// 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.
