Should I test every method?
The answer to the more general question is yes, you should unit test everything you can. Doing so creates a legacy for later so changes down the road can be done with peace of mind. It ensures that your code works as expected.
How do you mock a method call inside another method in the same class?
We can mock runInGround(String location) method inside the PersonTest class as shown below. Instead of using mock(class) here we need to use Mockito. spy() to mock the same class we are testing. Then we can mock the method we want as follows.
How to test methods that call other methods?
It is internal to the class and should not be accessed outside the class. Method 1 – This actually changes the class under test’s behaviour in the test. Method 2 – This actually does not test the production code, instead tests another implementation. In the problem stated, I see that the only logic of A is to see if the output of FunctionB is even.
Why is unit testing private methods considered as?
It is much better/safer to test edge cases on your private functions through your public interface. You risk severe test duplication (tests that look/feel very similar) by testing private methods. This has major consequences when requirements change, as many more tests than necessary will break.
When to not test a private method in C #?
If your method is private/protected – do not test it. It is internal to the class and should not be accessed outside the class. Method 1 – This actually changes the class under test’s behaviour in the test. Method 2 – This actually does not test the production code, instead tests another implementation.
Which is the best way to unit test a method?
In reality the functions are much more complex. So to test this we have 2 methods. Method 1: Use Functions and Actions to replace functionality of the methods. Example:
