using TestEnvironment = testing::TesterEnvironment<testing::BasicEnvironmentConfiguration>

Function Documentation

int main	(	int	argc,
		char const **	argv
	)

Runs the test.

Parameters

argc	number of arguments in argv
argv	arguments to the function

Returns

number of detected errors (0 on success)

Exceptions

cet::exception

most of error situations throw

The arguments in argv are: 0. name of the executable ("LArPropertiesStandard_test")

1. (mandatory) path to the FHiCL configuration file
2. FHiCL path to the configuration of the test (default: physics.analyzers.larptest)
3. FHiCL path to the configuration of LArProperties service (default: services.LArPropertiesService)
