Implement a small specification testing internal DSL for the language of your choice. In our example in Ruby, you can see a few specific details about specification testing that are necessary: define a subject, a concrete example, and the ability to make assertions about your expectations in the code. Demonstrate these constructs:

The ability to define your specification

The ability to define concrete, specific examples of specification testing

The ability to make expectations or assertions about the specification example

The internal DSL should work natively in your programming language of choice, and you should include an example implementation of a specification and supporting code. Using our previous example, your assignment deliverables should include the specification and the actual code required to make the specification pass or fail.
