QUESTION
I want to use jest and puppeteer to do e2e testing on a react app. I want the dev server to start up as part of the command to start the tests. In other words, I dont want to have to start the dev server separately and then run the e2e tests. Im just the jest-puppeteer library because I read that you can do that with this library. I have tried to get this to work but it fails with the error:
Logging in › Splash renders net::ERR_CONNECTION_REFUSED at http://localhost:3000
My e2e test file
...ANSWER
Answered 2022-Mar-25 at 19:14I found the solution. First I had to make sure that jest was version: "jest": "26.6.0" in package.json.
Then I had to add this to the top of the file jest.config.cjs
QUESTION
I'm trying to create some e2e tests via puppeteer and jest, and now I'm stuck with a problems regarding global variables. So I have 2 issues:

i use a codebase made with Vue3 Vite, but i cannot find a way to run a simple Jest test importing a component. This works fine in an app create with Vue-cli, but i cannot find a way to make Jest work in a Vue-Vite app with Vue3. Here is the error I encounter

QUESTION
Scenario
npm test used to work without issue. Over the course of a month or so (I neglected tests) something changed and now I receive ReferenceError: document is not defined when trying to run Jest-Puppeteer tests via npm test.
This error shows up even with document removed so it seems like a puppeteer issue but I'm not sure why this is showing up now. I've checked out code from over a month ago and the tests still work but so much has changed that it's difficult to chase down the actually issue.
Attempted Solutions
- upgrade node
- reinstall npm packages
- revert
jest-puppeteer.config.jsto previous version - add
@jest-environment jsdomto tests which fixes the document issue but then causesReferenceError: page is undefined

QUESTION
Scenario
I'm working on an app that has fast unit/functional jest tests along with slower end-to-end jest-puppeteer tests. I would like to split those up so that I can run the faster tests as part of a git pre-commit hook and leave the end-to-end tests to be run on CI after the code is eventually pushed to origin.
Question
How can I define specific tests to run at pre-commit? Specifically via regex similar to jest moduleNameMapper eg /__tests__/[a-z]+\.unit\.test\.js
- Best idea so far:
in package.json add test:pre which uses bash find . -regex with bash for do to run desired "pre commit" tests
