  1. Which TestStand architecture component is responsible for routing test results to multiple output destinations simultaneously?

    Answer: Result Listener

    Result Listeners are plug-in components that receive test results and can route them to databases, reports, or custom destinations simultaneously.

  2. In a TestStand parallel model, what is the primary role of the TestSocket?

    Answer: It represents an independent thread of execution with its own UUT

    A TestSocket represents a single independent thread of execution associated with one Unit Under Test (UUT) in a parallel testing model.

  3. What is the correct way to make a type-safe call to a step type's custom properties in TestStand code modules?

    Answer: Access them directly via the Step object's PropertyObject

    Custom step properties are accessed via the Step's underlying PropertyObject using typed Get/Set methods to ensure type safety.

  4. When designing a custom process model, which callback sequence is invoked once per test session regardless of how many UUTs are tested?

    Answer: TestSocketSetup

    TestSocketSetup runs once per test socket when the test session begins, initializing resources shared across all UUT tests on that socket.

  5. Which TestStand feature allows you to share a single instrument driver instance across multiple parallel test sockets?

    Answer: Resource Locking with the Synchronization Step

    Resource Locking via Synchronization steps controls exclusive access to shared instruments across parallel sockets, preventing simultaneous conflicting access.

  6. In TestStand's sequence file architecture, what distinguishes a sequence file's 'Locals' from 'Parameters'?

    Answer: Parameters are passed from the caller; Locals are internal to the sequence

    Parameters are values passed into a sequence by its caller, while Locals are variables declared within the sequence and not visible to callers.

  7. Which architectural pattern does TestStand's process model use to allow customization without modifying the core engine?

    Answer: Template Method Pattern

    The Template Method Pattern defines the skeleton of the test flow in the process model, with specific callback sequences as extension points for customization.
