Real-World TypeScript Unit Testing

You’re here because you know typescript and want to write better code with fewer bugs using unit tests.

I am here because I can help you accomplish your mission. I have B.s.c + M.s.c in mechanical engineering. I have been making software applications for over 20 years in the Hi-Tec industry and have much teaching experience. You can trust me and my teaching methods. I have learned many technologies in the past (check my LinkedIn profile), and I know exactly what is needed to learn and how.

In this course, I teach you everything you need about unit tests, and I use a real-world system, typescript, vitest, and jest.

The task of writing a unit test is not simple because there are many moving parts:

– Unit test of logic code

– Unit test of code with side effects like accessing the web

– Unit test of a module that uses another module

– Mocks

– Timers

– Unit test of UI

– Unit test of code that runs on the server

– Jsdom, testing library, react testing library

– Some tools like jest need a nontrivial setup to work with typescript and ES module

– New competitor to jest, e.g., vitest

– Coverage test

This ocean is very hard to swim without first learning it properly, and this is done in this course.

Learning in this course is not just video lessons; there are other important learning materials that most courses do not provide as a whole :

– Quiz after EVERY lesson

– Coding exercise at the end of EVERY coding section

– pdf file with all the lectures

– pdf file with a dictionary of all the material that I teach in this course
