CTA Data Management & Result Logging 3

Question 1

What is the recommended approach in TestStand to prevent the result listener from blocking the test execution thread when writing to a slow database?

Accepted Answer

Use asynchronous logging by offloading database writes to a worker thread

Answer

Asynchronous logging offloads database write operations to a separate worker thread so that the test execution thread is not blocked waiting for slow I/O operations to complete.

Question 2

In the TestStand database schema, which column in the STEP_RESULT table indicates whether a step passed or failed?

Accepted Answer

STATUS

Answer

The STATUS column in the STEP_RESULT table stores the pass/fail/error status string for each test step result logged to the database.

Question 3

When a TestStand sequence calls a subsequence, how are the subsequence's step results represented in the result list hierarchy?

Accepted Answer

Nested under the calling step's result as child results

Answer

Subsequence step results are nested as child results under the sequence call step in the parent's result list, preserving the hierarchical execution structure.

Question 4

Which TestStand feature allows administrators to configure how long test result data is retained in the database before automatic deletion?

Accepted Answer

Database Logger configuration with a data retention policy or purge stored procedure

Answer

Data retention and purging are typically managed through the Database Logger configuration and/or database-side stored procedures or jobs that remove records older than a configured threshold.

Question 5

What is the role of the 'Batch Serial Number' in TestStand result logging?

Accepted Answer

It provides a human-readable label for a group of UUTs tested in the same batch run

Answer

The Batch Serial Number is a user-assigned identifier that labels a group of UUT results belonging to the same batch execution, enabling traceability at the batch level.
