Question

I want to make a unit test suite of the same object with same variable but different values. However if the object get the same name (created by this.setName("testlaunch"); (we must have the name of a method tested by JUnit), it runs only one test.

If i don’t write this.setName("testlaunch"); it complains saying junit.framework.AssertionFailedError: TestCase.fName cannot be null.
I don’t know what to do…

public class LanceurRegleGestion extends TestSuite
{
    public static Test suite()
    {
        Class maClasse = null;
        TestSuite suite = new TestSuite();

        String filtre = ".*.xml";
        // on compile le pattern pour l'expression réguliere
        Pattern p = Pattern.compile(filtre);
        String path = "D:/Documents/workspace/Solipsisme/src/ReglesGestion/XML/";
        // on liste les fichiers du repertoire
        String [] u = new File(path).list();
        // on parcours la liste de fichier
        System.out.println("Initialisation");


        for (int i=0; i

Answer 1

Being new to junit, I stumbled upon this question hoping to solve a problem I had getting the same message. Through further research, I found that it is necessary to pass the name of the test function you want to invoke through addTest to the constructor of the test case class. A simple (and useless, other than illustration) example follows:

JunitTestCases.java

import junit.framework.TestCase;
public class JunitTestCases extends TestCase {
    public JunitTestCases(String fnName) {
        super(fnName);
    }
    public void testA() {
        assertTrue("assertTrue failed", true);
    }
}

JunitTestSuite.java:

import junit.framework.*;

public class JunitTestSuite {
    public static Test suite() {
        TestSuite suite = new TestSuite();
        suite.addTest(new JunitTestCases("testA"));
    return suite;
    }

    public static void main(String[] args) {
        junit.textui.TestRunner.run(suite());
    }
}

When I compiled with:

javac -cp .:path/to/junit-X.X.X.jar JunitTestSuite.java

and ran with

java -cp .:path/to/junit-X.X.X.jar JunitTestSuite

this worked with no errors, with junit giving me an OK message.
