3  * @brief Base class for tests using Boost unit test library
4  * @date May 22th, 2015
5  * @author petrillo@fnal.gov
6  * @see unit_test_base.h
7  *
8  * Provides an environment for easy set up of a Boost test.
9  * This is based and wraps the objects in unit_test_base.h.
10  * Since the wrapping is implemented by templates, derived classes than share
11  * interface with the unit_test_base.h objects should also work with the
12  * wrappers.
13  *
14  * For an example of usage, see larcore/test/Geometry/geometry_iterator_test.cxx
15  *
16  * This is a pure template header. It will require the same libraries as
17  * unit_test_base.h .

44  * It is supposed to be passed as a template parameter to another class

48  * This template just adds to the standard construction of the wrapped class
49  * a configuration that reads the parameters from the command line.
50  * It also hides all the constructors except two.
