CTA Data Management & Result Logging 2 — Questions and Answers
Question 1: In TestStand, where is the result listener callback sequence typically located that processes results after a UUT test completes?
- In the station globals file
- In the process model sequence file (Correct answer)
- In the test sequence file itself
- In the TestStand engine configuration
Correct answer: In the process model sequence file
Result listener callback sequences, such as LogResults, are defined in the process model sequence file (e.g., SequentialModel.seq) and are called after UUT execution completes.
Question 2: Which TestStand API property allows a sequence to programmatically disable logging for specific steps without modifying the result listener?
- Step.Result.Status
- Step.RunOptions.RecordResults (Correct answer)
- Step.Properties.LoggingEnabled
- Execution.DisableResultLogging
Correct answer: Step.RunOptions.RecordResults
Step.RunOptions.RecordResults controls whether an individual step's results are recorded and passed to the result listener, allowing selective logging per step.
Question 3: What does TestStand use to uniquely identify a test socket across multiple executions in the database logging schema?
- Socket Index
- Station ID + Socket Index combined (Correct answer)
- Execution ID
- UUT Serial Number
Correct answer: Station ID + Socket Index combined
The combination of Station ID and Socket Index uniquely identifies a test socket, allowing the database to associate results with the correct physical socket on a multi-site tester.
Question 4: When configuring the XML result listener in TestStand, which XML schema standard can be used to define the structure of the output file?
- DTD (Document Type Definition) only
- TestStand proprietary XSD
- ATML XSD or TestStand XSD (Correct answer)
- JSON Schema
Correct answer: ATML XSD or TestStand XSD
The TestStand XML result listener supports output conforming to either the ATML XSD or the TestStand proprietary XSD schema, providing flexibility in output format.
Question 5: Which TestStand component is responsible for calling result listeners in the correct order when multiple result listeners are enabled?
- The Execution object
- The process model's LogResults callback (Correct answer)
- The Station Options dialog
- The TestStand Engine's result dispatcher
Correct answer: The process model's LogResults callback
The LogResults callback in the process model iterates through and calls each enabled result listener in sequence, making the process model the coordinator of result dispatching.
Question 6: In TestStand batch result logging, what is the purpose of the BATCH_RESULT_LIST table?
- To store the list of test steps in a batch sequence
- To aggregate multiple UUT results under a single batch execution record (Correct answer)
- To log batch operator credentials
- To store batch configuration file paths
Correct answer: To aggregate multiple UUT results under a single batch execution record
BATCH_RESULT_LIST is the parent table that groups multiple UUT_RESULT records under one batch execution, enabling batch-level reporting and traceability.
Question 7: Which TestStand step type is specifically designed to configure and control how test data is logged at the step level?
- Message Popup Step
- Property Loader Step
- Batch Synchronization Step
- Statement Step with RunOptions (Correct answer)
Correct answer: Statement Step with RunOptions
A Statement step combined with RunOptions configuration allows control of step-level logging behavior; the RunOptions on any step type govern whether results are recorded.
