AngularJS - e2e testing - Why does this by.css selector work? -

-

So I'm starting to break in javascript (& amp; jQuery) background in AngularJS; I'm vying through the tutorial I love it, and the way in which it is established. I am currently watching and I do not understand what works of a piece of code that I have tried to googling and poking through the document ... The launcher docs also do not feel anything for KC I could not understand how to search very briefly: / ... sorry if I'm just making it clear with some seriousness.

The code in the E2A test scenario is: 

  ('The main image should be swapped upon clicking on the thumbnail image', function () (element ( By (CSS. '(Phone: thumbs li: nth-child (3) img')). Click (); hope (element (by.css ('img.phone')) GetAttribute ('Src')). ToMatch (/img\/phones\/nexus-s.2.jpg/); Elements (By CSS ('Phone-Thumbs li: nth-child (1) img')) Click (); Expect (element (Via 'img.phone') getAttribute ('src')). ToMatch (/img\/phones\/nexus-s.0.jpg/);});
< P> which works on this page-html: 

  & lt; Ul class = "phone-thumbs ng-scope" & gt; li ng- repeat = "img in phone.images" class = "ng-scope"> lt; img ng-src = "img / Phones / nexus-s.0.jpg "ng-click =" set image (img) "src =" img / phone / Nexus-S.Z.JPG ">   This generated by NG-Markup

: 

  & lt; ul class = "phone-thumbs" & gt; & lt; Li ng- repeat = "img in phone.images" & gt; & Lt; Img ng-src = "{{img}}" ng-click = "set image (img)" & gt; & Lt; / Li & gt; & Lt; / Ul & gt;

I do not know why the element (by.css ('img.phone')) is functional. Based on the selector (and coming from jQuery) I expect to see a 'phone' class on the images ... but it's not there. Is the '.phone' reference something else?

I can see that .phone 'removal of part' ..... Alert: More than one element meet for locator. CSSSLactor ("IMG") - you may need to be more specific ', so how' specificity is provided '.phone "

thanks, Ben

You are just looking in the wrong place:

Checking to click on this thumbnail 

  // app / partials / phone-detail.html (line 9): & lt; Img ng-src = "{{img}}" ng-click = "set image (img)" & gt;

Creates this image: 

  // app / partials / phone-detail.html (line1): & lt; Img ng-src = "{{MainImageUrl}}" class = "phone" & gt;

Change the source of it img.phone is what you want. Documents for

by.css are here:

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
