Error when use lottie-web and run test reactjs with Jest.

I’m using lottie-web library in my reactjs project. When I run test, initially I got error:

Not implemented: HTMLCanvasElement.prototype.getContext (without installing the canvas npm package)

I’ve reseached and fixed it by install jest-canvas-mock:

        "setupFiles": [
            "<rootDir>/tests/setupJest.ts",
            "jest-canvas-mock"
        ],

But I’ve got new error: Error: connect ECONNREFUSED 127.0.0.1:80 😦

Instead of mocking the module, you can also try importing jest-canvas-mock on your setupTests file

hi, I think that for testing purposes you’d probably want to mock the lottie library. Otherwise it will try to load the animation through the network, which is probably what is happening in this case.
