Sets up an appropriate environment and tests FEATUREs (all by default). Note
that this script must be run from the Tails source directory root.
Options for '@product' features:
--capture FILE Captures the test session into FILE using VP8 encoding.
Requires ffmpeg and libvpx1.
--debug Display various debugging information while running the
test suite.
--pause-on-fail On failure, pause test suite until pressing Enter. This is
useful for investigating the state of the VM guest to see
exactly why a test failed.
--keep-snapshots Don't ever delete the background snapshots. This can a big
time saver when debugging new features.
--retry-find Print a warning whenever Sikuli fails to find an image
and allow *one* retry after pressing ENTER. This is useful
for updating outdated images.
--temp-dir Directory where various temporary files are written
during a test, e.g. VM snapshots and memory dumps,
failure screenshots, pcap files and disk images
(default is /tmp/TailsToaster).
--view Shows the test session in a windows. Requires x11vnc
and xtightvncviewer.
--vnc-server-only Starts a VNC server for the test session. Requires x11vnc.
--iso IMAGE Test '@product' features using IMAGE. If none is given,
the ISO with most recent creation date (according to the
ISO's label) in the current directory will be used.
--old-iso IMAGE For some '@product' features (e.g. usb_install) we need
an older version of Tails, which this options sets to
IMAGE. If none is given, the ISO with the least recent
creation date will be used.
Note that '@source' features has no relevant options.
