Overview/Description
Testing is a critical part of software development. This course will explore the built-in unit testing features of Ruby, as well as how to use Cucumber and behavior driven development (BDD) to help with testing Ruby code. Begin by learning how to describe unit testing. Next, create and run a test unit. From there you will identify assertion types, assert numerical values, strings with patterns, and objects. As you progress, you will learn how to install Cucumber, create a scenario project with it, and setup step definitions to run a test. Finally, as an exercise, you will use unit tests and behavior driven development to verify code functionality.
