// CLASS: uvm_test
//
// This class is the virtual base class for the user-defined tests.
//
// The uvm_test virtual class should be used as the base class for user-defined
// tests. Doing so provides the ability to select which test to execute using
// the UVM_TESTNAME command line or argument to the <uvm_root::run_test> task.
//
// For example
//
//| prompt> SIM_COMMAND +UVM_TESTNAME=test_bus_retry
//
// The global run_test() task should be specified inside an initial block
// such as
//
//| initial run_test();
//
// Multiple tests, identified by their type name, are compiled in and then
// selected for execution from the command line without need for recompilation.
// Random seed selection is also available on the command line.
//
// If +UVM_TESTNAME=test_name is specified, then an object of type 'test_name'
// is created by factory and phasing begins. Here, it is presumed that the
// test will instantiate the test environment, or the test environment will
// have already been instantiated before the call to run_test().
//
// If the specified test_name cannot be created by the <uvm_factory>, then a
// fatal error occurs. If run_test() is called without UVM_TESTNAME being
// specified, then all components constructed before the call to run_test will
// be cycled through their simulation phases.
//
// Deriving from uvm_test will allow you to distinguish tests from other
// component types that inherit from uvm_component directly. Such tests will
// automatically inherit features that may be added to uvm_test in the future.
//
//------------------------------------------------------------------------------
virtual class uvm_test extends uvm_component;
// Function: new
//
// Creates and initializes an instance of this class using the normal
// constructor arguments for <uvm_component>: ~name~ is the name of the
// instance, and ~parent~ is the handle to the hierarchical parent, if any.
