# Create a submodule layout used for all tests below.
#
# The following use cases are covered:
# - New submodule (no_submodule => add_sub1)
# - Removed submodule (add_sub1 => remove_sub1)
# - Updated submodule (add_sub1 => modify_sub1)
# - Submodule updated to invalid commit (add_sub1 => invalid_sub1)
# - Submodule updated from invalid commit (invalid_sub1 => valid_sub1)
# - Submodule replaced by tracked files in directory (add_sub1 =>
# replace_sub1_with_directory)
# - Directory containing tracked files replaced by submodule
# (replace_sub1_with_directory => replace_directory_with_sub1)
# - Submodule replaced by tracked file with the same name (add_sub1 =>
# replace_sub1_with_file)
# - Tracked file replaced by submodule (replace_sub1_with_file =>
# replace_file_with_sub1)
