In Part One of this series on the oclif testing library, we used a test-driven development approach to building our time-tracker CLI. We talked about the oclif framework, which helps developers dispense with the setup and boilerplate so that they can get to writing the meat of their CLI applications. We also talked about @oclif/test and @oclif/fancy-test, which take care of the repetitive setup and teardown so that developers can focus on writing their Mocha tests.
Our time-tracker application is a multi-command CLI. We’ve already written tests and implemented our first command for adding a new project to our tracker. Next, we’re going to write tests and implement our “start timer” command.
