|
|
# This script compares two files for HDF5 testing. It supports both string and
|
|
# size-based comparisons, and can be used to check if files are equal, less than,
|
|
# greater than, etc., depending on the TEST_FUNCTION argument.
|
|
#
|
|
# Required variables:
|
|
# - TEST_FOLDER: Directory containing the files
|
|
# - TEST_ONEFILE: Name of the first file
|
|
# - TEST_TWOFILE: Name of the second file
|
|
# - TEST_FUNCTION: Comparison function (LT, LTEQ, EQ, GTEQ, GT)
|
|
# - TEST_STRINGS: If set to "YES", compare file contents as strings
|
|
# - TEST_EXPECT: Expected result code for string comparison
|
|
# - TEST_ERROR: Error message to display on failure
|
|
# -----------------------------------------------------------------------------
|
|
|
|
# Check that all required arguments are defined
