Problem's testing opencv4nodejs

I’m using the matchFeature example from NodeJS but when i try to test the following error occurs in the const cv = require(‘opencv4nodejs’); line from the example.


● Test suite failed to run

TypeError: Cannot convert undefined or null to object at Function.keys ()

at Object. (node_modules/opencv4nodejs/lib/cv.js:63:8)
at Object. (node_modules/opencv4nodejs/lib/opencv4nodejs.js:11:79)

I think is a problem when loading the module, but i cant fix it. I’m using Jest for testing.

If i run the file with NodeJS, works without problems:

And if i run test with jest, gives the error above:
