Crate xvc_test_helper 

Helper functions to create random temporary directories, random binary or text files, and set logging in unit/integration tests. The directories may be initialized as Git or Xvc repositories.

Functions

create_directory_tree

Build a directory tree containing n_dirs under root. Each of these directories contain n_files_per_dir random binary files.

create_temp_dir

Create a random named temp directory under $TMPDIR

generate_filled_file

Creates a file filled with byte

generate_random_file

Generate a random binary file

generate_random_text_file

Generate a random text file composed of alphanumerics

make_symlink

Creates a symlink from target to original

random_dir_name

Generates a random name with prefix and a random number generated from seed. If seed is None, a random number from_entropy is used.

random_temp_dir

Return name of a random directory under $TMPDIR. It doesn’t create the directory, just returns the path.

run_in_temp_dir

Create a temporary dir under $TMPDIR and cd to it

run_in_temp_git_dir

Create an empty temporary Git repository without XVC_DIR

seeded_temp_dir

Return a temp directory created with a seed. If seed is None, it creates a random directory name. This function doesn’t create the directory.

temp_git_dir

Create a random directory and run git init in it.

test_logging

Turn on logging for testing purposes. Testing always send traces to $TMPDIR/xvc.log. The level here determines whether these are sent to stdout.
