How to get around memory error with karma & phantomjs

由 泪湿孤枕 提交于 2019-12-03 06:54:03
问题 We're running tests using karma and phantomjs Last week, our tests mysteriously started crashing phantomJS with an error of -1073741819. Based on this thread for Chutzpah it appears that code indicates a native memory failure with PhantomJS. Upon further investigation, we are consistently seeing phantom crash around 750MB of memory. Is there a way to configure Karma so that it does not run up against this limit? Or a way to tell it to flush phantom? We only have around 1200 tests so far. We

Conditionally ignore individual tests with Karma / Jasmine

I have some tests that fail in PhantomJS but not other browsers. I'd like these tests to be ignored when run with PhantomJS in my watch task (so new browser windows don't take focus and perf is a bit faster), but in my standard test task and my CI pipeline, I want all the tests to run in Chrome, Firefox, etc... I've considered a file-naming convention like foo.spec.dont-use-phantom.js and excluding those in my Karma config, but this means that I will have to separate out the individual tests that are failing into their own files, separating them from their logical describe blocks and having

Currently, I have an exercise project up for getting comfortable with KarmaJS -- and Unit Testing, at large. The broad issue is that I really have no transparent view of what Karma is doing behind the scenes, and I can't seem to find adequate documentation in relevant areas. Without further delay...

Debug Tests in NG Test

问题 I am using Angular CLI and VS code but none of my breakpoints in my spec files seem to be getting hit when I run ng test? Do I need to do some config? 回答1: The other answers are completely valid answers but having been using Angular for around 18 months now I tend to do it in the browser - chrome tools! Run ng test then f12 and find the spec file via the webpack context. Add a breakpoint(s) and refresh and it will hit said breakpoints. As per screenshot 回答2: Angular 8.2.13 + Visual Studio

Angular2 NgModel not getting value in Jasmine test

由 孤街浪徒 提交于 2019-12-03 02:50:41
I am using template-driven forms in Angular 2, and I'm trying to develop them test-first. I've scoured this site and the rest of the internet and I've tried basically everything I can find (mainly bunches of tick() statements and detectChanges() everywhere in a fakeAsync) to get the NgModel attached to my input to pick up the value so it can be passed to my onSubmit function. The value of the input element sets properly, but the NgModel never updates, which then means the onSubmit function does not get the correct value from the NgModel. Here's the template: <form id="createWorkout" #cwf=
