Testcase (FB)¶

FUNCTION_BLOCK Testcase EXTENDS Testcase_Base IMPLEMENTS IBaseIecUnitTest

Base class for a simple test case.

To implement a testcase:

1. Extend your test from this function block

2. Add {attribute 'test'} to the FB, so that it is identified as a test

3. Optionally add any of the following attributes as desired

   • {attribute 'testcategory':='<add categories here>'}

   • {attribute 'testcasename':='<new name>'} to use a testcasename other then the FB name

   • {attribute 'testcasetimeout':='<timeout in ms>'} to alter the default timeout for this test

4. Add a call to SUPER^() to your implementation of the FB.

5. Overwrite method Execute() to implement your test

6. Optionally overwrite any of the following methods as desired

   • |Testcase_Base.Setup|

   • |Testcase_Base.Abort|

   • |Testcase_Base.Teardown|

InOut:

Scope	Name	Type	Comment	Inherited from
Input	xExecute	BOOL	Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError, iError) are present at the outputs for exactly one cycle.	ETrigA
	xAbort	BOOL	TRUE: Action is stopped immediately and all outputs are reset to their initial values.	ETrigA
Output	xDone	BOOL	TRUE: Action successfully completed	ETrigA
	xBusy	BOOL	TRUE: Function block active	ETrigA
	xError	BOOL	TRUE: Error occurred, function block aborts action FALSE: No error	ETrigA
	xAborted	BOOL	TRUE : Action aborted by user	ETrigA
	xFinished	BOOL		Testcase_Base
	sInfo	WSTRING(Constants.WSTRING_LENGTH)	additional information (e.g. an error text)
