Wallaby not working with jasmine callFake

[joilson-cisne]

Issue description or question

Wallaby seems not to be working with jasmine callFake. The argument of the "fake" function is always undefined.

The test below passes when I run with jasmine directly, but it breaks when running with wallaby. Does anyone had this problem before?

it('test callFake and wallaby', async () => {
      // Arrange
      const myObj = {
        myFunc: (a) => a + 1,
      };

      spyOn(myObj, 'myFunc')
        .and.callFake(arg => arg);
      
      // Act
      const result = myObj.myFunc(1);

      // Assert
      expect(result).toBe(1);
    });

Wallaby.js configuration file

module.exports = (wallaby) => {
  return {
    files: [
      'src/**/*.js',
      'migrations/*',
      'test/_helpers/*',
      'seeds/*',
      'config/*',
      { pattern: '.env', instrument: false },
    ],

    tests: [
      'test/**/*.spec.js',
    ],

    compilers: {
      '**/*.js': wallaby.compilers.babel(),
    },

    testFramework: 'jasmine',

    env: {
      type: 'node',

      params: {
        env: 'NODE_ENV=test;MONGODB_CONQUERY=mongodb://localhost:27017/athena-test',
      },
    },
    workers: {
      initial: 1,
      regular: 1,
      restart: true,
    },

    setup: (/* wallaby */) => {
      require('dotenv').load({ path: '.env' }); // eslint-disable-line
      require('./test/_helpers/dropDatabase'); // eslint-disable-line
    },

    teardown: (/* wallaby */) => {
    },
  };
};

Thanks for the report. Apparently you are using Jasmine 2.9, because your code is working as expected in Jasmine 3.x. The bug in Jasmine 2.x support was introduced recently when adding Jasmine 3 support in wallaby.

The regression is fixed and the fix had juts been published in the latest core (or update your Jasmine version to 3.x).
