ReferenceError: BroadcastChannel is not defined using jest testing libray

I'm getting error while runing the jest test case using react-testing library

I have resolved it in following way

step 1: I have created config/jest.setup.js in root folder and pasted below code in jest.setup.js file

`function channelMock() {
    channelMock.prototype.onmessage = function () {}
    channelMock.prototype.postMessage = function (data) {
    this.onmessage({ data })
}
global.BroadcastChannel = channelMock`

Step 2: In package.js file we need to add this file path in following way

`"jest": {
        "setupFilesAfterEnv": [
            "./config/jest.setup.js"
        ]
    },`

Step 3: then you can run the test case using

`npm run test`

Issue resolved
