karma-stacktrace's Issues

Update Stacktrace.js to the latest version

https://github.com/stacktracejs/stacktrace.js/releases/tag/v2.0.0

Prevent handling `global failure` in QUnit

karma-stacktrace duplicates errors in QUnit since Karma 1.0.0 because of adding errors throwing in debug.html for each failed unit tests, QUnit handles it as a global failure:

Karma throwing error without loosing stack trace: karma-runner/karma@8a515ae

QUnit: https://github.com/qunitjs/qunit/blob/baff17dbc12168c139dc339ba1e0d07e4a7e8215/src/core/onerror.js#L17

Failed to execute 'importScripts' on 'WorkerGlobalScope': The URL 'undefined' is invalid.

After updating from karma 4.1.0 to 6.3.4, I get this error:

Electron 12.0.2 (Node 14.16.0) ERROR
  An error was thrown in afterAll
  Uncaught SyntaxError: Failed to execute 'importScripts' on 'WorkerGlobalScope': The URL 'undefined' is invalid. thrown

The code that tries to execute importScripts is from karma-stacktrace here:

karma-stacktrace/lib/stacktrace.js

Lines 185 to 195 in a20cf40

    
             function buildWorkerScript(stacktracejsURL) { 
        
               return `importScripts("${stacktracejsURL}"); 
        
                 var sourceCache = {"${currentPage}": " ","<anonymous>": " "}; 
        
                 onmessage = function (message) { 
        
                   StackTrace.fromError({stack: message.data}, { sourceCache: sourceCache}) 
        
                       .then(function (stackFrames) { 
        
                           stackFrames.forEach(function (s) { s.serialized = s.toString(); }); 
        
                           postMessage([message.data, stackFrames]); 
        
                       }); 
        
                 };`; 
        
             }

where stacktracejsURL is undefined.

Any idea why updating karma breaks karma-stacktrace or causes this error to show up?

Use onerror to detect errors instead of framework-specific hooks

Use window.addEventListener('error', ...) instead of framework-specific logging hooks. This should allow to support any frameworks supported by Karma and log all errors only once.

Also update to https://github.com/stacktracejs/stacktrace.js/releases/tag/v2.0.0

Use window.parent instead of / alongside with window.opener

window.opener can be used to detect if the page is running in a popup / new window. But if you want to detect if it's running in an iframe (which is the default in Karma) you should use window.parent !== window.
