 * \brief Test case hierarchy node
 *
 * Test node forms the backbone of the test case hierarchy. All objects
 * in the hierarchy are derived from this class.
 *
 * Each test node has a type and all except the root node have name and
 * description. Root and test group nodes have a list of children.
 *
 * During test execution TestExecutor iterates the hierarchy. Upon entering
 * the node (both groups and test cases) init() is called. When exiting the
 * node deinit() is called respectively.

 * \brief Test case class
 *
 * Test case implementations must inherit this class.
 *
 * Test case objects are usually constructed when TestExecutor enters parent
 * group. Allocating any non-parameter resources, especially target API objects
 * must be delayed to init().
 *
 * Upon entering the test case TestExecutor calls init(). If initialization
 * is successful (no exception is thrown) the executor will then call iterate()
 * until test case returns STOP. After that deinit() will be called.
 *
 * Before exiting the execution phase (i.e. at returning STOP from iterate())
 * the test case must set valid status code to test context (m_testCtx).
 *
 * Test case can also signal error condition by throwing an exception. In
 * that case the framework will set result code and details based on the
 * exception.
