I didn't know much about writing test code, but I was able to easily understand Cypress! I listened to the lecture while following the code, and I was able to complete the course in just one day. However, since it was a lecture from a while ago, there were some differences in versions from Cypress, but I was able to easily solve this problem with GPT. I highly recommend this course to anyone who wants to quickly and easily understand what test code is, not just Cypress!
