Karma Local WebDriver Launcher - Launches local web browsers using WebDriver, to enable screenshots and other advanced tests to be executed in-browser.
npm install karma-local-wd-launcherKarma Local WebDriver Launcher
Launches local web browsers using WebDriver, to enable screenshots and other
advanced tests to be executed in-browser. If you don't need WebDriver to
enable some test scenario in Karma, you can just use typical local browser
launchers.
Supports Chrome, Firefox, Edge, and Safari.
``sh`
npm install --save-dev karma-local-wd-launcher
This launcher will use the
webdriver-installer
module to automatically download and install driver binaries for your local
browsers. These will be cached in a folder called .webdriver-installer-cache
in your home directory.
Alternately, you may use the environment variables CHROMEDRIVER_PATH,GECKODRIVER_PATH, or SAFARIDRIVER_PATH to indicate where these drivers are
already installed.
`js`
// karma.conf.js
module.exports = (config) => {
config.set({
plugins: ['karma-local-wd-launcher'],
browsers: ['Chrome', 'Firefox', 'Edge', 'Safari'],
});
};
You can give Karma's command-line interface a list of browsers, too:
`sh`
karma start --browsers Chrome Firefox Safari
There is a possibilty to create custom launcher based on existing ones, i.e. to
pass additional configuration options to specific WebDriver.
`js``
// karma.conf.js
module.exports = (config) => {
config.set({
customLaunchers: {
'ChromeNoBackgroundSuspend': {
base: 'Chrome',
config: {
'goog:chromeOptions': {
args: [
'--disable-background-media-suspend',
'--disable-background-timer-throttling',
'--disable-backgrounding-occluded-windows',
],
},
},
},
},
});
};
