Angular Testing Masterclass (Angular 15)

This Course in a Nutshell

This video course, complete with a running GitHub repository, is a full step-by-step guide to Angular Testing in general. We will take a small sample application that is already completed but has no tests yet.

We are then going to discuss the best approach to test each part of the application, and we are going to



write the tests step-by-step



, explaining



every decision along the way



.

We will start by writing



Unit Tests



for the multiple parts of the application, and then at a later stage, we will learn how to perform End to End (



E2E



) tests.

More than talking about



how



to test, this course will also cover



when and why and



all sorts of stretching best practices.

Course Overview

Starting from scratch, we will introduce



behavior-driven testing concepts



by quickly introducing the main ideas and utilities of the Jasmine Testing framework.

We are then going to introduce some testing best practices, and we are going to talk about



mocks and Jasmine spies



. We will then introduce some of the Angular Testing utilities, such as the Angular TestBed, which we will use to test a couple of simple Angular services.

We will then move on to test a more complex Angular service and talk about Angular HTTP requesTestingng, after which we will cover the testing of Angular components.

We will learn how to test



Angular components



with and without the DOM and what parts of the element to try, and we will also cover in detail asynchronous tests using the



fakeAsync and async



utilities.

We will cover how to test several typical Angular components, such as presentational and innovative or container components, and we will learn how to



mock Angular Observable-based services



.

After unit testing the multiple components of our application, we will create a test suite of



End to End tests using Cypress.

Once we have the tests written for our application, we will deploy them to



Travis CI



and ensure they are triggered with every commit.

At the end of the course, we will generate a test coverage report and discuss some of the metrics.
