Progress Telerik JustMock
JustMock utilizes a AAA pattern that helps you keep your unit tests well structured, clean and readable. It comes with one intuitive, fluent and easy-to-use API with better discoverability.
This simple pattern, Arrange, Act, Assert (AAA) makes it easy to quickly and intuitively mock objects in unit tests.
With AAA, there is always a single starting point and options are contextually valid. The AAA pattern helps you keep your unit tests well structured, clean and readable. This pattern stays the same, regardless of what you are mocking.
