What is the oldest version of FireFox that this tool (JSErrorCollector) will work with?

Hi,

It could be great if you can make the JAR of 'JSErrorCollector' is available to the Maven central repository(http://search.maven.org/).

Excellent!
however does it support capturing warnings? I did try but it didn’t find any. Kindly please update.

Hello,

I cannot find any information about the licencing for this project? I was wondering what the licencing situation is?

Thanks,
Beccy

Thank you for the great API. Not long ago I've started use it and found several js-errors with it. When I wrote bug-reports about found errors I realized that it's not always obvious to find the page on which the js-error occured if we read errors after visit more than one page. Therefore it would be great if JavaScriptError class collects not only errorMessage, sourceName and lineNumber but also URL of the page with an error too.

I'm using WebDriver to start Firefox.
Then I use SikuliX to send keystrokes and mouse clicks.
After, I try to collect all errors by using:

JavaScriptError.readErrors(driver)

The result is always:

NoSuchWindowException Browsing context has been discarded

even though I haven't called driver.close().
How can I capture errors?

More info:

Versions:

• Firefox 66.0.5
• Java WebDriver 3.141.59

This trace could provide a hint of what is going on:

Is there anyway such that I can get all the console error logs (not only javascript) using this , maybe be tweaking this source code?

When I try to set up to use JSErrorCollector with a JavaScriptError.addExtension(profile) call, WebDriver hangs creating the driver with a stack like this:

Thread main
Thread.sleep(long) line: not available [native method]
NewProfileExtensionConnection.start() line: 111
FirefoxDriver.startClient() line: 244
FirefoxDriver(RemoteWebDriver).(CommandExecutor, Capabilities, Capabilities) line: 110
FirefoxDriver.(FirefoxBinary, FirefoxProfile, Capabilities, Capabilities) line: 188
FirefoxDriver.(FirefoxBinary, FirefoxProfile, Capabilities) line: 183
FirefoxDriver.(Capabilities) line: 100

To reproduce:

• Add the extension to the FF profile and get a driver with that profile (as shown on the sample code)
• Perform an event that will move to a different page (click a button in my case)
• Call JavaScriptError.readErrors(driver);

Notice that you'll start getting "window.JSErrorCollector_errors is undefined" exception intermittently.
I was able to get around this issue by sleeping for 100ms before making the JavaScriptError.readErrors(driver) call. I also tried with 50ms but it I still got the exception sporadically.

Here is the stack trace that I see:
[ERROR][2011-11-04 13:28:53,360][c.s.s.c.xxx]- [assertNoJSErrors] Unexpected exception on assertNoJSErrors()

Hello ! Thanks for your API!
As I can see in source code you use window.JSErrorCollector_errors.pump() , but when the code try to execute this command we can see next error in console
Permission denied to access property "pump"
Can you help with it ?

Thanks for the excellent plugin, we have been able to catch a bunch of issues with it by running it in our Selenium "get" calls!

It would be great if you could print the stack trace from the errors as well via the collector. Would implementing this be possible? On javascript, there are ways of retrieving the stack traces: http://stackoverflow.com/questions/3283576/how-to-trace-javascript-events-stack-trace

Currently errors are captured and persisted across pages. This is impacting our implementation as, when we want to check if any errors are present on the current screen, we are also seeing errors from all the previous screens. This makes it impossible to determine whether it is the current page or a previous page that has errors.

I was trying to capture error like https://docs.angularjs.org/error/$compile/multidir, via JSErrorCollector, but it is not able to capture this type of errors.
attached is the screen-shot of error I am trying to capture.

Tool fails to catch this error "TypeError: $(...) is null" on this page http://www.cnn.com/POLITICS/

As reported by FireBug.

I have two suspicions as to why this would be.

1. This isn't really a "JavaScript" bug, but rather a jquery bug.
   or
2. The error message occurs because the script was run before jquery was loaded. And firebug checks the script before rendering the page, while JSErrorCollector is checking afterwards.

I get following error after updating to webdriver 2.45.0 and Firefox 36:

It seems new Firefox doesn't like the script from JavaScriptError.readErrors line 134:
return window.JSErrorCollector_errors ? window.JSErrorCollector_errors.pump() : []
