How do I use stub in Sinon?

If you need to check that a certain value is set before a function is called, you can use the third parameter of stub to insert an assertion into the stub: var object = { }; var expectedValue = ‘something’; var func = sinon. stub(example, ‘func’, function() { assert. equal(object.

js. var glb_obj, test={}; var timer = 10; test. start_pool = function(cb) { timer–; if(timer < 1) { glb_obj = {“close”: true}; // setting object cb(null, “hello world”); } else { start_pool(cb); } } test.

Very simple, one just have to stub the function that will return the Promise, use the function returnsPromise. After that, you just have to the if the Promise will resolve and reject.

Stubs are functions or programs that affect the behavior of components or modules. Stubs are dummy objects for testing. Stubs implement a pre-programmed response.

Causes the original method wrapped into the stub to be called when none of the conditional stubs are matched. Causes the original method wrapped into the stub to be called using the new operator when none of the conditional stubs are matched. Like stub.callsArg (index); but with an additional parameter to pass the this context.

You can reset history of all stubs using sinon.resetHistory () Makes the stub call the provided fakeFunction when invoked. Makes the stub return the provided value. Causes the stub to return the argument at the provided index. stub.returnsArg (0); causes the stub to return the first argument.

Uncaught TypeError: Attempted to wrap undefined property sample_pressure as function I also went to this question ( Stubbing and/or mocking a class in sinon.js?) and copied and pasted the code but I get the same error.

As of Sinon version 1.8, you can use the onCall method to make a stub respond differently on consecutive calls. Note that in Sinon version 1.5 to version 1.7, multiple calls to the yields* and callsArg* family of methods define a sequence of behaviors for consecutive calls. As of 1.8, this functionality has been removed in favor of the onCall API.
