Mvn build success but no tests are executed

Question

I have almost no idea why this could be happening but when I run

mvn clean install

or

#Builds with class instrumentation (code coverage)
mvn cobertura:cobertura

Everything was working just fine until I made a slight change which was to my pom.xml file, so it could contain dependencies classes I was using in my code rather than literally importing several classes into my project.

This is the terminal/console out I get when I run maven:

I really don't understand what could be causing this? Any help would be much appreciated. Thanks

That error you see for slf4j should be fine. I've seen that before, so I am certain thats not the culprit of what is happening here

Edit: I'm noticing that my test seem to be executing with TestNG but I'm using JUnit:

Why would mvn clean install try to build or run my tests with TestNG rather than Junit? Could it be the new dependencies I added?

Answer 1

Just to point. Make sure your test classes are in a test folder(package), and class name should be Test*, *Test, *TestCase.

Answer 2

Surefire has a mechanism to figure out whether to run JUnit or TestNG. Probably something in your dependencies/code is making surefire try to use TestNG.

You can disable the automatic detection and force a test provider (see the selecting providers in the documentation). Just for future reference, you need to configure surefire in the following way (taken from the previous link). This will force Surefire to use a Junit 4.7 compatible provider.

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.18.1</version>
    <dependencies>
      <dependency>
        <groupId>org.apache.maven.surefire</groupId>
        <artifactId>surefire-junit47</artifactId>
        <version>2.18.1</version>
      </dependency>
    </dependencies>
  </plugin>

I've seen this issue once before, about 6-7 years ago, and I cannot remember what I did to fix it to make Surefire detect the test provider properly, but I do remember debbuging the surefire plugin.
