I have a small silverlight app and when I "play" it, it just hangs in the browser. (Shows the spinner).
How can I debug this and find the cause?
Thanks
I would recommend the following...
Use Fiddler to see if there is any data that is coming/going to the server when you use this application.
Use another browser and see if the issue manifests itself
If it happens with all the browsers, then you can try capturing a dump of Internet Explorer and try to analyze it for the actual issue.
Is there a javascript exception? Open up the developer tools for your browser (F12 in IE and Chrome) to see the specific error message and error code. Once you have those, google them and voila!

Google analytics script fails to load with 500 error code on the website however if the link is opened in a new tab it's working fine.
Checked on MacOS BigSur Chrome, Firefox, Safari in normal and Incognito/Private mode without any active browser extension and got the same error.
Even the solution provided by NextJS https://github.com/vercel/next.js/tree/canary/examples/with-google-analytics does not work
Whatever I tried, I can't get rid of this error: GET https://www.googletagmanager.com/gtag/js?id=G-O5IW7EZ46Q net::ERR_ABORTED 500
Also tried to create simple static site to check is it NextJS issue or not and seems like it's not. https://codesandbox.io/s/nifty-currying-1hzu1?file=/index.html - this is the link to sandbox with google analytic script initialization and it fails as well with same error code.
Try to move the Google Analytics snippet in head section of the page.
I found the problem. The issue was in the Adguard software installed on the machine. Since the app was on OS level tt was automatically blocking across all browsers and private or incognito mode.
I'm using react with Rx.js library and I get this error in safari, but not the other browsers. Any idea why? Do I need to specify a setting to not look for map or what? Any clues would greatly help.
Appreciate it!
When you have the developer tools active the browser will request source maps. It is configurable in Chrome or Firefox but not in Safari (I actually went back to look for the setting right now and couldn't find it).
If you are in development mode, just copy the source maps to the folder where the minified file is otherwise don't worry about it as regular clients will not get this 404 (unless they are also using developer tools to explore your project).
I started exploring react-native. One thing which I want is should able to debug my app from chrome. I am having prior experience to cordova. Cordova renders app in chrome web view. I understand that with react-native it is not possible because react-native doesn't render app on web view.
There is an option react-native "debug in chrome". When I click this option, attached screenshot is getting opened. I enabled "pause on exception."
But nothing is happening. I am unable to see my app code at all.
I like to do step by step debugging. Is it possible? If so can some one tell how to do this?
You can definitely examine the source code, set breakpoints, etc in Chrome.
In the Sources menu, select debuggerWorker.js and then you should be able to see your project tree.
Any console.log in your code will print to the browser too. But I find the breakpoint inspection most helpful.
this is simple as you were doing in cordova.
try to put debugger; statement in your code while in debug mode.
It will set the breakpoint and you can then debug your application. No need to find out your files in debuggerWorker.js
I have a dotnet Selenium web driver app.
When I'm testing the page one of the things I need to confirm is that a flash object on the page has pulled correct content from a content store on my site. (i.e. the flash object should be loading content from /stuff/info.txt and including that content within the animation.)
As a human looking at this I can use the chrome network tab and see that /stuff/info.txt has been accessed.
How can I make Selenium execute a similar watch and see the network requests made by a web browser?
I did not wrote this, neither tested it however someone did it here: http://www.softwareishard.com/blog/firebug/automate-page-load-performance-testing-with-firebug-and-selenium/
Basically all the requests are exported via netexport and firebug plugins inside a HAR (Http ARchive file)
Please give us your feedback if you give it a try!
Cheers !
I assume you want to automate the process which the developer tools of browsers does. Something like firebug but for verification using Code.
I don't believe Selenium has such features. For now, you will not be able to achieve this.
Can anybody tell How to debug application in extjs in internet explorer and google chrome Browser? is it possible using Breakpoints to debug to check the values?
Thanks
There is a good article provided by sencha. check the section for internet explorer, http://www.sencha.com/learn/debugging-ext-js-applications
I have been forced to use IE8 in an application which works in Chrome and Firefox but fails often in IE8.
Debugging ExtJS in IE8 is nearly impossible if the problem is in the framework. IE8's developer tools hangs loading ext-all-dev.js
Also you can't get stack trace as in Chrome.
I had to put alert() calls in suspect lines and the whole process is a nightmare.
If you can avoid IE, do it.
Else be VERY VERY patient...
You can use the Developer Tools for your browsers. I don't use IE but I use Chrome's Developer Tools all the time! And yes you can do breakpoints, check values, etc..
