- __init__(profile_name)[source]#
Use an existing profile.
- Parameters
profile_name – Name of the profile to be loaded
- __module__ = 'aiida.manage.tests.main'#
- __weakref__#
list of weak references to the object (if defined)
- clear_profile()[source]#
Reset the global profile, clearing all its data and closing any open resources.
If the daemon is running, it will be stopped because it might be holding on to entities that will be cleared from the storage backend.
- class aiida.manage.tests.main.TemporaryProfileManager(backend='core.psql_dos', pgtest=None)[source]#
Bases:
aiida.manage.tests.main.ProfileManager
Manage the life cycle of a completely separated and temporary AiiDA environment.
No profile / database setup required
Tests run via the TemporaryProfileManager never pollute the user’s working environment
Filesystem:
temporary
.aiida
configuration foldertemporary repository folder
Database:
temporary database cluster (via the
pgtest
package)with
aiida
database userwith
aiida_db
database
AiiDA:
configured to use the temporary configuration
sets up a temporary profile for tests
All of this happens automatically when using the corresponding tests classes & tests runners (unittest) or fixtures (pytest).
Example:
tests = TemporaryProfileManager(backend=backend) tests.create_aiida_db() # set up only the database tests.create_profile() # set up a profile (creates the db too if necessary) # ready for tests # run tests 1 tests.clear_profile() # database ready for independent tests 2 # run tests 2 tests.destroy_all() # everything cleaned up
- __annotations__ = {}#
- __init__(backend='core.psql_dos', pgtest=None)[source]#
Construct a TemporaryProfileManager
- Parameters
backend – a database backend
pgtest – a dictionary of arguments to be passed to PGTest() for starting the postgresql cluster, e.g. {‘pg_ctl’: ‘/somepath/pg_ctl’}. Should usually not be necessary.

Collection of pytest
fixtures that are intended for use in plugin packages.
To use these fixtures, simply create a conftest.py
in the tests folder and add the following line:
pytest_plugins = [‘aiida.manage.tests.pytest_fixtures’]
This will make all the fixtures in this file available and ready for use. Simply use them as you would any other
pytest
fixture.

Return a loaded AiiDA test profile.
If a test profile has been declared, as returned by the
aiida_test_profile
fixture, that is loaded and yielded. Otherwise, a temporary and fully isolated AiiDA instance is created, complete with a loaded test profile, that are all automatically cleaned up at the end of the test session. The storage backend used for the profile isPsqlDosBackend
.
- aiida.manage.tests.pytest_fixtures.aiida_profile_clean(aiida_profile)[source]#
Provide an AiiDA test profile, with the storage reset at test function setup.
- aiida.manage.tests.pytest_fixtures.aiida_profile_clean_class(aiida_profile)[source]#
Provide an AiiDA test profile, with the storage reset at test class setup.

Create a temporary profile, add it to the config of the loaded AiiDA instance and load the profile.
The default configuration is complete except for the configuration of the storage, which should be provided through the
custom_configuration
argument. The storage will be fully reset and initalised, destroying all data that it contains and recreate the default user, making the profile ready for use.
- aiida.manage.tests.pytest_fixtures.aiida_test_profile() str | None [source]#
Return the name of the AiiDA test profile if defined.
The name is taken from the
AIIDA_TEST_PROFILE
environment variable.- Returns
The name of the profile to you for the test session or
None
if not defined.
- aiida.manage.tests.pytest_fixtures.clear_database(clear_database_after_test)[source]#
Alias for ‘clear_database_after_test’.
Clears the database after each test. Use of the explicit ‘clear_database_after_test’ is preferred.
- aiida.manage.tests.pytest_fixtures.clear_database_after_test(aiida_profile)[source]#
Clear the database after the test.
- aiida.manage.tests.pytest_fixtures.clear_database_before_test(aiida_profile)[source]#
Clear the database before the test.
- aiida.manage.tests.pytest_fixtures.clear_database_before_test_class(aiida_profile)[source]#
Clear the database before a test class.
- aiida.manage.tests.pytest_fixtures.clear_profile()[source]#
Clear the currently loaded profile.
This ensures that the contents of the profile are reset as well as the
Manager
, which may hold references to data that will be destroyed. The daemon will also be stopped if it was running.
- aiida.manage.tests.pytest_fixtures.config_psql_dos(tmp_path_factory: pytest.tmpdir.TempPathFactory, postgres_cluster: dict[str, str]) t.Callable[[dict[str, t.Any] | None], dict[str, t.Any]] [source]#
Return a profile configuration for the
PsqlDosBackend
.
- aiida.manage.tests.pytest_fixtures.daemon_client(aiida_profile)[source]#
Return a daemon client for the configured test profile for the test session.
The daemon will be automatically stopped at the end of the test session.
- aiida.manage.tests.pytest_fixtures.entry_points(monkeypatch) aiida.manage.tests.pytest_fixtures.EntryPointManager [source]#
Return an instance of the
EntryPointManager
which allows to temporarily add or remove entry points.This fixture creates a deep copy of the entry point cache returned by the
aiida.plugins.entry_point.eps()
method and then monkey patches that function to return the deepcopy. This ensures that the changes on the entry point cache performed during the test through the manager are undone at the end of the function scope.Note
This fixture does not use the
suppress_deprecations
decorator on purpose, but instead adds it manually inside the fixture’s body. The reason is that otherwise all deprecations would be suppressed for the entire scope of the fixture, including those raised by the code run in the test using the fixture, which is not desirable.
- aiida.manage.tests.pytest_fixtures.postgres_cluster(database_name: str | None = None, database_username: str | None = None, database_password: str | None = None) Generator[dict[str, str], None, None] [source]#

right
dictionary into theleft
dictionary.- Parameters

left
dictionary.
- aiida.manage.tests.pytest_fixtures.ssh_key(tmp_path_factory) Generator[pathlib.Path, None, None] [source]#
Generate a temporary SSH key pair for the test session and return the filepath of the private key.
The filepath of the public key is the same as the private key, but it adds the
.pub
file extension.
- aiida.manage.tests.pytest_fixtures.started_daemon_client(daemon_client)[source]#
Ensure that the daemon is running for the test profile and return the associated client.
- aiida.manage.tests.pytest_fixtures.stopped_daemon_client(daemon_client)[source]#
