test_description='git conflicts when checking files out test.'
# The first test registers the following filesystem structure in the
# cache:
#
# path0 - a file
# path1/file1 - a file in a directory
#
# And then tries to checkout in a work tree that has the following:
#
# path0/file0 - a file in a directory
# path1 - a file
#
# The git checkout-index command should fail when attempting to checkout
# path0, finding it is occupied by a directory, and path1/file1, finding
# path1 is occupied by a non-directory. With "-f" flag, it should remove
# the conflicting paths and succeed.

# The second test registers the following filesystem structure in the cache:

# Checkout cache should fail to extract path3/file1 because the leading
# path path3 is occupied by a non-directory. With "-f" it should remove
# the symlink path3 and create directory path3 and file path3/file1.
