FIRST unit tests code Reading time min I devoted several articles to the topic of unit testing on my blog Basics of automated software testing About Test Driven Development If you haven't read them yet I encourage you to do so. This time I will discuss the principles that should be followed when writing unit tests. These principles are gathered under the acronym FIRST. We can decode it as F ast S elf validating T imely T horough FIRST unit tests the Fast principle Fast Unit tests should be fast.
Unit tests are used to test the smallest elements of a system usually methods. There should be and usually is the most such tests in the system. The number of such tests can grow exponentially thousands of unit tests in the system are not unheard of . Moreover unit tests are run most often so their execution time should be as short as possible. To optimize the execution time of unit tests we can do a few things. First of all you should avoid the so called "waiting" . If our code uses time based methods i.e. timeouts intervals sleeps etc. the system time should be mocked. In JavaScript this can be achieved using a library or using the method described in this article.
