##### Generic fixture model

The UTF defines the generic fixture model as follows:

    struct <fixture-name>{
       <fixture-name>(); // setup function
       ~<fixture-name>(); // teardown function
    };

In other words a fixture is expected to be implemented as a class where the class constructor serves as a setup method and class destructor serves as teardown method. The UTF opted to avoid explicit names in fixture interface for setup and teardown methods, since is considered most natural in C++ for tasks similar to RAII and coincides with the pure C++ solution discusses earlier.

| Important
The above interface prevents you to report errors in the teardown procedure using an exception. It does make sense though: if somehow more than one fixture is assigned to a test unit, you want all teardown procedures to run, even if some may experience problems.
