This service helps you to run Selenium seamlessly when running tests with the WDIO testrunner. It uses the well known selenium-standalone NPM package that automatically sets up the standalone server and all required driver for you.
Note: If you use this service you don't need any other driver services (e.g. wdio-chromedriver-service) anymore. All local browser can be started using this service.
Installation
Before starting make sure you have JDK installed.
The easiest way is to keep @wdio/selenium-standalone-service
as a devDependency in your package.json
.
{
"devDependencies": {
"@wdio/selenium-standalone-service": "^7.7.4"
}
}
You can simple do it by:
npm install @wdio/selenium-standalone-service --save-dev
Instructions on how to install WebdriverIO
can be found here.
Configuration
By default, ChromeDriver, geckodriver and some other browser drivers based on the OS are available when installed on the host system. In order to use the service you need to add selenium-standalone
to your service array:
/**
* simplified mode (available since v6.11.0)
* set `true` to use the version provided by `selenium-standalone`, 'latest' by default
*/
exports.config
// ...
services: [
['selenium-standalone', { drivers: { firefox: '0.29.1', chrome: true, chromiumedge: 'latest' } }]
],
// ...
};
Control browser driver installation/running separately.
// wdio.conf.js
const drivers = {
chrome: { version: '91.0.4472.101' }, // https://chromedriver.chromium.org/
firefox: { version: '0.29.1' }, // https://github.com/mozilla/geckodriver/releases
chromiumedge: { version: '85.0.564.70' } // https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
}
exports.config
// ...
services: [
['selenium-standalone', {
logPath: 'logs',
installArgs: { drivers }, // drivers to install
args: { drivers } // drivers to use
}]
],
// ...
};
Custom Configurations
By default the service starts on localhost:4444
and ensures that all capabilities are able to connect to it. If you prefer to run on a different port please specify port
as an option in your capabilities, e.g.:
// wdio.conf.js
exports.config
// ...
services: [
['selenium-standalone', {
logPath: './temp',
args: {
version: "3.141.59",
seleniumArgs: ['-host', '127.0.0.1','-port', '5555']
},
}]
],
capabilities: [{
browserName: 'chrome',
port: 5555
}, {
browserName: 'firefox',
port: 5555
}, {
browserName: 'MicrosoftEdge',
port: 5555
}]
// ...
}
