XUnit - Assert.DoesNotThrow with Particular Exception Type Only

Question

Is it possible to use Assert.DoesNotThrow with a particular exception type?

For example how do I verify that a method call is not throwing NullReferenceExceptions specifically but it may throw NotSupportedException which I don't care about. ?

I think that Assert.DoesNotThrow comes from NUnit or XUnit, not from FakeItEasy. — rkrahl

'Assert.DoesNotThrow' it self is not there in the new release of XUnit github.com/xunit/xunit/issues/188. I'm still trying to understand the justification behind this decision. — Raathigesh

Brad: "Every single line of code is an implicit "does not throw", because if it throws, then the test fails." — robi-y

There's a pattern null checking in xUnit.

var ex = Record.Exception(...);
Assert.Null(ex);

It's bit late; however, hope it helps you :).
