SpringBoot and GitLab CI to run tests

sebasira :

I would like to just use GitLab CI to run test only not to deploy my app. I manage to assembly this .yml file:

image: java:8

stages:
  - build
  - test

build:
  stage: build
  script: ./gradlew build
  artifacts:
    paths:
      - build/libs/myApp-4.0.0-SNAPSHOT.jar

unitTests:
  stage: test
  script:
    - ./gradlew test

And in the GitLab Pipeline I get the following error:

ar.com.sebasira.myApp.myAppApplicationTests > contextLoads FAILED java.lang.IllegalStateException Caused by: org.springframework.beans.factory.BeanCreationException Caused by: org.springframework.beans.BeanInstantiationException Caused by: org.springframework.beans.factory.BeanCreationException Caused by: org.springframework.beans.BeanInstantiationException Caused by: org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException

I'm guessing this could be related to database, right? I need to provide that database with credentials in my Server where the runner is?

If so, how should I do it? I'currently using application.properties file to define the connection to the DB.

And one more question... in the .gitlab-ci.yml file I need to put the path to the .jar but that filename will change everytime I update the version of my app. Do I need to manually change it?

As you are starting the whole Spring context with this test (I think it's the generated standard test from Spring Boot) with the annotations @RunWith(SpringRunner.class) and @SpringBootTest you have to provide a datasource. You can do one of the following:

• Specify the database credentials in your application.properties in src/test/resources (you could provide a test database on your database server as I wouldn't connect to your production database on every test)
• Use an embedded H2 for this test
• Use https://www.testcontainers.org/ to provide a real and fresh database for your Spring application test

Regarding your GitlabCI question: Just use * to match any .jar no matter which version: - build/libs/myApp-*.jar
