Automated Testing

Although manual testing is and always will be an essential part of ensuring that your program works, automated testing is where things get interesting. You are a programmer now, and you automate everything from copying files to making your bed, so why not automate testing. We’re going to write code that tests our code. Confusing, right? I definitely thought so, but with a few examples, you’ll see that it’s really not so bad. The test code actually runs all or part of the application code and compares what happens to what was expected to happen. Testing how the entire application works together is called integration testing, and testing how a single part of the application works in isolation is called unit testing.
