CTA CTA Test Management & Reporting 2 — Questions and Answers
Question 1: In TestStand's report generation pipeline, what is the purpose of the 'ResultProcessing' sequence?
- It compiles LabVIEW code before reporting
- It transforms raw result data into formatted report content (Correct answer)
- It uploads reports to a remote server
- It validates licenses before printing
Correct answer: It transforms raw result data into formatted report content
ResultProcessing sequences transform the raw result record hierarchy into the structured content consumed by report plugins.
Question 2: A station generates 500 UUT results per shift. Which result storage strategy minimizes database write contention in TestStand?
- Synchronous ADO commit per step
- Batch insert with transaction rollup per UUT (Correct answer)
- File-per-step CSV writes
- Single text file append
Correct answer: Batch insert with transaction rollup per UUT
Batching all step results into a single database transaction per UUT dramatically reduces lock contention and improves throughput.
Question 3: Which TestStand feature enables an architect to attach custom properties to every step result without modifying the core sequence file?
- Custom step types with additional data (Correct answer)
- Station globals
- Sequence file properties
- Process model result callbacks
Correct answer: Custom step types with additional data
Custom step types can define additional data fields that are automatically propagated to the result record for every instance of that step type.
Question 4: What is the role of the 'LogToDatabase' callback in a TestStand process model?
- It validates DB credentials at startup
- It is called after each UUT completes to persist results (Correct answer)
- It configures the ODBC driver
- It locks the station during writes
Correct answer: It is called after each UUT completes to persist results
The LogToDatabase callback fires after UUT completion, giving the process model a structured hook to persist result data to a back-end database.
Question 5: A CTA architect must ensure test reports are signed to prevent tampering. Which TestStand mechanism supports this?
- File-level CRC stored in station globals
- Digital signature via result plugin post-processing (Correct answer)
- Password-protecting the sequence file
- Encrypting the .seq file
Correct answer: Digital signature via result plugin post-processing
A custom result plugin can apply a cryptographic digital signature to the final report file after all result data has been written.
Question 6: In TestStand, which object model path gives programmatic access to a specific step's numeric measurement result?
- RunState.Execution.Result.Numeric
- Step.Result.Numeric (Correct answer)
- TS.StepResult.NumericMeasurement
- Locals.Measurement
Correct answer: Step.Result.Numeric
Step.Result.Numeric is the standard property path to read or write a step's numeric measurement within TestStand expressions.
