eu07 --test -s <scenery> [--test-timeout <s>] runs the scenery in ghostview with
the null renderer (models loaded, no textures), a hidden window, no sound,
network or python, and in fixed steps of 0.03 s of simulation time per frame
(three 10 ms physics steps) as fast as it can. Without -seed it uses a fixed
seed, so two runs give byte-identical physicslogs.
The scenery reports its result to the __test.result memory cell, which the
simulator always creates: value 1 passes once every vehicle has stood still for
1 s, value 0 fails at once. The run ends with exit code
0 pass, 1 fail,
2 a train passed a signal at stop (SetVelocity 0 0, as seen in its driver's
speed table; SetVelocity 0 x on automatic block doesn't count),
3 timeout (test.timeout, default 3600 s of simulation time),
4 standstill (every vehicle still for test.standstill s, default 300, with no
result; a pass with test.pass_on_standstill yes),
5 error (no -s, the scenery didn't load or has no vehicles, an exception).
The test.* keys go in the scenery's config block; test.fail_if_stop_overran no
only logs a signal passed at danger. Outside the test mode a signal passed at
danger is logged.
The null renderer gets a ui backend which draws nothing, hands out the null
texture and material instead of throwing, and ends the ui frame. A GL context
is still made for the hidden window, without asking for a version, as parts
of the ui create textures with gl calls of their own. No crash dialog or
message box in test mode; the window code no longer needs a monitor.
Pressing Alt toggles picking mode. This is fine for keyboard and mouse usage,
but some use cases, such as disabling picking mode when a finger is placed
on a thumbstick and enabling it back when it's lifted, require finer control.
Allow to always enable picking mode when pressing Alt with Shift, and to always
disable picking mode when pressing Alt with Ctrl.
