Test Arguments¶

Name	Type	Description
bft_fixture	dict	A dictionary with the following items: `class_name` Fully-qualified class name of the BFTFixture implementation to use. `params` A dictionary of parameters for the BFTFixture class’s `Init()` method. The default value of `None` means that no BFT fixture is used.
criteria	dict	Criteria of measured voltage. A dict {ina_name: (schematic_name, expected_voltage, relative_tolerance)} where the unit of voltage is mV
timeout_secs	int, float	(optional; default: `10`) Total #seconds to perform voltage checking
poll_interval_secs	int, float	(optional; default: `0.3`) Pause between voltage check
