How to debug PhantomJS when running through Karma

阅读更多关于 How to debug PhantomJS when running through Karma

问题 I test through Jasmine, Karma and a variety of browsers. I'm currently debugging a test that fails only in PhantomJS. I'd like to debug this call, so I've setup a custom PhantomJS launcher in karma that runs it with the debug port open. I'm able to access the remote debugger in Chrome through that port, however, it seems to know nothing about any of my test files. It reports an "about:blank" and a "localhost:9876" (the karma server that Phantom is hitting) but when I try to debug that

问题 I am trying to make an isolated test case to experiment with PhantomJS localStorage behavior, but in my testCase, localStorage does not appear to be persistent. Here is the PhantomJS script: var page = require('webpage').create(); page.open('http://localhost:8080/myapp/test.html', function() { var x; x = page.evaluate(function() { return localStorage.getItem("foo"); }); console.log(x); phantom.exit(); }); When test.html has a call to localStorage.setItem("foo", "bar") the script displays "bar

How to take a snapshot of a section of a web page from the shell?

阅读更多关于 How to take a snapshot of a section of a web page from the shell?

问题 I have a section of a web page that I need to take a gif snapshot of at a given time interval. The snapshot needs to be full page size resolution, however as I said, it only goes to a certain place on the page (in this case it's after a table). What would be the best way to grab a page snapshot image image like this? I'd like to just throw it into a cron job and forget it, but I'm not readily seeing a tool that would make quick work of this. SOLUTION: As per the @Eduardo's excellent direction

阅读更多关于 List child elements for a Capybara/Poltergeist element

问题 I've searched around and I can't find a way to do this. We are running Capybara tests with the Poltergeist driver in cucumber features on an EmberJS/Rails app. I can't use page.driver.debug because I'm running inside a headless vagrant instance, so that troubleshooting is not available to me, but screenshots work, and a Chrome dev tools inspect on the page in question shows the right elements. I have a cucumber scenario that's failing, and it's because the find isn't working. My test looks

Testing React Apps with Phantom/Casper

阅读更多关于 Testing React Apps with Phantom/Casper

I'm diving into functional testing and attempting to get a few simple tasks working. The app is built in ReactJS and I've decided to use Phantom/Casper. The problem is that even the most basic tasks fail. In short, is there a trick for testing React apps with Phantom/Casper? I've installed Phantom (v.2.1.1) and Casper (v1.1.0-beta5). As a first attempt I created a simple script to capture an image: capture.js var casper = require('casper').create({ viewportSize: { width: 1024, height: 768 }, verbose: true, logLevel: "debug" }); casper.start('http://localhost:9494', function() { console.log(
