  name: karmaExecuteTests
  description: Executes the Karma test runner
  longDescription: |
    In this step the ([Karma test runner](http://karma-runner.github.io)) is executed.

    The step is using the `seleniumExecuteTest` step to spin up two containers in a Docker network:

    * a Selenium/Chrome container (`selenium/standalone-chrome`)
    * a NodeJS container (`node:lts-stretch`)

    In the Docker network, the containers can be referenced by the values provided in `dockerName` and `sidecarName`, the default values are `karma` and `selenium`. These values must be used in the `hostname` properties of the test configuration ([Karma](https://karma-runner.github.io/1.0/config/configuration-file.html) and [WebDriver](https://github.com/karma-runner/karma-webdriver-launcher#usage)).

    !!! note
        In a Kubernetes environment, the containers both need to be referenced with `localhost`.
