JUnit4 run all tests in a specific package using a testsuite

Question

Is this possible in JUnit4?

In JUnit3, I would do the following:

public class MyTestSuite {

  public static Test suite() throws Exception {
     doBeforeActions();

     try {
        TestSuite testSuite = new TestSuite();
        for(Class clazz : getAllClassesInPackage("com.mypackage")){
            testSuite.addTestSuite(clazz);
        }
        return testSuite;
     } finally {
        doAfterActions
     }
  }

...

}

Answer 1

The takari-cpsuite (originally developed by Johannes Link) offers a classpath-suite which should fit your needs. It allows filtering of classes in the Classpath by regular expressions like:

import org.junit.extensions.cpsuite.ClasspathSuite.*;
...
@ClassnameFilters({"mytests.*", ".*Test"})
public class MySuite...

You can use JUnitToolBox:

@RunWith(WildcardPatternSuite.class)
@SuiteClasses("**/*Test.class")
public class MySuite {
}

Maven config:

<dependency>
<groupId>com.googlecode.junit-toolbox</groupId>
<artifactId>junit-toolbox</artifactId>
<version>1.5</version>
</dependency>
