Protractor: launch chrome with network throttling enabled

由 落爺英雄遲暮 提交于 2019-12-19 03:19:25
问题 The network throttling feature from Chrome DevTools is available in ChromeDriver-2.26+ according to this issue. How can I specify this in our protractor config file? Based on searching around, I've tried variations of a couple things in the config file. I've added a networkConnectionEnabled property and a prefs block to chromeOptions, as below. (Note that I didn't do them both at the same time.) multiCapabilities: [ { 'browserName': 'chrome', 'platform': 'ANY', 'networkConnectionEnabled': {

由 别说谁变了你拦得住时间么 提交于 2019-12-18 15:48:24
问题 My first post here =]. I'm building a chrome extension and I'm using a setTimeout recursively. I noticed that if I set it to up to 13secs, it works, but if I set it to 14secs+ it won't work.

Customise the look of the Chrome web inspector

由 倖福魔咒の 提交于 2019-12-18 13:37:11
问题 I've grown tired of the multitude of issues I seem to hit on a daily basis with Firefox and I'm trying once again to switch to Chrome. One of the things that frustrates me is the layout of the tabs in the inspector. In firebug they are all along the top so if I want the metrics of an item it's incredibly simple. In Chrome I'm forever scrolling up and down. Is there anyway to change the way this works? All I want to do is change the layout to something a little similar to Firebug. Cheers! 回答1:
