Wnt / ci-testbench-demo

Vaadin Flow template project that runs TestBench test in GitLab CI

Building the project

mvn install - will run unit tests, but no TestBench tests.

To run TestBench tests locally on development machine

Run mvn --activate-profiles=local-it verify.

How CI runs tests:

CI runs command line mvn --activate-profiles=gitlab-it $MAVEN_CLI_OPTS verify.

How it all works

pom.xml

When local-it or gitlab-it is activated, jetty-maven-plugin is configured to start jetty in Maven's pre-integration-test phase and stop it in post-integration-test.

maven-failsafe-plugin will run any @Test annotated methods from classes matching to patterns: **/IT*.java, **/*IT.java and **/*ITCase.java.

Test code

org.vaadin.jonni.testbench.MyIT extends TestBench's ParallelTest which looks up from Java system property com.vaadin.testbench.Parameters.hubHostname where it can find a remotely conrollable web browser.

.gitllab-ci.yml

Defines environment variables, Docker images and commands for Docker based build pipelines. See .gitllab-ci.yml and GitLab documentation for more info.

Appendix

When modifying the .gitlab-ci.yml it can be extremyly useful to debug the GitLab CI builds locally.
