The following table lists the Engine callbacks TestStand defines, indicates where you must define the callback, and specifies when the engine calls the callback.

Engine Callback	Where You Define the Callback	When the Engine Calls the Callback
SequenceFilePreStep	Any sequence file	Before the TestStand Engine executes each step in the sequence file.
SequenceFilePostStep	Any sequence file	After the engine executes each step in the sequence file. The engine does not call this callback when a step errors.
SequenceFilePreInteractive	Any sequence file	Before the engine begins an interactive execution of steps in the sequence file.
SequenceFilePostInteractive	Any sequence file	After the engine completes an interactive execution of steps in the sequence file.
SequenceFileLoad	Any sequence file	When the engine loads the sequence file into memory.
SequenceFileUnload	Any sequence file	When the engine unloads the sequence file from memory.
SequenceFilePostResultListEntry	Any sequence file	After the engine fills out the step result for a step in the sequence file.
SequenceFilePostResults	Any sequence file	After the engine collects a step result in the sequence file and the number of collected results or the time since collected results were last processed exceeds a threshold.
SequenceFilePostStepRuntimeError	Any sequence file	After a step in the sequence file generates a run-time error.
SequenceFilePostStepFailure	Any sequence file	After a step in the sequence fails.
ProcessModelPreStep	Process model file	Before the engine executes each step in any client sequence file the process model calls and each step in any resulting subsequence calls.
ProcessModelPostStep	Process model file	After the engine executes each step in any client sequence file the process model calls and each step in any resulting subsequence calls. The engine does not call this callback when a step errors.
ProcessModelPreInteractive	Process model file	Before the engine begins an interactive execution of steps in a client sequence file and steps in any resulting subsequence calls.
ProcessModelPostInteractive	Process model file	After the engine completes an interactive execution of steps in a client sequence file and steps in any resulting subsequence calls.
ProcessModelPostResultListEntry	Process model file	After the engine fills out the step result for a step in any client sequence file the process model calls or in any resulting subsequence calls.
ProcessModelPostResults	Process model file	After the engine collects a step result for a step in any client sequence file the process model calls or in any resulting subsequence calls and the number of collected results or the time since collected results were last processed exceeds a threshold.
ProcessModelPostStepRuntimeError	Process model file	After a step generates a run-time error when the step is in a client sequence file the process model calls or in any resulting subsequence calls.
ProcessModelPostStepFailure	Process model file	After a step fails when the step is in a client sequence file the process model calls or in any resulting subsequence calls.
StationPreStep	StationCallbacks.seq	Before the engine executes each step in any sequence file.
StationPostStep	StationCallbacks.seq	After the engine executes each step in any sequence file. The engine does not call this callback when a step errors.
StationPreInteractive	StationCallbacks.seq	Before the engine begins any interactive execution.
StationPostInteractive	StationCallbacks.seq	After the engine completes any interactive execution.
StationPostResultListEntry	StationCallbacks.seq	After the engine fills out the step result for a step in any sequence file.
StationPostResults	StationCallbacks.seq	After the engine collects a step result for a step in any sequence file and the number of collected results or the time since collected results were last processed exceeds a threshold.
StationPostStepRuntimeError	StationCallbacks.seq	After any step generates a run-time error.
StationPostStepFailure	StationCallbacks.seq	After any step fails.

Note The threshold is in terms of the number of results the current thread has accumulated and the amount of time since the current thread last called its PostResults callbacks. For more information about the conditions that trigger PostResults callbacks, refer to Execution.PostResultsCallbackOptions, Execution.PostResultsCallbackInterval, Execution.MaximumResultsPerPostResultsCallback, and Thread.FlushPostResults.
