wrench
wrench
is a tool for debugging webrender outside of a browser engine.
Build
Build wrench
with cargo build --release
within the wrench
directory.
headless
wrench
has an optional headless mode for use in continuous integration. To run in headless mode, instead of using cargo run -- args
, use ./headless.py args
.
show
If you are working on gecko integration you can capture a frame via the following steps.
- Visit about:support and check that the "Compositing" value in the "Graphics" table says "WebRender". Enable
gfx.webrender.all
in about:config if necessary to enable WebRender. - Hit ctrl-shift-3 to capture the frame. The data will be put in
~/wr-capture
. - View the capture with
wrench show ~/wr-capture
.
reftest
Wrench also has a reftest system for catching regressions.
- To run all reftests, run
script/headless.py reftest
- To run specific reftests, run
script/headless.py reftest path/to/test/or/dir
- To examine test failures, use the reftest analyzer
- To add a new reftest, create an example frame and a reference frame in
reftests/
and then add an entry toreftests/reftest.list
