// Utility script for writing worker tests. In your main document do:
//
// <script type="text/javascript" src="worker_driver.js"></script>
// <script type="text/javascript">
// workerTestExec('myWorkerTestCase.js')
// </script>
//
// This will then spawn a worker, define some utility functions, and then
// execute the code in myWorkerTestCase.js. You can then use these
// functions in your worker-side test:
//
// ok() - like the SimpleTest assert
// is() - like the SimpleTest assert
// workerTestDone() - like SimpleTest.finish() indicating the test is complete
//
// There are also some functions for requesting information that requires
// SpecialPowers or other main-thread-only resources:
//
// workerTestGetVersion() - request the current version string from the MT
// workerTestGetUserAgent() - request the user agent string from the MT
// workerTestGetOSCPU() - request the navigator.oscpu string from the MT
//
// For an example see test_worker_interfaces.html and test_worker_interfaces.js.
