setUp and tearDown

[Marilyn de Queiroz]

I thought that setUp was called before each testXxxx method and tearDown was called after each testXxxx method. However, when I try to initialize my object in setUp, I get a NullPointerException.

class Test extends TestCase
{
    TestObject testObject ;
    
    public void setUp()
    {
        testObject = new TestObject();
    }
    
    public void tearDown()
    {
        testObject = null ;
    }
    
    testXxxx()
    {
        testObject.someMethod(); // NullPointerException here
    }
}  

Am I doing something wrong? Am I misunderstanding the function of setUp and tearDown?

Is it same to assume that you extending the TestCase class? And that the method itself isn't throwing the null pointer exception?
From a logical perspective, you are doing everything right. And the code looks fine.

Yes.

Yes.

The following code does not throw the exception.

class Test extends TestCase
{
    TestObject testObject = new TestObject();
    
    testXxxx()
    {
        testObject.someMethod(); // [B]no[/B] NullPointerException
    }
}

This might be stupid. But could you tell us how you are running your test.

Are you totally sure you got the method signature right? It once happened to me that I accidentally wrote setup() instead of setUp()...

Thanks everyone. I must've mistyped something because I deleted those methods and retyped them and now everything works properly.
