Why Learn to Test?
Test Driven Development will help you write better organized code that's easier to maintain, which will save you time in the long run. Your tests provide value to your software development team, since others know they can rely on your code. Employers want developers with testing skills!
Learn the Reasons behind the Syntax
This course discusses tradeoffs when considering different approaches to testing, leaving you confident in the testing choices you make. Furthermore, you will deepen your understanding of React and Redux as we dig into how and why we test each aspect.
Practice your New Skills
You will also have opportunities to practice what you've learned. There are occasional "quizzes" while we're building the course projects, where you can apply what you learned, and then watch a video to see the solution. There are also two sets of challenges to extend the course projects, with solutions on GitHub. Who this course is for:
- Programmers interested in improving their React apps with testing
My teaching career started when I played school with my (not very willing) younger brother as a kid. I gradually expanded my horizons to teaching (marginally) more willing high school students, and more recently have taught software development at various boot camps to delightfully willing adults. I have been working in the software industry on and off since the mid-90s, which predates the birth of many coders in the San Francisco tech scene.
