We've been primarily running and testing with DumpRenderTree (in Tools/DumpRenderTree), as this is what the WebKit layout tests use. DumpRenderTree -p will give you an image rendering of the webpage. However, it shouldn't be difficult to get QtTestBrowser to run assuming it doesn't require a display. I can look into this tomorrow.

Thanks. I've tried using DumpRenderTree however i'm receiving a similar error:
root@qemu-cheri128-sean:/mnt/build/qtwebkit-128-build/bin # ./DumpRenderTree -p /mnt/jsc/test.html
DumpRenderTree: _rtld_thread_init is not available when statically linked.
This application failed to start because it could not find or load the Qt platform plugin "bsdfb"
in "".
Available platform plugins are: offscreen, offscreen.
Reinstalling the application may fix this problem.
Abort
this is using the same build information as above.

hmm that is strange, it should use the offscreen plugin by default. Please try passing -platform offscreen.

Please could you also paste the contents of test.html? I'll try and reproduce this crash

Also, we currently have a Clang/LLVM -O2 optimisation bug and CTSRD-CHERI/qtwebkit@2e01c3e contains a workaround to avoid this, so might be worth updating to at least this.

Ah I've also noticed you don't have our sqlite alignment fix CTSRD-CHERI/sqlite@02b0fa5 . Updating sqlite should eliminate that alignment error you are seeing.

Thanks, I'm currently recompiling.

Looks like $c19 is only aligned to 8 bytes. I would have expected the last commit in SQlite to have fixed that. Is this also happening when running webkit?

Running DumpRenderTree with the following arguments appears to run, dumping the image output, albeit incredibly slow. (30 minutes per execution). Then proceeds to fault.

DumpRenderTree will be extremly slow if you don't have the mime.cache file on your system (it spends lots of time parsing a massive XML file that it doesn't actually use. If the mime.cache file is found it can just mmap() a pre-generated cache).
See https://github.com/CTSRD-CHERI/cheribuild/blob/master/test-scripts/run_qtwebkit_tests.py#L54 for how the test script sets up the environment and cheribuild.py qtwebkit should generate it in the build directory: https://github.com/CTSRD-CHERI/cheribuild/blob/master/pycheribuild/projects/cross/qt5.py#L404
I have also seen it crash if the fonts directory /usr/local/Qt-cheri/lib/fonts does not contain at least one .ttf file (the test script just copies the AHEM font and DroidSansFallback-reduced.ttf.
Does cheribuild.py qtwebkit --test --test-extra-args="--smoketest" --interact-after-tests work for you? (Note that you need to build the disk-image-minimal and cheribsd-mfs-root-kernel target first).

Running the qtwebkit smoketest now runs DumpRenderTree significantly faster and produces the output to the directed file when using the --stdout flag. This does perform as expected, however still crashes at the end with the following stack trace. The crash doesn't appear to affect the outcome of the test, and it appears to produce the correct output (looking at the dom tree).
