# 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 =>
