Compare three types of Node.js application testing: unit testing, which tests the smallest testable application; integration testing, which combines components together; and functional testing, which validates results against specifications.
- [Instructor] There are a number of…different ways to test software.…The most common techniques are unit testing,…integration testing, and functional testing.…Let's explore each in order as they build upon each other.…Before I define unit testing, it'd be good…to know what a unit is.…A unit is the smallest testable part of an application.…The size depends on how the application was built.…In a procedural application, it can be…an entire module or an individual function.…For object oriented applications, it can be…as big as an interface like a class…or more often an individual method.…
With that in mind, let's take a look at unit testing…which tests a completely isolated unit of code…via its application program interface.…Unit tests are performed in memory meaning…no permanent changes take place.…This makes them safe to run over and over again.…Additionally, unit tests execute very quickly…which makes them invaluable to development.…Unit tests are made up of assertions…which validate the correctness of a unit.…
