What are mocking frameworks?
To construct fake objects, mocking frameworks (Moq, NSubstitute, Rhino Mocks, FakeItEasy, and NMock3) are utilised. We can stub, or totally replace, a member’s body and function. It helps developers execute unit testing in a succinct, efficient, and reliable manner by isolating each dependency.
Manually creating mock objects is complex and time-consuming. So, if you want to boost your productivity, you can use a Mocking Framework to generate fake objects automatically. A developer can use any of the unit test frameworks such as NUnit, MbUnit, MSTest, xUnit, and others to create his or her unit test.
