I'm trying to use this module with my Javascript project (not TypeScript) but I'm getting a dependency problem even though I have Jest installed. My NodeJs version is 10. Am I doing something wrong or is this only compatible with TypeScript?

ReferenceError: jest is not defined
    at Object.exports.mockRequest (.../myproject/node_modules/jest-mock-req-res/dist/index.js:1:246)

"devDependencies": {
    "jest": "^26.4.2",
    "jest-mock-req-res": "^1.0.2",
...

In my situation, I'm testing a controller as part of an ExpressJS-based server.

The call in my test looks like this: await RegistrantControllerModule.register(req1, res1);

Above that I have:

const req1 = mockRequest({body: testRegistration});
const res1 = mockResponse({});

The mockRequest works as I expect; body is used in the controller code for the test.

But if my controller succeeds, it should res.json an object, or if there are errors, res.status(x).json(errors).

Should I build out the responses I'm desire to see back in my test file from the res.json call in the controller?

For example in a test I expect to be successful:

  const res1 = mockResponse({
    json: {
      auth_token: "MyToken",
      info: {
        name: Tim,
        email: "[email protected]",
        websiteURL: "localhost",            
      }
    }
  });

The idea being that when I hit res.json in the controller, that mockResponse is returned to the test?

When I try that, I end up with TypeErrors for those values.

Examples showing how I might use this function in a test file would be most helpful.

Or, am I misunderstanding what this function is designed to accomplish?

Thanks!

Is there anything I'm losing sight of?
