¿Cómo me burlo de una interfaz en NUnit?

How do I mock an interface in NUnit?

The three key steps to using mock objects for testing are:

1. Use an interface to describe the object.
2. Implement the interface for production code.
3. Implement the interface in a mock object for testing.

Add a new method name “When_PremiumCustomer_Expect_10PercentDiscount” and add [TestCase] attribute. All test cases method are public and void return because in the test cases we should not return any value. We should write NUnit test method name in special naming convention.

1. Add the NUnit 3 library in NuGet.
2. Create the class you want to test.
3. Create a separate testing class. This should have [TestFixture] above it.
4. Create a function in the testing class. This should have [Test] above it.
5. Then go into TEST/WINDOW/TEST EXPLORER (across the top).
6. Click run to the left-hand side.

Setup methods (both types) are called on base classes first, then on derived classes. If any setup method throws an exception, no further setups are called. Teardown methods (again, both types) are called on derived classes first, then on the base class.

mock is a library for testing in Python. It allows you to replace parts of your system under test with mock objects and make assertions about how they have been used. unittest. mock provides a core Mock class removing the need to create a host of stubs throughout your test suite.
