Join David Gassner for an in-depth discussion in this video Exploring test-driven development with the assert keyword, part of Java Advanced Training.
In this chapter of the video series I am going to describe some strategies for advanced exception…handling and for testing your code, and I'm going to start in this video with the Assert command.…Assert is a way of testing a condition your code.…For example, let's see you going to pass a value into a method, and you wanted to make…sure that that value matched a certain condition before you passed in.…You could assert that condition, you create the Assert command and then place the condition…after it, and if the Assert is false it'll throw an exception.…
You can't depend on asserts for real functionality in your application, they are only for testing…when you're coding, and that's because asserts can be disabled.…In fact, they only work when you add a certain command line value after the call to the virtual machine.…I'll show you how to use Asserts in this project UsingAsserts, and this code is a version of…a Calculator application that I created in Java Essential Training.…This version of the Calculator looks a little bit different than the older version.…
