In the second edition of The Art of Offline Testing, the author takes you step by step from the first simple offline test to creating a complete set of tests - understandable, easy to maintain and trustworthy. You will not even notice how you will move on to more complex issues - plugs and stands - and along the way learn how to work with insulating frames such as Moq, FakeItEasy or Typemock Isolator. You will learn about test patterns and test organization, how to refactor applications and test "unsuitable" code. The author did not forget about integration testing and testing of work with databases.
