Can you unit test abstract classes?
We can use abstract classes in many more scenarios depending upon the design followed. Also, writing unit tests for abstract class methods is as important as for normal classes and methods. We can test each of them using different techniques or different test support libraries available.
Can we write unit test for protected methods?
Protected methods form a different contract between your class and its future children, so you should really be testing it to a similar extent as your public interface to ensure that the contract is well defined and exercised. No! Only test interfaces.
Can you write unit tests with protected methods?
If you write tests after writing the production code it is still possible to do so without changing too much of the code even with protected methods. If the code has been written using encapsulation there must be a reason for that and therefore the tests should not force you to break everything down. What about private methods?
Do you unit test abstract classes or private methods?
Unit testing abstract classes leads to the same consequences as unit testing private methods. In fact, these two practices are essentially the same anti-pattern. Both couple your tests to implementation details and therefore increase the noise you have to deal with after each refactoring.
How to test protected methods in C #?
Add to AssemblyInfo.cs in the assembly containing the internal methods You can expose the protected methods in a new class that inherits the class you want to test. You can use PrivateObject class to access all the private/ protected methods/ fields.
What’s the difference between unit test and concrete class?
Unit test all classes — When you test each class separately ( Student, Professor, and Person) Unit test only concrete classes — When you test only the non-abstract classes ( Student and Professor) Let’s discuss them separately. 2. Test class per each production class
