Maven does not find JUnit tests to run

I have a maven program, it compiles fine. When I run mvn test it does not run any tests (under TESTs header says There are no tests to run.).

I've recreated this problem with a super simple setup which I will include below as well as the output when run with -X.

The unit tests run fine from eclipse (both with its default junit package and when I instead include the junit.jar downloaded by maven). Also mvn test-compile correctly creates the class under test-classes. I am running this on OSX 10.6.7 with Maven 3.0.2 and java 1.6.0_24.

Here is the directory structure:

I also had a similar issue, after exploring found that testng dependency is causing this issue. After removing the testng dependency from pom (as I don't need it anymore), it started to work fine for me.

<dependency>
  <groupId>org.testng</groupId>
  <artifactId>testng</artifactId>
  <version>6.8</version>
  <scope>test</scope>
</dependency>

In case someone has searched and I do not solve it, I had a library for different tests:

<dependency>
  <groupId>org.junit.jupiter</groupId>
  <artifactId>junit-jupiter-api</artifactId>
  <version>${org.junit.jupiter.version}</version>
  <scope>test</scope>
</dependency>

When I installed junit everything worked, I hope and help this:

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

In my case it was adding the junit-vintage-engine which makes it compatible with older version of JUnit tests and can run them. As I'm using JUnit 5.

    <dependency>
      <groupId>org.junit.vintage</groupId>
      <artifactId>junit-vintage-engine</artifactId>
      <scope>test</scope>
    </dependency>

Here's the exact code I had to add to my pom.xml:

If you created a Spring Boot application using Spring Initializr, tests are running all right from Intellij Idea. But, if try to run tests from a command-line:

mvn clean test

You might have been surprised, that no tests were run at all. I tried to add surefire plugin with no luck. The answer was simple: pom.xml contained the following dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.junit.vintage</groupId>
            <artifactId>junit-vintage-engine</artifactId>
        </exclusion>
    </exclusions>
</dependency>

The exclusion, junit-vintage-engine, is dedicated for keeping backward compatibility with JUnit 4.x. So, new versions of Spring Boot Initializr do not support it by default. After I removed the exclusion, Maven started to see project's tests.

In my case this was not working because I did not include the surefire plugin to my pom.xml file. As described by the question, IntelliJ ran all of the tests without issue, and I could also run or debug individual tests by clicking in the margin, but Maven reported finding no tests to run.

After adding this to my pom.xml, Maven started running the unit tests and failing the CI build if any unit tests did not pass.

  <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.2.3</version>
        </plugin>
    </plugins>
  </build>

Please make sure to use junit-jupiter and NOT junit-jupiter-api (which I used accidentally)

  <dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>5.9.0</version>
    <scope>test</scope>
  </dependency>

Using Surefire plugin you might want to include all the files for testing:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M7</version>
    <configuration>
        <includes>
            <include>*</include>
        </includes>
    </configuration>
</plugin>

this way you can get all your files tested, not only the ones that include the pattern that Surefire requires.

I tried most of the answers in this thread but I got it working only when I did the following to my pom.xml.

It had the org.junit.jupiter as a seperate dependency

<dependencies>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>5.2.0</version>
    </dependency>
</dependencies>

But then I moved the same inside the maven-surefire-plugin plugin and the mvn clean install/test started detecting my test files which was under src/test/java

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <dependencies>
    <!-- moved here -->
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.2.0</version>
        </dependency>
    </dependencies>
</plugin>

Faced this issue while working on a spring boot project setup with Junit4. Jacoco maven plugin always returned 0.00 test coverage and maven surefire plugin ran 0 tests.

Removed junit-vintage-engine and surefire-junit47 dependency and added the following dependencies to run Junit 5 unit tests.

 <dependency>
   <groupId>org.junit.jupiter</groupId>
   <artifactId>junit-jupiter-engine</artifactId>
   <version>5.6.2</version>
   <scope>test</scope>
 </dependency>

Adding version lower than 5.6.2 led to ScriptEvaluationException.

Also using @ExtendWith(SpringExtension.class) instead of@RunWith(SpringRunner.class)

Probably not a common mistake but in addition to @João Matos's answer. Besides the requirement of your methods being public:

You're methods also should be void and of course have the @Test annotation.

This won't work:

@Test
public Integer fooBarTest() {
   // omitted
}

It must return a void:

@Test
public void fooBarTest() {
   // omitted
}

UPDATE:

Like @scottyseus said in the comments, starting from Maven Surefire 2.22.0 the following is sufficient:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.1</version>
</plugin>

When using JUnit 5, i ran into the same problem. Maven Surefire needs a plugin to run JUnit 5 tests. Add this to our pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <dependencies>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>1.2.0-M1</version>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.2.0-M1</version>
        </dependency>
    </dependencies>
</plugin>

Source: https://junit.org/junit5/docs/current/user-guide/#running-tests-build-maven

UPDATE 2021

The junit-platform-surefire-provider, which was originally developed by the JUnit team, was deprecated in JUnit Platform 1.3 and discontinued in 1.4. Please use Maven Surefire’s native support instead.

I also found that the unit test code should put under the src/test/java folder, it can not be recognized as test class if you put it under the main folder. eg.

Wrong

/my_program/src/main/java/NotTest.java

Right

/my_program/src/test/java/MyTest.java

Another easily overlooked problem I recently experienced - Ensure your Test class' file has the .java extension. If there's no tests to compile, there are no tests to run

In my case, my parent pom had a parent:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>some version</version>
    <relativePath/>
</parent>

After changing to importing a spring pom:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>some version</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

My unit tests started to run

The Maven Surefire plugin supports several test frameworks. It tries to autodetect which framework you are using, then looks for tests written using that framework. If that autodetection is confused, and chooses the wrong framework, the second stage will not find your tests.

The autodetection works by scanning the classpath for the presence of significant "driver" classes for the test frameworks it supports. Therefore the autodetection can go wrong if your POM, or a depended on module, has an incorrect dependency on one of those "driver" classes.

At present (2020), a particular problem is the difference between JUnit 4 and JUnit 5. The Surefire plugin treats them as different frameworks. But because of the similarity in the package names, a project can have a dependency on the wrong framework but seem OK to a casual inspection.

In particular, beware that junit-platform-console is for JUnit 5, but junit-platform-runner is for JUnit 4. If your project has a dependency on the latter, Surefire will not run your JUnit 5 tests.

If your test class name does not follow the standard naming convention (as highlighted by @axtavt above), you need to add the pattern/class name in the pom.xml in order to Maven pick the test -

...
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <includes>
                    <include>**/*_UT.java</include>
                </includes>
            </configuration>
        </plugin>
    </plugins>
</build> 
...

By default Maven uses the following naming conventions when looking for tests to run:

If your test class doesn't follow these conventions you should rename it or configure Maven Surefire Plugin to use another pattern for test classes.

I struggle with this problem. In my case I wasn't importing the right @Test annotation.

1) Check if the @Test is from org.junit.jupiter.api.Test (if you are using Junit 5).

2) With Junit5 instead of @RunWith(SpringRunner.class), use @ExtendWith(SpringExtension.class)

import org.junit.jupiter.api.Test;

@ExtendWith(SpringExtension.class)
@SpringBootTest
@AutoConfigureMockMvc
@TestPropertySource(locations = "classpath:application.properties")    
public class CotacaoTest {
    @Test
    public void testXXX() {

    }
}

In my case we are migration multimodule application to Spring Boot. Unfortunately maven didnt execute all tests anymore in the modules. The naming of the Test Classes didnt change, we are following the naming conventions.

At the end it helped, when I added the dependency surefire-junit47 to the plugin maven-surefire-plugin. But I could not explain, why, it was trial and error:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<dependencies>
  <dependency>
    <groupId>org.apache.maven.surefire</groupId>
    <artifactId>surefire-junit47</artifactId>
    <version>${maven-surefire-plugin.version}</version>
  </dependency>
</dependencies>

Following worked just fine for me in Junit 5

https://junit.org/junit5/docs/current/user-guide/#running-tests-build-maven

<build>
    <plugins>
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.0</version>
        </plugin>
        <plugin>
            <artifactId>maven-failsafe-plugin</artifactId>
            <version>2.22.0</version>
        </plugin>
    </plugins>
</build>
<!-- ... -->
<dependencies>
    <!-- ... -->
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>

Such problem might occur when you use surfire plugin 3.x.x+ with JUnit5 and by mistake annotate the test class with @Test annotation from JUnit4.

Use: org.junit.jupiter.api.Test (JUnit5) instead of org.junit.Test (Junit4)

NOTE: this might be hard to notice as the IDE might run this wihout problems just as JUnit4 test.

Many of these answers were quite useful to me in the past, but I would like to add an additional scenario that has cost me some time, as it may help others in the future:

Make sure that the test classes and methods are public.

My problem was that I was using an automatic test class/methods generation feature of my IDE (IntelliJ) and for some reason it created them as package-private. I find this to be easier to miss than one would expect.

I faced the same issue , it resolved by below change in pom.xml :

<build>
    <testSourceDirectory>test</testSourceDirectory>

...

changed to: 

<build>
    <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>

If you have written your tests in JUnit 4 and added JUnit 5 dependencies to the surefire plugin, your tests will not run.

In that case, just comment JUnit 5 dependencies from surefire plugin:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <!--<dependencies>-->
                <!--<dependency>-->
                    <!--<groupId>org.junit.platform</groupId>-->
                    <!--<artifactId>junit-platform-surefire-provider</artifactId>-->
                    <!--<version>1.0.0</version>-->
                <!--</dependency>-->
                <!--<dependency>-->
                    <!--<groupId>org.junit.jupiter</groupId>-->
                    <!--<artifactId>junit-jupiter-engine</artifactId>-->
                    <!--<version>${junit.version}</version>-->
                <!--</dependency>-->
            <!--</dependencies>-->
        </plugin>

One more tip (in addition to the previous answers):

In Eclipse, go to your project's Properties > click Run/Debug Settings:

"This page allows you to manage launch configurations with the currently selected resource"

In there you can add (New...) or remove (Delete) any JU (JUnit) tests you have in your project (under the src/test/java folder, or course).

/my_program/src/test/java/ClassUnderTestTests.java

should be 

/my_program/src/test/java/ClassUnderTestTest.java

The Maven finds those ends Test or starts with Test to run automatically.

However, you can using 

mvn surefire:test -Dtest=ClassUnderTestTests.java

to run your tests.

Another reason for not running the test cases happened to me - I had a property named "test" for completely different purposes, but it interfered with the surefire plugin. Thus, please check your POMs for:

<properties>
  <test>.... </test>
  ...
</properties>

and remove it.

junitArtifactName might also be the case if the JUnit in use isn't the standard (junit:junit) but for instance...

<dependency>
    <groupId>org.eclipse.orbit</groupId>
    <artifactId>org.junit</artifactId>
    <version>4.11.0</version>
    <type>bundle</type>
    <scope>test</scope>
</dependency>

Maven will not run your tests if the project has <packaging>pom</packaging>

You need to set the packaging to jar (or some other java artefact type) for the tests to run: <packaging>jar</packaging>
