wacat

wacat is a utility powered by Playwright to run chaotic tests on your web app, inspired by the manner a cat may chaotically walk across a keyboard, pressing every key.

Imagine, you leave your computer for a while and go to pick up a cup of coffee. Meanwhile, your cat walks over your keyboard and causes some chaos.

• goes to your web application root url
• visits every link in your application in random order

• detects error strings from the web pages
• you give the error strings in a parameter file
