Detailed Description

Unit test for geometry functionalities on a standard detector.

Date

June 22, 2017

Author

Gianluca Petrillo (petri.nosp@m.llo@.nosp@m.fnal..nosp@m.gov)

Usage:

geometry_loader_test  ConfigurationFile [test configuration FHiCL path]

The configuration file path must be complete, i.e. it must point directly to the configuration file. By default, the test configuration is expected in "physics.analysis.geotest".

This unit test uses StaticLoadGeometry() to set up the geometry.

Definition in file geometry_loader_test.cxx.

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 ("Geometry_test")

1. path to the FHiCL configuration file
2. FHiCL path to the configuration of the geometry test (default: physics.analysers.geotest)
3. FHiCL path to the configuration of the geometry (default: services.Geometry)
