[webkit-help] Automatic Layout Test Execution for Cross Compiled Platforms

[Dirk Pranke]

Hi Arun,

Ryosuke's suggestion is a good one; in addition, I believe there is a
group at Sony (?) that has done something similar, but their patches
haven't been upstreamed yet.

It runs on the host.

Yes, things are compiled on the host. If you're developing
interactively, you just compile as normal, and then run
new-run-webkit-tests, which will either expect the binaries to have
been downloaded to the device, or download them itself. The script
contains all the hooks you need to implement whatever process you want
(it can even do a build to ensure things are up to date).

The major wrinkle you need to implement is to figure out some way for
the binary on the embedded driver to be able to access the test files
that live on the host. Usually either you can cross-mount a filesystem
or wrap file:// access urls in something like an http server that can
retrieve things.

In an automated system (like buildbot), the bot scripts run on the
host and just launch new-run-webkit-tests when appropriate.
