I would create a setup object and refer to it.

with Executable('ex62.c'):
  quadrature = dict()
  for dim in 1 2 3:
    for order in 1 2 3 4:
      quadrature[(dim,order)] = GeneratedFile('ex62.h',
command=[os.path.join(petsc_dir,'bin','pythonscripts','PetscGenerateFEMQuadrature.py'),
...])
  Test(..., requires=quadrature(2,3))
  # ... more tests, sharing one or more generated files

Each test, or group of tests, will normally be run in its own private
temporary directory. A sequence of tests sharing the same dependencies can
reuse the generated file, but if you test with -j48, members of the same
group may be executing concurrently.
