Assert that a test failure is a success

In a nunit test, can we an assert that if the test fails at a certain circumstance then it is a pass (i.e. it is expected to try and fail).

But it should pass under all other circumstances.

Thing is that the test could fall apart before it can reach it's assertions sections.

I mean something in the lines of 

[TestSetup]
void init()
{
    if (condition==true)
    {
    Assert.That(this test fails); /*any feature to do this?*/
    }
}
Solution

  • If the test can fail and it's classed as a pass under some circumstances, it sounds a bad test. Split it out into individual tests with clear method names detailing what it's achieving.

    So instead of having one test and having a conditional inside it, split it out into each scenario. That way you can have the one scenario, where it is supposed to fail under something like

    // do stuff
bool success = DoStuff();
Assert.IsFalse(success);
