Continuous ATDD on K8s

Continuous ATDD on K8s using the Geb Framework and Selenium Hub.

Usage

First, we need to deploy the required Selenium infrastructure to K8s. The Selenium hub is required, and also at least one browser node.

# deploy the Selenium hub to connect to
$ kubectl create ns selenium-hub
$ kubectl apply -f src/test/kubernetes/selenium-hub.yaml -n selenium-hub

# either deploy Chrome or Firefox or both (if you have enough memory)
$ kubectl apply -f src/test/kubernetes/selenium-node-chrome.yaml -n selenium-hub
$ kubectl apply -f src/test/kubernetes/selenium-node-firefox.yaml -n selenium-hub

# use port forwarding to Selenium Hub for local execution
$ kubectl port-forward service/selenium-hub 4444 -n selenium-hub

Next, we can run the Geb UI tests using either local or remote browsers.

$ ./gradlew testClasses

$ ./gradlew chromeTest          # local Chrome with UI
$ ./gradlew chromeHeadlessTest  # local Chrome in headless mode
$ ./gradlew firefoxTest         # local Firefox with UI

$ ./gradlew chromeRemote        # remote Chrome running in K8s
$ ./gradlew firefoxRemote        # remote Firefox running in K8s

Of course, we can also run the Geb test from within the cluster as a Cronjob or as an adhoc pod.

$ docker build -t lreimer/continuous-atdd:latest .
$ docker push

# either run continuously using cronjob
$ kubectl apply -f src/test/kubernetes/chrome-remote-cronjob.yaml -n selenium-hub
$ kubectl apply -f src/test/kubernetes/firefox-remote-cronjob.yaml -n selenium-hub

# or run adhoc pods
$ kubectl run chrome-remote-test --image lreimer/continuous-atdd:latest --restart=Never --attach --env="SELENIUM_HUB_HOST=selenium-hub" --env="SELENIUM_HUB_PORT=4444" --command -- ./gradlew chromeRemote
$ kubectl delete pod/chrome-remote-test

$ kubectl run firefox-remote-test --image lreimer/continuous-atdd:latest --restart=Never --attach --env="SELENIUM_HUB_HOST=selenium-hub" --env="SELENIUM_HUB_PORT=4444" --command -- ./gradlew firefoxRemote
$ kubectl delete pod/firefox-remote-test
