     88  * in the hierarchy are derived from this class.

     91  * description. Root and test group nodes have a list of children.
     92  *
     93  * During test execution TestExecutor iterates the hierarchy. Upon entering
     94  * the node (both groups and test cases) init() is called. When exiting the
     95  * node deinit() is called respectively.

    152  * \brief Test case class
    153  *
    154  * Test case implementations must inherit this class.
    155  *
    156  * Test case objects are usually constructed when TestExecutor enters parent
    157  * group. Allocating any non-parameter resources, especially target API objects
    158  * must be delayed to init().
    159  *
    160  * Upon entering the test case TestExecutor calls init(). If initialization
    161  * is successful (no exception is thrown) the executor will then call iterate()
    162  * until test case returns STOP. After that deinit() will be called.
    163  *
    164  * Before exiting the execution phase (i.e. at returning STOP from iterate())
    165  * the test case must set valid status code to test context (m_testCtx).
    166  *
    167  * Test case can also signal error condition by throwing an exception. In
    168  * that case the framework will set result code and details based on the
    169  * exception.
