karmaExecuteTests¶
Executes the Karma test runner
Please note that Karma is marked as DEPRECATED as of 04/2023. There is no migration path defined yet.
Description¶
In this step the (Karma test runner) 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-buster)
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 and WebDriver).
Note
In a Kubernetes environment, the containers both need to be referenced with localhost.
Usage¶
We recommend to define values of step parameters via .pipeline/config.yml file.
In this case, calling the step is essentially reduced to defining the step name.
Calling the step can be done either in an orchestrator specific way (e.g. via a Jenkins library step) or on the command line.
