Architecting Angular Applications with Redux, RxJS, and NgRx

Set up

Let's set up our environment correctly so we can write marble tests. We need the following:

• The NPM library jasmine-marbles
• A scaffolded Angular application

With that we scaffold our Angular project, like so:

ng new MarbleTesting

After the project has been scaffolded, it's time to add our NPM library, like so:

cd MarbleTestingnpm install jasmine-marbles --save

Now we have finished the setup, so the time has come to write tests.
