Isolated Ptc
^^^^^
**Definition:**

* A PTC is created and started, but neither connected to another component nor mapped to the TSI. A PTC which is not connected or mapped is isolated from all other components, especially the MTC, and is of no use for the test.


**Code Example:**

.. code-block:: pseudo

  testcase exampleTestCase() runs on MainComponentType system SystemType {
    // . . .
    var ParallelComponentType exampleComponent := ParallelComponentType.create;
    // no map or connect statement shere!
    exampleComponent.start(exampleBehavior())
    exampleComponent.done
    // . . .
  }
