Yes, I added a test for whether qcopy_file_preserving works on its own
(i.e. in a program that does not also call copy_file_preserving).
If you want to add tests for some of the specific return codes, please do
so, without changing the part that calls copy_file_preserving. Also please
don't write on file1. But you can construct different destination file names
based on file2.
Generally it's desirable to write tests in such a way that the different
parts of the tests operate on different destination files:
- If the test fails, the state on disk contains more info about what
failed.
- When adding new code to the test, you don't need to consider the
specific state of the destination file, reading through all the code
before. Just add a new destination file.
Using the same source file (file1) throughout the entire test is OK, though,
because it doesn't change.
