So there are two things going on which I have no clue and if someone can help that would be awesome.
I am doing automation using Selenium WebDriver in conjunction with VS2010 (C#) and I am using the PageObject pattern, which has really been helpful in constructed clean, organized code. Anyway, here are my two issues:
When I Debug my code the automation runs perfectly with the desired results at the end. But when I enter a breakpoint and step into the code, it gives me an error message stating "There is no source available - There is no source code available for the current location" Then the message looks like it is looking in my directory for a particular class file and it gives me a bunch of error messages and the last line says: The debugger could not locate the source file c:\Projects\WebDriver\trunk\dotnet\src\WebDriver.Support\PageObjects\WebElementProxy.cs.
Again when I run through the program with no breakpoints it's fine. But once I enter a breakpoint and step into the code, it gives me that error like it's looking for a particular class. I have all .dlls referenced to the project so I am not sure what is going on there.
When I run the code in Chrome, everything seems to work fine. But when I try to run it using FireFox, it cannot seem to locate the first button. I have my code set up as:
//Get A Quote Button Control by ID
[FindsBy(How = How.Id, Using = "bt_ContinueWelcome")]
[CacheLookup]
public IWebElement GetAQuoteButtonId;
So Chrome will read it fine but not FireFox, and I have not tried IE.
Any help for the above would be greatly appreciated. I want to start inserting validation but I need to get over these hurdles first - thank you

I have written a code for Web page. The process requires me to click on a weblink which opens up a new window, then perform some operations on the browser window. Then I close the new browser. This is repeated multiple times in the code. All the elements on all the browser windows are normally identifiable using the object spy. However, intermittently during run time when a new browser window opens up the elements on the page are not getting recognized (hence it throws errors). When i go into the debug mode and try using the object spy the maximum identification i can capture is Browser(<>).Page(<>). Nothing in the page is getting recognized.
Now if i close this browser and reopen it and check again, the elements on the page are getting captured by the object spy and i can continue with my script execution. Sometimes I have to close and reopen multiple times for it to work.
Is there any way to handle this scenario. check for object identifications on the run time maybe. Dunno if it this is any relevant but i am not making use of the OR in my project.
Thanks in advance.
This sounds like a bug in UFT and you should contact HP's support.
A workaround if you know where the problem is probable to appear is to add Browser("<name>").RefreshWebSupport. This is an undocumented feature of UFT that sometimes helps in cases like this.
I'm currently (trying) to develop an app with Worklight Studio 5.0.6 and Dojo (Mobile) 1.8.3. I have a really hard time to to find a proper method for debugging. After waiting 5-10 minutes for the build an deploy-process on the server, an error usually looks like this in the Chrome debugger:
How am I supposed to track down this error in MY source? The whole stack trace consists entirely of Dojo code which generates an absolutely useless error message after 20 abstraction layers.
Seriously, how do you guys handle this in real life? What methods do you use for debugging Dojo-driven apps in the browser?
spyro
For dojo.parse errors, I find it useful to pause the Chrome debugger on all exceptions (the purple icon on your screenshot, should be blue). You usally get more details about the cause of the error, the name of the DOM node being parsed, etc. in the first exception being raised.
Rémi.
Debugging dojo based application should be the same as debugging any javascript application.
Usually I will follow these steps:
add console.log() somewhere in code: this is fast and most of time this is enough.
set breakpoint in debugger: if step 1 is not enough, you can base on error information to set breakpoint before error line, then step in or step out.
comment out recently changes: for some error which is hard to find the error line, for example, parse error in your case, the good way is comment out your recently changes one by one till back to your last working version. Or, return to your last working version, then add code back one by one.
Create a simple application to reproduce the error : if your application is very complicate and it is hard for you to follow above methods, you can try to create a new application which mimics your current application but with simple logics and try to reproduce the error.
Based on experience : Some errors, for example, extra ',' in the end of array which works at chrome and firefox, will report a nonsense error information at IE. Debug these kinds of errors is very difficult, you can base on your experience or do a google search.
Did you provide isDebug: true in your dojoConfig? Also, try to see if the same occurs in other browsers.
Update: I recently discovered that there are issues with Google Chrome and Dojo debugging and I think it has to do with the asynchronous loading of files. As you can see in the provided screenshot of #spyro, the ReferenceError object is blank (which you can notice because of the empty brackets {}). If you want to solve that, reopen the console of Google Chrome, (for example by tapping F12 twice). After reopening the ReferenceError should not be empty anymore and now you can expand that object by using the arrow next to it and get a more detailed message about what failed.
Usually what I do in situations like that is to place a breakpoint inside the error callback (line 3398 in your case) and then look into the error variable ("e").
I am not sure how familiar you are with the Web Inspector, but once you hit the breakpoint open the Web Inspector 'console' and check for the error properties "e.message" and "e.stack" (just type in "e.message " in the console).
Also, during development it is better to avoid Dojo optimization / minification, which greatly improve your debug-ability.
Bottom line is to try to place the breakpoint before the error is thrown.
I am writing a Google Chrome extension. One of my content scripts has a little bug that I can't find and the Google Chrome debugger appears to be useless for this purpose. The code stops on an Uncaught typeError: Cannot set property 'value' of null. I can see this by opening the debugger and viewing the console after the code fails. But my content script does not appear in the list of scripts shown in the debugger at this point. There are a lot of scripts shown there, including a big block of scripts in light blue. But none named "profile.js" which is my content script.
I tried "location.reload(); but it simply returns "undefined." I'd love to step thru this code and find the problem but I can't figure out how to do it. I've set alerts to try to track the problem but once I click on the alert, the script continues with no opportunity to invoke the debugger. Based on the result of the alert experiment, it appears the code is failing at the very end. I presume the code is finished by the time the error is caught and the script is no longer available to the debugger.
I tried adding this line to the script: "debugger;" to try and force the debugger to open but there is no change whatever to the execution of the code. It fails as usual and as usual I can open the debugger, find the console message and the big list of scripts that does not include mine.
How can I pause execution of the code using a line in the code itself? I just want to stop execution of the code at the beginning, invoke the debugger, set up some breakpoints, resume execution and monitor some variables. That seems like a pretty simple and do-able request.
Any ideas?
I have a console app, and a class library.
I'm making changes to the class library (adding new methods, changing what methods do, etc) - Just regular stuff - nothing fancy.
In the console app - I'm calling methods from the class library - obviously to test the class library methods - again no rocket science here!
Both projects are targeting Framework 3.5 (This is because I have Sharepoint 2010 being referenced in class library)
Now:
When I debug the app using F5 - I've set a break point in the console app. When it steps through to the class library (using F11) I get a message saying source code has changed in a pretty lengthy dialog. If I click cancel - it then says No source code available.
I have found a work around to right click on project in solution explorer, then select debug -> create new instance.
But this is strange, never had this issue before, what can I do to get the debugger behaving normally. By normally I mean every time I hit F5 it should understand that the source code in the class library will almost surely have changed and I don't want any nags about this, or break point conditions never being met.
On a side note, never had this issue before, so an explanation as to why its happening would help a lot.
Thanks in advance
Update: the short version
Why do I have to manually tell the debugger to "create new instance" everytime I want to debug? If I don't hitting f5 debugs the source code of the last successful debug session.
Maybe your console application doesn't build second project? Try verifying that newest version of library is called.
I get the infamous "Dialogs must be user-initiated" Security Exception when I try to print some stuff in Silverlight. As you can see, the dialog is as user-initiated as can be:
John Papa couldn't help me much out neither, because I don't have any breakpoint set. Mr MSDN thinks it could also be that I'm just taking too long, but this is a demo application just as simple as can be.
Any ideas? I guess it's a Visual Studio quirk, maybe some extensions interfering, as things seems to work when I launch the application outside of it. I first thought maybe the Code Contracts are interfering with their IL weaving, but they are deactivated for this project.
Update: This is just a simple Silverlight application that runs locally from the file system. When I do "Start debugging", Visual Studio creates a hosting HTML file containing the Silverlight app in the Debug resp. Release folder of the project, launches the Internet Explorer with that HTML file and attaches the debugger to it.
Update 2: I also get the same error when I create a web project to host the Silverlight app and create a virtual directory for it on IIS.
I might also want to add that I don't have problems with printing in other Silverlight projects regardless of their hosting scenarios.
Update 3: I downloaded FireFox and it works, I don't get the error when I debug with it. So it seems to have to do with my IE8. I uploaded the solution:
http://dl.dropbox.com/u/10401470/Code/Demos/PrintingDemo.zip
I wonder if anyone can reproduce?
Anyone got an idea to which team I should file a bug report? Silverlight team? IE team? VS Debugger team?
I'm able to reproduce this. You have handled the Click twice, once in XAML another time in code. See your MainPage.xaml
<Button x:Name="PrintButton"
Content="Gotta print 'em!" Margin="8"
Click="PrintButton_Click" />
Don't feel bad about it. I did it last time through a misplaced Print inside a loop.
I've also experienced this strange behaviour. A standard button click event immediately invoking an OpenFileDialog. It would frequently generate the same error when being debugged but would eventually be coaxed in to working when the button is clicked several times.
However when built as a release (or perhaps simply by running the same Xap without a debugger attached to the browser) the problem would go away.
Try to remove
if(SightPaleceListBox.Items.Count > 0)
I had the same problem and found out that the reason was this following line:
cnvsMain.Children.Remove(PrintPagePlaceHolder);
cnvMain is on the page that the user pushed the Print button on (I was trying to remove it from that page in order to add it to the canvas that I was going to print).
My tip: try to comment rows one by one, until you find what row causes the problem. Than try to work around it.
