Running on try
To run the IPC Reftests on try, add the following try: block to the end of the topmost commit message when you push to try.
try: -b do -u reftest-ipc
For more information, refer to the TryChooser documentation.
Running with build environment
First, setup a Firefox build environment. In the following examples, $(OBJDIR) is the build's object directory. This is prefixed with obj-, and the exact name depends on your system and OS.
Run all tests
$ MOZ_LAYERS_FORCE_SHMEM_SURFACES=1 make -C $(OBJDIR) reftest-ipc
Running with built packages
First, download and extract the built test packages. The following commands require the extracted tests path as the working directory.
$ python reftest/runreftest.py --appname=$(APPLICATION) --utility-path=bin --extra-profile-file=bin/plugins --setpref=browser.tabs.remote=true reftest/tests/layout/reftests/reftest-sanity/reftest.list
Substitute $(APPLICATION) with the relative or absolute path to the Firefox binary. For example on Windows this might be firefox/firefox.exe and on Mac OS FirefoxNightly.app/Contents/MacOS/firefox-bin.
Manifests
The final argument is the manifest file, which determines the tests to be run. If you don't want to use the {{ Source("layout/reftests/reftest-sanity/reftest.list", "default manifest") }}, simply change this argument to point to an alternative. The format of the manifest is covered in Writing Reftests.
