![]() Here is the syntax for the setTimeout () method. To add to the complication, my code is server-side, so I can't just spyOn ( window, 'setInterval' ). setTimeout () is a method that will execute a piece of code after the timer has finished running. The setTimeout()method takes two parameters: a function to be executed and a delay time in milliseconds. Testing setTimeout & setInterval With Jasmine-Node 30 October 2015 Jasmine No de Jasmine has a very complicated way of testing setTimeout and setInterval that I, frankly, don't understand very well. The nTimersToTime (msToRun) function would advance it by msToRun milliseconds. ![]() Instead of the timer running automatically, you would advance it manually. I've never done any testing with jasmine, but I think I understand your problem. You need to import the benchmark library: const Benchmark require ('benchmark') object, with a name if you like: const suite new Benchmark. A string of code, on the other hand, cannot be passed to be executed. Getting started is easy simply install Benchmark.js by running the following: npm i -save-dev benchmark. Ie tTimeout() is handled on a file level. This only affects the test file from which this function is called. The nTimersToTime (msToRun) function would advance it by msToRun milliseconds. From the tTimeout() docs: Set the default timeout interval for tests and before/after hooks in milliseconds. ![]() Instead of the timer running automatically, you would advance it manually. It is similar to the JavaScript API’s tTimeout() function in browsers. The call to eFakeTimers () mocks every timer function with one that you must control. ![]() 1: Actually wait in the test 250+1 ms in a setTimeout(), then check if the element actually disappeared.Ģ: use fakeAsync() and tick() to simulate time in the test - a tick() will resolve the setTimeout in the original close(), and the check could happen right after in a fixture.whenStable().then(.). Feb 23 Listen Share Improving Web Performance What’s a setTimeout() setTimeout()is a method in JavaScript that allows you to schedule a function to be executed after a specified amount of time has elapsed. 1 Answer Sorted by: 38 The call to eFakeTimers () mocks every timer function with one that you must control. setTimeout() setTimeout() can be used to set code execution after a certain period of time has passed (in milliseconds). ![]()
