Hum, it is hard to know if that's any better to keep polluting the source tree with tests files, or polluting the stage directories...? Ideally we wouldn't need such files to run tests!
Do you know anything about these files?
I'm wondering why it still works as:
* all files crafted by the build system now lives in stage dir so tests won't have any of these files working,
* we are no longer shipping these html files in apps zip.
