aiida.backends.tests.utils package

Submodules

Module that defines methods to mock an AiiDA instance complete with mock configuration and profile.

aiida.backends.tests.utils.configuration.create_mock_profile(name, repository_dirpath=None)

Create mock profile for testing purposes.

Parameters:

• name – name of the profile
• repository_dirpath – optional absolute path to use as the base for the repository path

aiida.backends.tests.utils.configuration.temporary_config_instance(*args, **kwds)

Create a temporary AiiDA instance.

aiida.backends.tests.utils.configuration.temporary_directory(*args, **kwds)

Create a temporary directory.

aiida.backends.tests.utils.configuration.with_temp_dir(function)

Create a temporary directory for the duration of the wrapped function.

The path of the temporary directory is passed to the wrapped function via the ‘temp_dir’ parameter (which it must accept).

aiida.backends.tests.utils.configuration.with_temporary_config_instance(function)

Create a temporary AiiDA instance for the duration of the wrapped function.

Test utility to import fixtures, such as export archives.

aiida.backends.tests.utils.fixtures.import_archive_fixture(filepath)

Import a test fixture that is an AiiDA export archive

Parameters:filepath – the relative path of the archive file within the fixture directory
