User can bind number of Unit Test classes (each having number of Test Cases) into a single Test Suite. When you run the test suite, it automatically runs the entire unit tests associated with this class. The following shows the syntax of a typical test suite class.
Important note: run_espec feature should be removed from the make routine of the unit test classes that you are adding to a test suite. E.g. UNIT_TEST_1 class should not call run_espec feature.
