I want to test my Entities that are built using Entity Framework. My concern is that using Entity Framework means directly working with data source. So any ideas how to unit testing Entity Framework based components?
JUnit is an open-source unit testing framework for a test-driven development environment. It supports the core concept of “first testing then coding”. This framework is specifically designed for Java programming language. In this, data is first tested and then it is inserted in the piece of code.
Mocking Frameworks (Moq, NSubstitute, Rhino Mocks, FakeItEasy, and NMock3) are used to create fake objects. We can stub, i.e., completely replace the body of member and function. It is used to isolate each dependency and help developers in performing unit testing in a concise, quick, and reliable way.
The dbContextOptions carries the configuration information needed to configure the DbContext. The dbContextOptions can also be configured using the OnConfiguring method. This method gets the DbContextOptionsBuilder as its argument. It is then used to create the dbContextOptions.
For Enity Framework 4, this looks promising: Testability and Entity Framework 4.0
Apparently it's very hard. Eloquently put by Erik here - TDD and ADO.NET Entity Framework
