Read the first 7 Sequence Development & Customization flashcards as text

  1. A CTA is designing a sequence that must support both interactive operator runs and automated batch runs. Which TestStand mechanism best handles UI-dependent steps conditionally?

    Answer: Use the Execution.Interactive property to conditionally show UI prompts

    Checking RunState.Execution.Interactive at runtime allows sequences to conditionally display UI elements only during interactive runs.

  2. When should a TestStand developer use the 'Goto' step instead of a loop construct?

    Answer: When implementing a state machine with non-linear flow

    Goto steps are appropriate for implementing state machines or exceptional flow transfers that loop constructs cannot elegantly express.

  3. What is the effect of enabling 'Ignore Run-time Errors' on a TestStand step?

    Answer: Errors from the code module do not propagate and the sequence continues

    With 'Ignore Run-time Errors' enabled, the step catches any error thrown by its code module and continues sequence execution without propagating the error.

  4. In TestStand sequence development, what is a 'Callback' step type primarily used for?

    Answer: Calling a user-defined sequence that overrides default process model behavior

    Callback steps invoke named sequences that override specific process model hooks, allowing site or project-level customization of standard behavior.

  5. Which TestStand data type should be used when a sequence needs to store a collection of UUT serial numbers of unknown size at design time?

    Answer: Array of String with dynamic resizing

    TestStand arrays support dynamic resizing at runtime using the Resize Array expression, making them ideal for collections of unknown size.

  6. A sequence uses a 'For Loop' step to iterate 100 times, but a mid-loop condition requires an early exit. Which step type achieves this cleanly?

    Answer: Break step inside the loop body

    The Break step exits the innermost active loop immediately, providing a clean structured early-exit mechanism.

  7. What is the recommended way to share configuration data (such as hardware addresses) across multiple sequence files in the same test system?

    Answer: Store them in StationGlobals and load at system startup

    StationGlobals persist for the entire station session and are the standard location for system-wide configuration data accessible by all sequences.
