Contract

• assert load_dotenv returns False on missing, empty, or comments-only files
• assert load_dotenv returns True when valid keys exist even under override=False with pre-existing os.environ
• assert valueless keys parse as None in dotenv_values and are omitted from os.environ by load_dotenv
• assert dotenv_values does not mutate os.environ and prioritizes file definitions during interpolation
• assert load_dotenv with override=False resolves interpolated variables from os.environ over file values
• assert load_dotenv with override=True updates os.environ and uses overridden values during interpolation
• assert find_dotenv returns an empty string when the file is not found
• assert set_key returns a 3-tuple of success bool, key name, and set value
