- tests.conftest.json_factory()
Json factory for getting json files
- tests.conftest.pytest_addoption(parser)
Pytest hook; implemented to add the –true-context option, used to indicate that a true Tango subsystem is available, so there is no need for a
tango.test_context.MultiDeviceTestContext
. :type parser: :param parser: the command line options parser :type parser:argparse.ArgumentParser

Setting mid Csp subarray leaf node and Sdp subarray leaf node availabilty attribute isSubsystemAvailable as True for aggregation
- tests.conftest.subarray_node(event_recorder, request)
Returns the instance of SubarrayNode class
- tests.conftest.tango_context(devices_to_load, request)
This Fixture provide the tango context fixture
- tests.conftest.task_callback()
Creates a mock callable for asynchronous testing
- Return type
MockCallable
common_utils module
Path: tests/test_helpers/
