require mock

function requireMock(path, mocks, [wipeCache], [clearCache]): any

• path: string path to the module file
• mocks: object where the keys are the mocks path relative to the module file and as a value the module implementation.
• wipeCache: string path that clears the require.cache before mocking
• clearCache: boolean to clear require.cache the changes made before importing the module.

example

lib.js

module.exports.libFN = () => {
  console.log("real function");
}

file.js

import {libFN} from "./lib";

module.exports.someFunction = function someFunction() {
  libFN();
}

file.test.js

import {requireMock} from "@miqro/test";

const mockedFile = requireMock("./file.js", {
  "./lib": {
    libFN: () => {
      console.log("fake function")
    }
  }
});

mockedFile.someFunction(); // prints "fake function"

const notMockedFile = require("./file.js");

notMockedFile.someFunction(); // prints "real function"

clearRequireCache

import {clearRequireCache} from "@miqro/test";
import {resolve} from "path";

clearRequireCache(resolve(__dirname, "src/"));

fake function

import {fake} from "@miqro/test";

const cb = fake(() => {
  return 1;
})

strictEqual(cb(), 1);
strictEqual(cb.callCount, 1);
strictEqual(cb.callArgs[0].length, 0);
strictEqual(cb.returnValues[0], 1);

// cb.reset(); // resets callCount, callArgs and returnValues
