Use as a dependency

To install this as a dependency: npm install -D webdriver-manager. The
following is an example running webdriver-manager as a dependency.
The test downloads the providers and starts the selenium server standalone as
detached. After the test, it will shutdown the selenium server standalone.

``
import {
Options,
setLogLevel,
shutdown,
start,
update,
} from 'webdriver-manager';

const options: Options = {
browserDrivers: [{
name: 'chromedriver' // For browser drivers, we just need to use a valid
// browser driver name. Other possible values
// include 'geckodriver' and 'iedriver'.
}],
server: {
name: 'selenium',
runAsNode: true, // If we want to run as a node. By default
// running as detached will set this to true.
runAsDetach: true // To run this in detached. This returns the
// process back to the parent process.
}
};
setLogLevel('info'); // Required if we webdriver-manager to log to
// console. Not setting this will hide the logs.

describe('some web test', () => {
beforeAll(async () => {
await update(options);
await start(options);
});

it('should run some web test', async () => {
// Your async / await web test with some framework.
});

afterAll(async () => {
await shutdown(options); // Makes the web request to shutdown the server.
// If we do not call shutdown, the java command
// will still be running the server on port 4444.
});
});

`

Use as a command line interface

`
npm i -g webdriver-manager

webdriver-manager update // Downloads the latest binaries.
webdriver-manager start // Starts the selenium server standalone.
`

Note: Installing globally will not work with Protractor if you are trying to
start a Selenium Standalone server with a "local" or "directConnect". It will
not work for these since Protractor is looking files downloaded locally to
the project.
