This bug is also reported for primeng team: primefaces/primeng#14085 |

Bump. Have been seeing this in my workspace and trying to get to the bottom of it |
|
The Problem seems to be the CSS parser "cssom" that jsdom uses. I does not support NV/CSSOM#109 (comment) Here is one of the pieces of code that fails for me: This is a copy of the comment on the PrimeNG issue: primefaces/primeng#14085 (comment) |

I wonder if it's possible to parse CSS before JSDOM processes it. That might solve the issue |
|
We had the same problem in our Angular application and the source of it was as described primefaces/primeng#14085 (comment). Our solution after trying out unsuccessfully vitetest integrating over analogjs as a replacement for jest, as suggested here, we resolved our issue with the following solution: npm install --save-dev happy-dom For alternative configurations one can checkout the readme here.

I was having the same issue using Primereact + Nextjs and this solution works, thank you! |
|
Switching to an alternative test environment (happy-dom, in this case as suggested above) solved this for me. Test execution speed seems similar, nothing has broken. Only thing I'd like now is to make jsdom a peer dependency rather than a dependency of this package so we can choose to opt out of it. |

put this in let consoleSpy: jest.SpyInstance;
beforeAll(() => {
consoleSpy = jest.spyOn(global.console, 'error').mockImplementation((message) => {
if (!message?.message?.includes('Could not parse CSS stylesheet')) {
global.console.warn(message);
}
})
});
afterAll(() => consoleSpy.mockRestore()); |
Version
13.1.4
Steps to reproduce
Steps which I made to prepare repo:
Expected behavior
Should work without any errors
Actual behavior
Error is shown in console:
Additional context
In one of v16 releases PrimeNg has used @layer at-rule inside their css stylesheets. It looks like jsdom for some reason cannot parse css, which contains @layer {} at-rule - I found this issue reported: jsdom/jsdom#2177.
Adding some trick to stub console.error to not show this error works, since it is not preventing tests from pass.
