user interface - Automated testing for OpenGL application -

-

I have a Java application that uses JOGL to provide a large part of the GUI.

Use JOGL if any device you know, or has used, that can automate the test of OpenGL applications (or more specifically, using those people)

Just to update: The tool can run on either Linux or Windows.

I have written unit-test for C ++ (Qt on Linux) & amp; Before OpenGL, I have no reason to know that it should not work for Java also.

Things to do for me are:

  • Abstract Your OpenGL Provider Provider Your Remaining Code Is Free In My case, the main app uses QT's QGL Widget , But unittests has used a pbuffer-based one that I can create with no Windows installation (except for a specified X11 DISPLAY). Later I have added an "offscreen messa" (pure software OpenGL implementation) so that they can work on the headless build machine without any GPU.

  • Keep your OpenGL code free In my case of OpenGL "rendering engine" in your case, I did not know anything about QT class (such as mouse events). Define your own testable API which is not associated with any specific GUI concepts, and writes a test for it.

  • In unittests, read the content back using framesbuffers using glReadPixels or hit them with some claims, which should be pixel specific value, or regression testing Go down the route and compare framebuffer capture with a stored image that you know (either by manual verification it is generated from any other reference model).

  • Allow a little smoke in any image regression test; The implementation of most open GLs produce a slightly different output.

  • (I did not do this, but ...) ideally you want to be able to test the GUI layer by ensuring that your rendering engine in response to the GUI activity Creates the expected sequence of calls if this happens, and due to the above tests you have full faith in your render layer ... OK, there really is no need to render. To use for GUI testing, create a proper duplicate object of your rendering layer (I imagine a test like "Drag the mouse from here, one specifically calls the rendering layer to set the matrix". Stuff like.)

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

-
I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
