Getting Started

WebdriverIO comes with its own test runner to help you getting started with integration testing as quickly as possible. All the fiddling around hooking up WebdriverIO with a test framework belongs to the past. The WebdriverIO runner does all the work for you and helps you to run your tests as efficient as possible.

Sweet! Now you need to define a configuration file where all information about your tests, capabilities and settings are set. Switch over to the Configuration File section to find out how that file should look like. With the wdio configuration helper it is super easy to generate your config file. Just run:

1
$ ./node_modules/.bin/wdio config

and it launches the helper utility. It will ask you questions depending on the answers you give. This way you can generate your config file in less than a minute.

WDIO configuration utility

Once you have your configuration file set up you can start your integration tests by calling:

1
$ ./node_modules/.bin/wdio wdio.conf.js

That’s it! Now, you can access to the selenium instance via global variable browser.
