What happens to a TestStand sequence's Locals when the sequence is called recursively?
Answer: Each recursive call gets its own separate Locals instance on the call stack
Each call to a sequence creates a new execution context with its own Locals instance, enabling safe recursion without variable conflicts.
In the TestStand batch model, what is the purpose of the 'Join' step in the MainSequence?
Answer: It synchronizes all parallel sockets at a common point before continuing
The Join step acts as a synchronization barrier, pausing execution until all parallel sockets reach the Join point before any proceed.
Which TestStand component is responsible for maintaining the list of loaded sequence files and managing their lifetimes?
Answer: Engine
The TestStand Engine object manages all loaded sequence files, active executions, and the overall runtime environment.
When a TestStand step's 'Run Mode' is set to 'Skip', what effect does this have on the step's result in the report?
Answer: The step appears in the report with a Skipped status
Skipped steps are still recorded in the report with a Skipped status, preserving traceability while excluding execution.
What is the primary advantage of using TestStand's 'Subsequence' step type over a 'Code Module' step for complex test logic?
Answer: Subsequences allow nesting of TestStand flow control within reusable units
Subsequences encapsulate TestStand-native flow control, loops, and error handling within a reusable callable unit, unlike code modules which execute external code linearly.
In TestStand, what is the scope of 'File Globals' relative to other variable scopes?
Answer: Accessible by all sequences within the same sequence file
File Globals are scoped to the sequence file in which they are declared, accessible by any sequence within that file but not by other files.
Which TestStand architecture feature enables a sequence to be edited and reloaded while an execution using it is still running?
Answer: Edit While Running
TestStand's Edit While Running feature allows modifying sequence files in the editor without terminating active executions, which pick up changes on their next pass.
