For this example, we will target English Wikipedia at the Beta Cluster. The job runs once every day, but you can also start them manually.

Advantages[edit]

  • You do not have to install anything on your machine.
  • You are probably already familiar with Jenkins.
  • While the tests are running, you can continue using your machine as usual, because everything is happening in Jenkins.
  • Debugging failed tests will be reasonably easy, since you will see logs and screenshots of the test run.
  • It will be reasonable fast. It takes 1-5 minutes for a Jenkins job to run. (As of October 2019.)

Disadvantages[edit]

  • You will need internet connection while running the tests.
  • You might not be familiar with Jenkins, so you will have to learn how to use yet another tool.

Check if the Jenkins job is configured to run for a repository[edit]

  • In mediawiki.yaml look for mediawiki-wdio-selenium project. (As of October 2019.)
