Jest and Enzyme Testing

The Jest and Enzyme Testing training course is designed to provide a comprehensive training on testing with Jest and Enzyme. This course begins with an introduction to both Jest and Enzyme including a review of class architecture, test applications and using Jest and Enzyme to validate accessibility requirements. Students will then explore how to do tests, code coverage, and snapshots. Finally, the course delves into test mocking, shallow rendering of components, and full rendering. This course uses a mixture of lecture and hands-on labs to reinforce learning.

Course Summary

Provide a solid foundation in the workings of the Jest testing framework along with the testing utility Enzyme.
Web Developers and Q/As looking to adopt Jest and Enzyme.
Skill Level: 
Learning Style: 

Workshops are instructor-led lab-intensives focused on the practical application of technologies through the facilitation of a project-related lab. Workshops are just the opposite of Seminars. They deliver the highest level of knowledge transfer of any format. Think wide (breadth) and deep (depth).
