[FIXED] No Tests Were Executed when using JUnit5 and Spring-boot-starter-parent

Issue

I have a very simple JUnit test class that I can not run unless I remove parent spring-boot-starter-parent from the pom, which wouldn't be a possibility for our production application. The error we get on is No Tests Were Executed and below is the mvp with the parent piece that whenever not commented out would block the tests. If I can get any guidance to know how to fix this please.

public class TestingTest {

}

Thank you.

Solution

The problem is related to that you trying to use a different version of junit jupiter. The version which is predefined by spring-boot-parent (2.2.4.RELEASE) is 5.5.2. The simplest solution is to remove the versions of junit-jupiter parts (version tag) and use the one which is inherited from spring-boot-parent. The best recommendation I can give is to start with a newer version of Spring Boot (2.3.3.RELEASE most recent one) which uses a more recent version.

If you can't go that way you have to use the junit-bom file instead like this:

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.junit</groupId>
        <artifactId>junit-bom</artifactId>
        <version>5.6.2</version>
        <scope>import</scope>
        <type>pom</type>
      </dependency>

Then it should work fine. Afterwards you have to use the dependencies without defining the version tag anymore in your pom.xml file.
