Re: [pygame] Tests crashing Automatic Build page + Compiling PyGame on Windows

[Lenard Lindstrom <len-l@xxxxxxxxx>]

When I run the tests in the same, alphabetical, order as the automated 
build page I get :

ERROR: test_surfarray_ref (surflock_test.SurfaceLockTest)
----------------------------------------------------------------------
Traceback (most recent call last):
 File "test\surflock_test.py", line 141, in test_surfarray_ref
   ar = pygame.surfarray.pixels2d (sf)
 File "C:\PRG\PYTHON25\lib\site-packages\pygame\surfarray.py", line 
122, in pix
els2d
   return numericsf.pixels2d (surface)
ValueError: unsupport bit depth for 2D reference array


So the tests are interacting with each other in unintended ways. In my 
case to set_mode in a previous unit test left the default surface bit 
depth at 24, the same as my display. Without a call to set_mode the 
default is 32. This also explains the errors with transform_test.py and 
a 16 bit display. The freezing of the unit tests remains a mystery.
