Selenium Grid demo on ROSA

Step 1 - Install Selenium Grid

helm repo add docker-selenium https://www.selenium.dev/docker-selenium

# Update charts from docker-selenium repo
helm repo update

# List all versions present in the docker-selenium repo
helm search repo docker-selenium --versions

# Install basic grid latest version
helm install selenium-grid docker-selenium/selenium-grid

Step 2 - Access Selenium Grid

oc port-forward service/selenium-hub 4444:4444

Access the UI on http://localhost:4444

Verify that Selenium Grid is ready by checking the status on http://localhost:4444/wd/hub/status

Step 3 - VNC access

oc port-forward -p service/selenium-chrome-node 6900:6900

With your preferred VNC client, open 127.0.0.1:5900 with the default password secret.

Step 4 - Run test locally

python3 -m venv .venv\n
. .venv/bin/activate\n
pip install selenium
python test_suite.py

Set the Selenium Hub endpoint:

export SELENIUM_HUB_ENDPOINT='http://localhost:4444/wd/hub'

When the test runs, you should see a browser window opening Chrome and going to example.com.

In your terminal, you should see the test result:

----------------------------------------------------------------------
Ran 1 test in 2.435s

OK

Step 5 - Run test in OpenShift (CI/CD)

In the Operator Hub, install the operator named "Red Hat OpenShift Pipelines" provided by Red Hat.

Verify that all Pipelines containers installed by the operator are running in the openshift-pipelines namespace.

Build the image. For simplicity, we will build and push an image in Docker Hub.

docker buildx build --platform linux/amd64 . -t willgarcia/selenium-test
docker push willgarcia/selenium-test

Create and run the CI/CI pipeline (Tekton):

oc apply -f selenium-test-task.yaml
oc apply -f selenium-test-taskrun.yaml
oc apply -f selenium-test-pipeline.yaml
oc apply -f selenium-test-pipelinerun.yaml
