Build and test pipeline

On This Lesson 4 topics

This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.

In this lesson

build, test, and cache in a workflow.

Set up Java with actions/setup-java (distribution and version) and enable the Maven or Gradle cache.
Run ./mvnw verify so unit and integration tests run; GitHub's Ubuntu runners include Docker, so Testcontainers works.
Fail the build if tests fail; also check that tests actually ran (report in the logs or upload test reports).
Upload test reports as artifacts for debugging.
Keep the pipeline fast; cache dependencies, not build output you cannot trust.
