How do I handle exceptions in NSubstitute?

In NSubstitute, you can handle exceptions by using the When method to specify the behavior of a substitute when a certain method is called.

Can you give me an example of that?

Sure! You can do something like this: substitute.When(x => x.Method()).Do(x => throw new Exception("Error occurred")); This will throw an exception when Method is called.

What if I want to return a default value instead of throwing an exception?

You can use the Returns method to specify a default value. For example: substitute.When(x => x.Method()).Returns(defaultValue); This will return defaultValue instead of throwing an exception.
