Jest: Error shows the wrong line number

[zgorizzo69]

configuration

$ npx truffle version                          
Truffle v5.1.43 (core: 5.1.43)
Solidity - ^0.7.0 (solc-js)
Node v12.16.3
Web3.js v1.2.1

Behaviour

The error output always shows a wrong line number when Jest is used instead of truffle mocha/chai if you run the test it will display an error at Object.<anonymous> (tests/anchorV0.spec.js:17:19) while the actual error is located at line 23 where the expect statement is. Moreover if you add extra blank lines in the test file the error line will be different ...

Expected behaviour

the error output should display the actual line where the error is raised in our example it would be line 23

How to reproduce

git clone the repo https://github.com/zgorizzo69/truffle-OZ-Jest-Fail and run yarn && yarn test

Thank you for reporting @zgorizzo69.

I'd be very surprised if this error was caused by Test Environment. Can you share what makes you think that it could be this library?
