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:8-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` + "`" + `.`,
