Stubbing a non-function property const myObject = { 'hello': 'world' }; sandbox.stub(myObject, 'hello').value('Sinon'); console.log(myObject.hello); // Sinon sandbox.restore(); console.log(myObject.hello); // world sandbox.mock(); Works exactly like sinon.mock. If you need to replace a certain function with a stub in all of your tests, consider stubbing it out in a beforeEach hook. In this Sinon tutorial, Jani Hartikainen demonstrates how to make unit testing non-trival JavaScript code trivial with the help of spies, stubs and mocks. It’s a little extra work, but it’s ultimately harmless.

Verified non-issue with Sinon and Babel ... suspect you have fallen victim to the same issues as #1248 and #1648 that basically has to do with how one in a test can stub exports in a module that is used by another module. Tests are also the most concrete form of documentation of expected behavior, since other developers can figure out how to use your code by reading the tests. Sinon–Chai provides a set of custom assertions for using the Sinon.JS spy, stub, and mocking framework with the Chai assertion library. The JavaScript exception "is not a function" occurs when there was an attempt to call a value from a function, but the value is not actually a function. Stubbing a method on an object does not alter the method definition itself, but instead simply overwrites the value of the specified property to be a stub function. sandbox.useFakeTimers(); myFunctions = require('../index'); Creates a stub function for every function exported from the DLL. In some cases, you will need to modify the create function to use different mock implementations of getState and next.. Glossary#. Skeleton − This is the object which resides on the server side.
