Inclusion classes

http://maven.apache.org/surefire/maven-surefire-plugin/examples/inclusion-exclusion.html

By default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns:

"**/Test*.java" - includes all of its subdirectories and all java filenames that start with "Test".
"**/*Test.java" - includes all of its subdirectories and all java filenames that end with "Test".
"**/*TestCase.java" - includes all of its subdirectories and all java filenames that end with "TestCase".

Import methods

   1  import static org.junit.Assert.*;
   2   //  ...
   3   assertEquals(...);

Maven dependency

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

On a Maven project the tests may be located inside /src/test/java/ so they are integrated in the main artifact generated by Maven.
