Verifying sequence of private method calls in unit testing

Question

I have the following class:

class MyClass {

  public void doIt() {
     methodOne();
     methodTwo();
     methodThree();
  }

  private void methodOne() {
            


        

Answer 1

Hate to be the person but: simply don't test this. Test the output, side effects, results - not the implementation.

If you really want to ensure the correct order, extract these methods into separate class(es) and mock them.
