Advanced React Testing: Redux Saga and React Router

Advanced React Testing: Redux Saga and React Router

Are you a developer who's learned the basics of React testing and wants to move to the next level? This course dives deep into React testing for sophisticated apps.

Test Redux Saga, React Router or Both

The Redux Saga and React Router sections of the course are completely separate. You can choose which technology to start with, and skip the sections for technologies that aren't relevant to your app.

Test an Existing App

The app for the course is already built, so you'll be testing an existing app that utilizes Redux Saga and React Router (with Auth-Protected Routes). For an added bit of fun, the app is for a music venue that sells tickets to shows for fake bands, complete with fake band names, plus randomized band descriptions and photos.

redux-saga-test-plan

Test Redux Sagas with the redux-saga-test-plan library, a powerful module that allows flexible integration testing and precise unit testing. The course covers the `provide()` method for static and dynamic effect mocking. 

React Router

The course creates a custom `render` method for Testing Library to write tests that can assert either on page behavior or the React Router `history` object. Tested routes include URL and query params, and the flow for auth-protected routes (including removing the sign-in page from the history). Mock Service Worker provides mocked data for network calls to the server.

Jest's test.each()

In both the Redux Saga sections and the React Router sections, the course teaches Jest's test.each() method for parametrizing tests (that is running the same test multiple times with different data).

TypeScript

Following modern JavaScript best practices, all course code is typed via TypeScript.

Proven Instructor

The instructor for this course has been writing courses for Udemy since 2018, and has a great track record of courses that are clear and easy to follow. She loves interacting with students via Q&A and has a calm, supportive teaching style.
