Syntax Error when test component with SASS file imported

You have do define a mock for this kind of file by define moduleNameMapper in your jest settings.

We are using identity-obj-proxy. So install it with

npm install identity-obj-proxy --save-dev 

and add it your jest setting:

"moduleNameMapper": {
    "^.+\\.(css|less|scss)$": "identity-obj-proxy"
  }

If you have Babel in your stack, you can fix this in the right way using babel-jest

Just do npm i --save-dev babel-jest and in your jest settings file add:

"moduleNameMapper": {
  "^.+\\.(css|less|scss)$": "babel-jest"
}
