使用 JUnit 进行单元测试

Question

I'm using NetBeans 7.4, and this is my first example with JUnit so i have this WARNING in the output console:

WARNING: multiple versions of ant detected in path for junit 
         jar:file:/C:/Program%20Files%20(x86)/NetBeans%207.4/extide/ant/lib/ant.jar!/org/apache/tools/ant/Project.class
     and jar:file:/C:/Program%20Files%20(x86)/glassfish-4.0/glassfish/modules/ant.jar!/org/apache/tools/ant/Project.class
Testsuite: utilitaire.TraitementFichierTest

Test utilitaire.TraitementFichierTest FAILED

Answer 1

What you have is a test failure, multiple junit versions(from Netbeans bundled & galssfish) is just a warning, doesn't cause a failure

    testCopyFile(utilitaire.TraitementFichierTest):   FAILED
expected:<false> but was:<true>
junit.framework.AssertionFailedError: expected:<false> but was:<true>
    at utilitaire.TraitementFichierTest.testCopyFile(TraitementFichierTest.java:52)

Check TraitementFichierTest.java line 52, you assert for a false, but gets a true, that is the cause for failure.
