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.
