assertNotEquals() method in Assert

[jottinger]

assertEquals() should have an analog that asserts inequality. There's precedent with assertSame() and assertNotSame(); you should be able to likewise assert that two values are NOT equal to each other.

I'd be more than happy to write some code for this, but I have a question: What's an acceptable style?

The first thing that comes to mind is copying the assertEquals() code, inverting it. But that's a ton of code. It's not difficult, it's just something to track.

The second thing - and the one that appeals most to me - is writing assertNotEquals in this mode:

assertNotEquals(object1, object2) {
try { assertEquals(object1, object2); } catch(AssertionFailure af) { fail(); }
}

What this does is obvious, but I don't know if using the exception mechanism that way is acceptable for the TestNG project.

I don't mind writing a patch, if the assertNotEquals() makes sense for everyone else, but I don't want to write a patch that's not acceptable.

I just added these methods to the Assert class, can you try them? You can download the beta at http://testng.org/beta

I just copy/pasted the ones that someone just submitted to

Interesting timing between you and Patrick.
