Running Tests for WebKitGTK+

Dependencies

You will need to install the following Debian packages to run the layout tests. For other distributions, you must install the equivalent packages.

sudo apt-get install curl \
                     ruby \
                     apache2 \
                     libapache2-mod-php5 \
                     libapache2-mod-bw \
                     ttf-liberation \
                     otf-stix \
                     libgstreamer-plugins-base0.10-0 \
                     gstreamer0.10-plugins-base \
                     gstreamer0.10-plugins-good  \
                     gstreamer0.10-plugins-bad \
                     gstreamer0.10-ffmpeg \
                     xvfb

GStreamer -core and -plugins-base >= 0.10.30 is required.

Currently the tests require specific versions of some packages (this is for Debian):

apt-get install xfonts-100dpi=1:1.0.1 xfonts-75dpi=1:1.0.1  xfonts-base=1:1.0.1 xfonts-encodings=1:1.0.3-1 xfonts-scalable=1:1.0.1-1
apt-get install ttf-dejavu-core=2.31-1 ttf-dejavu-extra=2.31-1 ttf-lyx=1.6.7-1
apt-get install libfreetype6=2.4.2-2.1 libfreetype6-dev=2.4.2-2.1

Running the Tests

Simply run the run-webkit-tests script from the Tools directory. run-webkit-tests also supports the --debug argument to run the tests with the debug build of WebKitGTK+.

./Tools/Scripts/run-webkit-tests --gtk [--debug]

If you wish to run a single test you can do:

./Tools/Scripts/run-webkit-tests --gtk fast/forms/plaintext-mode-1.html

Pixel Tests

WebKitGTK+ supports running pixel tests, but they are not enabled by default. To run them simply pass the -p argument to run-webkit-tests:

./Tools/Scripts/run-webkit-tests --gtk -p

Adding Baselines

Sometimes you may need to generate new results for a test that relies on render tree output. This can be accomplished by passing the --new-test-results option. Note that new pixel results require the -p option as well:

./Tools/Scripts/run-webkit-tests --gtk fast/forms/plaintext-mode-1.html --new-test-results

Running Tests in GDB

For debugging a test it may be useful to run it directly in DumpRenderTree (with gdb):

WebKitBuild/Debug/Programs/DumpRenderTree -v LayoutTests/fast/forms/plaintext-mode-1.html
