sinon

问题 I am new in node.js. I am writing code in node.js for postgresql using pg and pg-native for serverless app. I need to write unit test for it. I am unable to mock pg client using jest or sinon.

问题 As per suggestion in question enter link description here I mock readFileSync and mocked my outer function now I want to verify if the variables value is set as expected or not file.js const fs1 = require('fs'); let param; module.export = { test, param } function test (outputParam) { param = fs1.readFileSync(outputParam); } I have stubbed this readFileSync and it returns specified file content as shown in the test below When I run the test I want to see the variable param has the file content

问题 i need to test this function : //user.js function getUser(req,res,next){ helper.get_user(param1, param2, (err,file)=>{ if (err) return next(err);} my test function : it ("failed - helper.get_user throws error",sinon.test(function () { var req,res; var get_user = this.stub(helper,"get_user") get_user.yields(new Error("message")); var next = sinon.spy(next); user.get_user(req,res,next); expect(next).to.have.been.calledWith(new Error("other message")); })) for my assertion I'm using sinon-chai

问题 I'm trying to test a simple component that uses action delegation. I want to test that a certain action is sent to the actionDelegate of a component. I was thinking of using Sinon to check that the action was being sent, but I can't work out how to replicate the structure that Ember uses to send its actions to its delegates/targets. What structure would my sinon "spy delegate" object take in order for me to check that the component is delegating the event using "send" when the user clicks on

问题 I am trying to stub a method using sinon.js but I get the following error: 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. Here is my code: Sensor = (function() { // A simple Sensor class // Constructor function Sensor(pressure) { this.pressure = pressure; } Sensor.prototype.sample_pressure = function() { return this.pressure
