Re: [mockito] argThat with verify causes NullPointerException

[Eric Lefevre-Ardant]

hm... I had never tried that before, but it does seem to work for me. Here is something that worked fine in my own tests:

    verify(configurationClient).setHost(org.mockito.Matchers.argThat(org.hamcrest.CoreMatchers.not(org.hamcrest.CoreMatchers.equalTo("host"))));

    verify(configurationClient, org.mockito.Mockito.never()).setHost(org.mockito.Matchers.argThat(org.hamcrest.CoreMatchers.not(org.hamcrest.CoreMatchers.equalTo("host"))));

Maybe you are not importing the right classes/static imports?

I'm getting a NullPointerException when I try to use argThat with verify:

    import static org.hamcrest.CoreMatchers.equalTo;

    // Causes NPE

    verify(collaborator, never()).doSomething(eq("String"), argThat(equalTo(1)));

But other argument matchers seem to work:

    // This works as expected

    verify(collaborator, never()).doSomething(eq("String"), eq(1));

Am I using argThat incorrectly?  I need to use argThat because (unlike the example above), I want to check argThat(not(equalTo(1))).  I'm getting the same NPE whether or not I use never().  I'm using mockito-1.9.5-rc1, hamcrest-1.2.1 and junit-4.10.

Hi,

Where the NPE is coming from (stack trace) ?
