Dig Dug is a simple abstraction library for downloading and launching WebDriver service tunnels and interacting with the REST APIs of these services.
The following services are currently supported:
In many cases, the only configuration you'll need to do to create a tunnel is provide authentication data. This can be provided by setting properties on tunnels or via environment variables. The tunnels use the following environment variables:
| Tunnel class | Environment variables |
|---|---|
BrowserStackTunnel |
BROWSERSTACK_USERNAME, BROWSERSTACK_ACCESS_KEY |
SauceLabsTunnel |
SAUCE_USERNAME, SAUCE_ACCESS_KEY |
TestingBotTunnel |
TESTINGBOT_KEY, TESTINGBOT_SECRET |
Other properties, such as the local port the tunnel should serve on or the URL of a proxy server the tunnel should go through, can be passed to a tunnel constructor or set on a tunnel instance. See the pages for Tunnel and the tunnel subclasses for available properties.
To create a new tunnel, import the desired tunnel class, create a new instance, and call its start method. start returns a Promise that resolves when the tunnel has successfully started. For example, to create a new Sauce Labs tunnel:
var SauceLabsTunnel = require('digdug/SauceLabsTunnel');
var tunnel = new SauceLabsTunnel();
tunnel.start().then(function () {
// interact with the WebDriver server at tunnel.clientUrl
});Once a tunnel has been started, a test runner interacts with it as described in the service's documentation. The Sauce Labs and TestingBot executables start a WebDriver server on localhost that the test client communicates with. To interact with BrowserStack, a test client will connect to hub.browserstack.com after the tunnel has started.
The tunnel classes also provide a sendJobState convenience method to let the remote service know whether a test session passed or failed. This method accepts a session ID and an object containing service-specific data, and it returns a Promise that resolves if the job state was successfully updated.
tunnel.sendJobState(sessionId, { success: true });When testing is finished, call the tunnel's stop method to cleanly shut it down. This method returns a Promise that is resolved when the service tunnel executable has exited.
tunnel.stop().then(function () {
// the tunnel has been shut down
