Running Webdriver test and TestNG @Test(invocationCount=?)

[Rahul]

Hiya,

When running TestNG tests if I set the invocationCount to, say, value
of '2', the first test run passes, but the second one fails. I can't
make anything of the error message for IE but Firefox spits out a
weird message. With an invocationCount = 1, all is fine.

Messages are included below.

Cheers,

Rahul

WebDriver is not thread safe - you could get that error from reusing
the same driver instance, so make sure you are creating a new instance
for each invocation.
