Below settings for my package.json
If I run from command line npm test
all jest test cases are executed properly. In case I use directly the command jest
from command line I receive this error:
Test suite failed to run
TypeError: Path must be a string. Received undefined at assertPath (path.js:7:11) at Object.relative (path.js:538:5)
This happens on any test files.
Any idea what could be wrong and how to fix it?
"scripts": {
"test": "standard && jest",
"format": "standard --fix",
"start": "webpack-dev-server --config webpack.config.dev.js",
"build": "webpack --config webpack.config.prod.js"
},
I solved this issue using:
I am not entirely sure what the problem here is, but I was facing the same issue and what worked for me was updating the Jest version. I was using 20 but I switched to 21 and now it magically works again.
Update version in package.json
and then run rm -rf node_modules && npm install
In my case i had to update jest to version 21.x (from 20.x).
Try running npm install jest@latest --save-dev
.
For me, it was the jest-cli package bumping to 21.x. So npm update jest-cli --save-dev
For me I had to downgrade. Version 21.x worked for me.
I solved this issue using:
remove node_modules
remove package-lock.json
remove dev dependence from package.json
of jest npm remove jest --save-dev.
npm cache clean
then run command npm install
then install npm install jest@latest --save-dev
this works for me
npm install react-dev-utils@10.1.0
Installing this version of react-dev-utils
helped, when sometimes the commands in the accepted answers didn't.
Good luck y'all!
