34 # This plain test program mimics the structure and contents of its
35 # ATF-based counterpart. It attempts to represent various test cases
36 # in different separate functions and just calls them all from main.
38 # In reality, plain test programs can be much simpler. All they have
39 # to do is return 0 on success and non-0 otherwise.
44 # Prints an error message and exits.
50 # Auxiliary function to compare two files for equality.

72 # If you have read the cp_test.sh counterpart in the atf/ directory, you
73 # may think that the sequencing of tests below and the exposed behavior
74 # to the user is very similar. But you'd be wrong.
76 # There are two major differences with this and the ATF version. The
77 # first is that the code below has no provisions to detect failures in
78 # one test and continue running the other tests: the first failure
79 # causes the whole test program to exit. The second is that this
80 # particular "main" has no arguments: without ATF, all test programs may
81 # expose a different command-line interface, and this is an issue for
82 # consistency purposes.
