Running Maven Tests

Question

I am learning Java, part of the courseware is Maven.

I have created a simple Maven project. And in the test class I have added the following code:

package maventest2;

import org.junit.Test;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Tag;

public class firstclass {
    
@Tag("FirstTests")
@DisplayName("This is the first group test I working on")
@Test

public void someTest() {
    System.out.println("This in some test running");
}
}

When I run mvn test command I get the following:

Microsoft Windows [Version 10.0.18363.1256]

Why is the test not being run? When I use the option to Run As ->JUnit Test. It works fine and I get the passed result.

Please advice.

Directory structure of project

The test file is in src/test/java

Answer 1

Two reasons:

1. Your test class name doesn't match the regex you have in your surefire configuration. You have explicitly said that the class name needs to match *Test*

2. You are importing the @Test annotation from org.junit, not org.junit.jupiter.api.Test
