In this chapter, we have tested various parts of our web shop. With Jasmine and Karma, it is possible to create unit tests that run whenever you change something. Depending on the quality and coverage of your tests, errors can be found as soon as they are introduced. Going a step further, we can test our application as though it was tested by an actual human using Selenium and Protractor. In the next chapter, we are going to automate our build, including testing, linting, and minifying, using Gulp, a JavaScript task runner.
