1371589 - Debugging xpcshell tests with the jsdebugger is broken - breakpoints not hit

Status: RESOLVED INVALID

(DevTools :: Debugger, defect)

Description

[Mark Banner (:standard8)]

I'm trying to attach the debugger to an xpcshell-test and hit some breakpoints. I'm using the latest master, with the latest nightly.

./mach xpcshell-test --jsdebugger toolkit/components/places/tests/bookmarks/test_405938_restore_queries.js

It starts up and lets me connect, however when I let it run the test no breakpoints are hit, no debugger statements are hit, which means I can't find out what's happening.

When it connects, there's this message on the xpcshell console output:

 0:04.76 LOG: Thread-1 INFO "Failed to initialize breakpoints: TypeError: query object's 'source' property is not undefined nor a Debugger.Source object

Sorry for the noise, this is totally my fault, I was no-where near hitting the breakpoints I thought I should have been.
