921252 - XPCShell tests don't work with ChromeWorkers

Status: NEW

(Testing :: XPCShell Harness, defect)

Attachment: Patch that makes toolkit/devtools/server/tests/unit/test_pretty_print-*.js fail

I am re-writing the way that pretty printing in the debugger works so that the actual pretty printing is done inside a ChromeWorker.

With manual testing, my builds look good. My tests are passing in mochitest. However, the xpcshell tests are failing in nsHandlerService.js:

 0:01.24 file:///Users/fitzgen/src/mozilla-central/obj.noindex/dist/bin/components/nsHandlerService.js:891: exception: NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIProperties.get]

This is a smaller test case, but has a different failure message:

 0:00.33 TEST-UNEXPECTED-FAIL | /Users/fitzgen/src/mozilla-central/obj.noindex/_tests/xpcshell/toolkit/devtools/server/tests/unit/test_chrome_worker.js | Error: Failed to construct base URI! at /Users/fitzgen/src/mozilla-central/obj.noindex/_tests/xpcshell/toolkit/devtools/server/tests/unit/test_chrome_worker.js:8 - See following stack:

I don't know anything about ChromeWorkers. Maybe there's something they're expecting to exist that isn't configured properly in the xpcshell environment?
