JavaScript is a dynamically typed language which comes with great power of expression, but it also comes with almost no help from the compiler. For this reason we feel very strongly that any code written in JavaScript needs to come with a strong set of tests. We have built many features into Angular which make testing your Angular applications easy. With Angular, there is no excuse for not testing.
