# Given a spec for the input file(s) or expected output file of a single
|
|
# test, create a file for any string. A file is created for each literal
|
|
# string -- not for named files. Whether a perl `string' is treated as
|
|
# a string to be put in a file for a test or the name of an existing file
|
|
# depends on how many references have to be traversed to get from
|
|
# the top level variable to the actual string literal.
|
|
# If $SPEC is a literal Perl string (not a reference), then treat $SPEC
|
|
# as the contents of a file.
|
|
# If $SPEC is a hash reference, then there are no inputs.
|
|
# If $SPEC is an array reference, consider each element of the array.
|
|
# If the element is a string reference, treat the string as the name of
|
|
# an existing file. Otherwise, the element must be a string and is treated
|
|
# just like a scalar $SPEC. When a file is created, its name is derived
|
|
# from the name TEST_NAME of the corresponding test and the TYPE of file.
|
|
# E.g., the inputs for test `3a' would be named t3a.in1 and t3a.in2, and
|
|
# the expected output for test `7c' would be named t7c.exp.
|
|
#
|
|
# Also, return two lists of file names:
|
|
# - maintainer-generated files -- names of files created by this function
|
|
# - files named explicitly in Test.pm
