Js benchmark testing with settimeout1/3/2024 ![]() ![]() per-file overrides, like maybe you'd have something like this in package.Or maybe some other kind of "magic comment" that tells the runner how to behave? shebang configuration somehow, so you could put eg #!/usr/bin/env tap -timeout=120 in the first line of your file to have it run with that setting.It includes MockTimers with the ability to mock setTimeout, setInterval from globals, node:timers, and node:timers/promises. The nTimersToTime (msToRun) function would advance it by msToRun milliseconds. The new feature allows developers to write more reliable and predictable tests for time-dependent functionality. ![]() Instead of the timer running automatically, you would advance it manually. Tests should pass as fast as possible to detect errors earlier, improve developer. test/benchmarks/.taprc, and then only tests in that folder would have that config applied 1 Answer Sorted by: 38 The call to eFakeTimers () mocks every timer function with one that you must control. 6 Photo by Braden Collum Performance is an important criteria when choosing test-runner. per-folder configs, which would be really nice if you wanted to put, eg, timeout = 120 in.setInterval ( function, milliseconds) Same as setTimeout (), but repeats the execution of the function continuously. jonrsharpe at 22:07 Not what you originally asked, but instead of using a timeout, you can use the done event that Angular fires. timers: setTimeout, clearTimeout, setInterval, clearInterval: tracing: Support for instrumenting HTTP requests with tracing information. redis: Functionality to interact with Redis. Some config-overriding ideas I'm sort of toying with, other than "have the root tap object send an IPC message to adjust its timeout limit": Jest offers a set of Fake Timer utilities that can be used to test functions that rely on functions like setTimeout and setInterval. The two key methods to use with JavaScript are: setTimeout ( function, milliseconds) Executes a function, after waiting a specified number of milliseconds. at 22:06 Then I'd recommend you start your research there it's for testing asynchronous processes. Provides browser-level APIs to interact with browsers and collect frontend performance metrics as part of your k6 tests. (I'm looking into adding puppeteer for integration testing a few things, and omg, that's going to be so much worse than jsdom.) It'd be nice to only load those things conditionally. I am trying to do unit testing but on the code coverage report it is always showing that the code inside the setTimeout is not executing.Here is the code. I actually have a different need for per-test/per-folder config overriding, because I'm finding that a lot of tests in my current project are just dog slow due to loading jsdom and and stuff. I have a function containing setTimeouts. If the spawn doesn't finish in time, it gets SIGTERMed. You can either put: "tap": option used for each of those spawn calls. ![]() Performance tests with basic statistical computations. The problem is that the runner is still timing out the test suite itself after 30 seconds by default. In fact, Im sure the frustration of testing JavaScript has caused many an utterance of doh. ![]()
