  • Many developers confuse the ideas behind stubbing and mocking. Stubbing simply replaces a real-world implementation with a simpler implementation. In Listing 4, the stub replaced our full login system with a simple substitute. A stub's job is to simulate the real world. Mocks are not stubs. A mock object, instead, is like a gauge that measures the way your application uses an interface. I'll discuss stubs in more detail later and show you a few examples.
  • One of the most critical decisions you'll ever make is how much you test. If you don't test enough, you'll compromise your code quality and often even slow down your delivery time. You can test too much, too. Test too much, and you'll possibly miss deadlines that are important to the business. To make an informed decision about how much to test, you need to accurately measure how much you're already testing. One of the most critical measurements for testing is code coverage.
