Build a CLI App with Oclif and Node.js Using Test-Driven Development: Part 2

In summary, we laid out plans for using TDD to build a CLI application using the oclif framework. We spent some time getting to know the @oclif/test package and some of the helpers provided by that library. Specifically, we talked about:

– Using the command method for calling our command and passing it arguments.

– Methods provided by @oclif/fancy-test for stubbing parts of our application, catching errors, mocking stdout and stderr, and asserting on those results.

– Using TDD to build out a large portion of a CLI using a red-green cycle by writing tests first and then writing the minimal amount of code to get our tests to pass.
