    package JunitSuiteProject;


    import junit.framework.TestSuite;
    import junit.framework.Test;
    import org.junit.runners.Suite;
    import org.junit.runner.RunWith;
    import org.junit.runners.Suite.SuiteClasses;

    @RunWith(Suite.class)
    @SuiteClasses({JunitTest1.class})


    public class AllTests extends TestSuite{

        public static Test Suite(){
        TestSuite g = new TestSuite();
        g.addTest(new JunitTest1("testprintTest"));
        return g;
    }
        public static void main(String[]args){
            junit.textui.TestRunner.run(Suite());
        }
    }

Could anyone let me know what is the issue here when i have specified the location of Jars inside Junit why am i getting ClassNotFoundException Error when i trigger the Ant file.

The output says: 

[junit] Running AllTests
    [junit] Testsuite: AllTests
    [junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec
    [junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec
    [junit] Null Test:  Caused an ERROR
    [junit] AllTests
    [junit] java.lang.ClassNotFoundException: AllTests

The junit used is 3.8 version and it is executing fine as a junit test but giving error when started from build.xml file.

Answer 1

The junit.framework.Test package is the legacy namespace used by older projects that used JUnit v3 which was for versions of Java that did not support annotations.

The org.junit.Test package is the new namespace used by JUnit v4 which requires Java v1.5 or later for its annotations. Use JUnit 4 and the latest Java if possible because the new annotations are vastly superior.

The current distributions of JUnit 4 include a copy of the old namespace to allow easy migration; however you should avoid using JUnit3 form for new tests and convert old tests to JUnit 4 as you can.

In JUnit 4 both packages are included in the library jar for migrations purposes but you should use org.junit.Test for new code and those test do not need to extend TestCase.

You can see a basic example of Junit4 test case.
