The automock module is imported from a specific file path, allowing for code mockups to be created. The automock.mockValue function is used to create a mock value, which returns a function that logs its name parameter to the console when called.

Code Breakdown

Importing Automock

var automock = require('../../universal/src/imports/automock.js');

• This line imports the automock module from a specific file path.

Mocking a Value

automock.mockValue({}, {
  stubCreator: function (name) {
    console.log(name);
    return function () {
    }
  }
})

• automock.mockValue is called with an empty object {} as the first argument.
• The second argument is an object containing a stubCreator function.
• The stubCreator function takes a name parameter and returns a new function.
• The returned function is empty, as indicated by the lack of any implementation (i.e., return function () { }).
• When this function is called, it will log the name parameter to the console, but it will not perform any actual action.
