Failed to execute unit tests using maven : No tests executed

Question

While running unit tests using maven I am getting this exception. None of my tests is getting executed. My test classes are of format **/*Tests.java

Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.14.1:test (default-test) on project myproject: No tests were executed!  (Set -DfailIfNoTests=false to ignore this error.) -> [Help 1]

I am running following command to run this :

mvn -e test -DskipTests=false

The surefire plugin used is :

           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.14.1</version>
                <configuration>
                    <includes>
                        <include>**/*Tests.java</include>
                    </includes>
                    <skipTests>${skipTests}</skipTests>
                </configuration>
            </plugin>

Does any one have idea why my tests are not getting executed? I am using junit 4.8.2 and surefire 2.14.1

In my case I imported org.junit.Test instead of org.junit.jupiter.api.Test class. Check your import:

import org.junit.jupiter.api.Test
