|
* Test Synopsis:
|
|
* - that unique thread sequence numbers are generated.
|
|
* - Analyse thread struct reuse.
|
|
*
|
|
* Test Method (Validation or Falsification):
|
|
* -
|
|
*
|
|
* Requirements Tested:
|
|
* -
|
|
*
|
|
* Features Tested:
|
|
* -
|
|
*
|
|
* Cases Tested:
|
|
* -
|
|
*
|
|
* Description:
|
|
* -
|
|
*
|
|
* Environment:
|
|
* - This test is implementation specific
|
|
* because it uses knowledge of internals that should be
|
|
* opaque to an application.
|
|
*
|
|
* Input:
|
|
* - None.
|
|
*
|
|
* Output:
|
|
* - File name, Line number, and failed expression on failure.
|
|
* - analysis output on success.
|
|
*
|
|
* Assumptions:
|
|
* -
|
|
*
|
|
* Pass Criteria:
|
|
* - unique sequence numbers are generated for every new thread.
