Getting the Tests

Edit your mozconfig to contain the following lines:

ac_add_options --enable-tests

Get the source and build according to instructions.

Porting tests to N800

With changes from bug 421611 we have made this process much simpler.

If following directions for running fennec on N800/N810 devices, you will need to package up the tests from the xulrunner directory and the test harness from the source tree:

cd $(xul_objdir)
make package-tests
cd dist
bunzip2 xulrunner-*tests.tar.bz2
scp xulrunner-*tests.tar root@<deviceip>:/media/mmc1

On the device, untar the xulrunner-*tests.tar in your test directory alongside the fennec-*.tar:

cd /media/mmc1
mkdir unittests
mv fennec-*.tar unittests
mv xulrunner-*tests.tar unittests
cd unittests
tar -xvf fennec-*.tar
tar -xvf xulrunner-*tests.tar

Running Chrome tests on Fennec

Chrome tests are run just like mochitests except they have the --chrome flag set on the command line when launching.

python /media/mmc1/unittests/mochitest/ --autorun --close-when-done --chrome --utility-path=/media/mmc1/unittests/bin --appname=/media/mmc1/unittests/fennec/fennec --xre-path=/media/mmc1/unittests/fennec/xulrunner --certificate-path=/media/mmc1/unittests/certs --log-file=logs/log_content.txt

The Chrome tests will fail when run on a device. This is because we don't have enough memory available to load the whole set of tests into memory and execute.

To work around this, we run a subset of tests at a time. We have found that running one subdirectory under the chrome/ folder works out well. Once we have a --test-path that works for directories in chrome, we can do this easier. At the moment, we remove all files from the chrome/ directory and move the files over one directory at a time:

cd /media/mmc1/unittests/mochitest
cp -R chrome chrome.bak

## NOTE: you need to do the following steps in a look for each directory
## dirs: [content, docshell, dom, toolkit, widget]
rm -Rf chrome/*
cp -R chrome.bak/content chrome/

We have created a framework to wrap the unittests maemkit which makes this a little bit easier. Keeping the above example, you need to copy the maemkit files to /media/mmc1/maemkit.

Now Edit the /media/mmc1/maemkit/maemkit.cfg file:

xre-path = /media/mmc1/unittests/fennec/xulrunner
appname = /media/mmc1/unittests/fennec/fennec
total-clients = 1
client-number = 1
logdir = logs
ostype = linux

autorun = True
close-when-done = True
utility-path = /media/mmc1/unittests/bin
certificate-path = /media/mmc1/unittests/certs
backupdir = chrome.bak
testroot = /media/mmc1/unittests/mochitest
log-file = log_chrome.txt

Now execute the tests:

cd /media/mmc1/maemkit
python --testtype=chrome

You can view the results in /media/mmc1/maemkit/log_chrome.txt


  • HACK: in order to work around bugs bug 472334 and bug 472341, we need to turn on sessionhistory by setting a user_pref("browser.sessionhistory.max_total_viewers", -1) in
  • HACK: in order to get a [session store test] running, we need to set in and change domstorage_global.js#88 from 32767 to 8191 in the for loop
