My xulrunner-sdk-33 subfolder also does not have a 'b2g' subfolder. Nor does the 'obj-x86_64-unknown-linux-gnu' subfolder under my b2g32_v2_0 hg tree.

Doing this in xulrunner-sdk: # ln -s bin b2g ...lets the mochitest runner progress to here: From _tests: Kept 12572 existing; Added/updated 0; Removed 0 files and 0 directories. waiting for system-message-listener-ready... ...done MochitestServer : launching [u'/home/mikeh/dev/mozilla/b2g/051_emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/b2g/xpcshell', '-g', u'/home/mikeh/dev/mozilla/b2g/051_emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/b2g', '-v', '170', '-f', u'/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/httpd.js', '-e', "const _PROFILE_PATH = '/tmp/tmpQh_M0i'; const _SERVER_PORT = '8888'; const _SERVER_ADDR = '192.168.230.153'; const _TEST_PREFIX = undefined; const _DISPLAY_RESULTS = false;", '-f', '/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/server.js'] runtests.py | Server pid: 9856 runtests.py | Websocket server pid: 9859 INFO | runtests.py | expected to find ssltunnel at /home/mikeh/dev/mozilla/b2g/051_emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/b2g/ssltunnel Automation Error: Exception caught while running tests Traceback (most recent call last): File "/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/runtestsb2g.py", line 332, in run_remote_mochitests retVal = mochitest.run_tests(options) File "/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/runtestsb2g.py", line 117, in run_tests self.startServers(options, None) File "/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/runtestsb2g.py", line 209, in startServers MochitestUtilsMixin.startServers(self, options, debuggerInfo) File "/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/runtests.py", line 550, in startServers self.sslTunnel.start() File "/home/mikeh/dev/mozilla/b2g/051_emulator/objdir-gecko-b2g32_v2_0/_tests/testing/mochitest/runtests.py", line 737, in start exit(1) File "/usr/lib/python2.7/site.py", line 375, in __call__ raise SystemExit(code) SystemExit: 1 Stopping web server Stopping web socket server Stopping ssltunnel

So here's what does work (thanks to a tip from bug 1066042): # hg clone http://hg.mozilla.org/releases/mozilla-b2g32_v2_0/ $MC/b2g32_v2_0 # cd b2g30_v2_0 # ./mach build # cd obj-x86_64-unknown-linux-gnu/dist # ln -s bin b2g # cd $B2G # export XULRUNNER_DIRECTORY=$MC/b2g32_v2_0/obj-x86_64-unknown-linux-gnu/dist # ./mach mochitest-remote $PATH_TO_TEST_SCRIPT

The code that finds the --xre-path lives here: https://github.com/mozilla-b2g/B2G/blob/master/tools/mach_b2g_bootstrap.py#L101 It used to be the case that it returned those xulrunner-sdk dirs, but ever since bug 1002545 it was changed to download the files from a recent b2g_desktop build instead. On trunk, it should find a dir in '$B2G/gaia/b2g_sdk'. I think what's happening here is that you're building on an older branch and are running into bug 1002545 (no ssltunnel). I just tested on trunk and things work. You could probably simplify your workaround by just setting XULRUNNER_DIRECTORY=$B2G/gaia/b2g_sdk/<ver>/b2g and USE_LOCAL_XULRUNNER=1 in your .userconfig. I don't think there's any easy fixes here without backporting a whole bunch of stuff. I'd propose WONTFIX'ing and just sticking to the workaround for now, but I'll leave that up to you.
