Maybe rename pass -> result.  Otherwise the "pass = PIGLIT_FAIL" lines 
below read kind of weird.

The next test here should probably have a comment indicating what it's 
doing, like the others.  Actually, if it were me, I'd probably put each 
of these sub-tests into individual functions to more clearly delineate 
that each is independent of the other.

I don't think you need to allocate this memory at all.  You can pass 
NULL to glTexImage2D() and it'll still allocate the texture memory. 
Also, as-is, valgrind would probably flag a zillion uninitialized memory 
errors in glTexImage since you're not initializing the memory.

If the following tests were put in a separate function, I think you 
could pass the texture target as a parameter and easily check 
GL_TEXTURE_2D_ARRAY also.

You don't need two err_out sections.  Just delete both textures here. 
OpenGL won't complain if you try to delete an invalid texture ID.

I don't think you need to call piglit_report_result() here in 
piglit_display().  The return value should be enough.

Heck, you could probably replace all the "pass = PIGLIT_FAIL; goto 
err_out;" code with a simple "return PIGLIT_FAIL".  I don't think it's a 
big deal if we leak some texture objects when a test fails.
