Description:

This lesson describes what a Matcher is, and how you can use the provided anyString() matcher to return stubs for methods which accept String parameters. When you stub a method which takes a String parameter, you can configure your stubs to only match on specific Strings, or you can configure your stub to match on any String; this lesson will show you how to achieve both of these options. Additionally, if you pass null instead of a String to the stubbed method and want your stubbed answer to be returned, you will need to use a different matcher, as discussed in the lesson.
