I am not very thrilled to see that it depends on . and .. to always exist, which may be true for all POSIX filesystems, but still... Agreed. I didn't find any one-liners to do that (ls -A isn't POSIX), so I decided to wrap that in a function. Testing that rmdir on the directory succeeds (because the directory is empty) would kinda work, but then we'd have to re-create the directory afterwards, which really doesn't sound like a good strategy either as the test would manipulate the to-be-tested object. I'm not terribly happy with depending on . and .. either, but couldn't come up with something better. At least the test should fail for any filesystem not having the dot files ... Do expected callsites of this helper care if $1 is a symbolic link that points at an empty directory? Yep, a symbolic link pointing to an empty directory should make the test fail. What do expected callsites really want to ensure? In other words, why do they care if the directory is empty? Is it to make sure, after some operation, they can rmdir the directory? To assert that a submodule is created but *not* populated. This is intended to catch any possible fallout from the recursive checkout later, in case that would kick in when it shouldn't. t/test-lib-functions.sh | 11 +++ 1 file changed, 11 insertions(+) diff --git a/t/test-lib-functions.sh b/t/test-lib-functions.sh index 158e10a..93d10cd 100644 --- a/t/test-lib-functions.sh +++ b/t/test-lib-functions.sh @@ -489,6 +489,17 @@ test_path_is_dir () { fi } +# Check if the directory exists and is empty as expected, barf otherwise. +test_dir_is_empty () { + test_path_is_dir $1 + if test $(ls -a1 $1 | wc -l) != 2 + then + echo Directory '$1' is not empty, it contains: + ls -la $1 + return 1 + fi +} + test_path_is_missing () { if [ -e $1 ] then Why not do something like test -z $(ls -a1 $1 | egrep -v '^\.\.?$') I.e., make the test ignore . and .. without depending on their existence?
