STR: 1. Build the B2G emulator based on the master branch. I built in debug mode, not sure if it's relevant. 2. Run "./mach mochitest-remote" Expected results: Mochitests run. Actual results: See output below. botond@botond-Precision-T1650:~/dev/mozilla/b2g-emulator > ./mach mochitest-remote From _tests: Kept 11594 existing; Added/updated 0; Removed 0 files and 0 directories. waiting for system-message-listener-ready... ...done MochitestServer : launching [u'/home/botond/dev/mozilla/b2g-emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/bin/xpcshell', '-g', u'/home/botond/dev/mozilla/b2g-emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/bin', '-v', '170', '-f', u'/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/httpd.js', '-e', "const _PROFILE_PATH = '/tmp/tmpm1XFYD'; const _SERVER_PORT = '8888'; const _SERVER_ADDR = '10.242.24.73'; const _TEST_PREFIX = undefined; const _DISPLAY_RESULTS = false;", '-f', '/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/server.js'] runtests.py | Server pid: 11801 runtests.py | Websocket server pid: 11803 INFO | runtests.py | expected to find ssltunnel at /home/botond/dev/mozilla/b2g-emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/bin/ssltunnel Automation Error: Exception caught while running tests Traceback (most recent call last): File "/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/runtestsb2g.py", line 332, in run_remote_mochitests retVal = mochitest.run_tests(options) File "/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/runtestsb2g.py", line 117, in run_tests self.startServers(options, None) File "/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/runtestsb2g.py", line 209, in startServers MochitestUtilsMixin.startServers(self, options, debuggerInfo) File "/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/runtests.py", line 555, in startServers self.sslTunnel.start() File "/home/botond/dev/mozilla/out-of-tree-objdirs/gonk-emulator/_tests/testing/mochitest/runtests.py", line 742, 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 After talking to :jmaher and :ctalbert I worked around the problem by downloading a test zip from ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/ and copying everything from the 'bin' directory into /home/botond/dev/mozilla/b2g-emulator/gaia/xulrunner-sdk-30/xulrunner-sdk/bin/.

Ni?ing :ahal as per IRC conversation with :jmaher.

Update: Copying everything from the 'bin' directory caused problems with version mismatches between xpcshell and libxul.so. Copying _only_ the ssltunnel binary worked fine.

The correct fix here is to have the emulator builds also compile xpcshell. I've been looking into it, but this requires more work. See bug 1002545 for a workaround.
