* fix(jest-environment-puppeteer): Class & Exports This makes the typings actually compatible to create your own test environment and not just as part of the bigger jest-puppeteer package. How to do this is pretty much what the test covers. One of the reasons to do this is to write a handler where Puppeteer takes screenshots after each failed test, as discussed [here](https://github.com/smooth-code/jest-puppeteer/issues/131) * Change to `export =` syntax Co-Authored-By: Pranav Senthilnathan <pranav.senthilnathan@live.com> * Fix the last stuff requested
