This section will give a brief overview of Jasmine (http://jasmine.github.io) and Karma (https://karma-runner.github.io). We will set up a testing environment before writing concrete unit tests. For this purpose, the Webpack seed project introduced in the Setting up PrimeNG project with Webpack section of Chapter 1, Getting Started with Angular and PrimeNG, will be extended.
