Assumptions

Assumptions are intended to express the state a test must be in to provide a meaningful result. They are functionally similar to assertions, however a unmet assumption will produce an Inconclusive test result, as opposed to a Failure.

Assumptions make use of the Assume static class.

Syntax

Assume.That(myString, Is.EqualTo("Hello"));

Assume.That() has the same set of overloads as Assert.That(). For further details there, see the Constraint Model documentation.

Note: Failing assumptions indicate that running tests is invalid, while Multiple Asserts allow testing to continue after a failure. For that reason, the two features are incompatible and assumptions may not be used used within a multiple assert block.
