CTA Architecture & Framework 5

Question 1

In a CTA-level TestStand deployment, what is the recommended approach for distributing a custom process model to multiple test stations?

Accepted Answer

Package the process model in a TestStand deployment package and install on each station

Answer

TestStand deployment packages bundle all required files and register them correctly on each target station, ensuring consistent configuration across the fleet.

Question 2

What architectural decision determines whether a custom step type should store its properties in the step type definition versus in the step instance?

Accepted Answer

Properties that are the same for every instance belong in the type; instance-specific values belong in the step instance

Answer

Shared defaults and schema belong in the type definition, while values that vary per usage (like limit values or signal names) belong at the step instance level.

Question 3

How does TestStand's 'Expression' data type differ from a 'String' data type when used for step properties?

Accepted Answer

Expressions are evaluated at runtime against the current sequence context; strings are literal values

Answer

Expression properties are evaluated at runtime, allowing dynamic references to variables and calculations, while string properties are treated as static literal text.

Question 4

Which TestStand feature enables you to reuse the same sequence file across multiple products with different limit values without modifying the sequence?

Accepted Answer

Property Loader step with external limit files (CSV, XML, MDB)

Answer

The Property Loader step reads limits and properties from external files at runtime, enabling the same sequence to serve multiple product variants by swapping the limits file.

Question 5

In the TestStand execution model, what is the difference between 'Terminate' and 'Abort' when stopping an execution?

Accepted Answer

Terminate runs Cleanup steps before stopping; Abort stops immediately without Cleanup

Answer

Terminate gracefully stops the execution after running Cleanup step groups, while Abort halts immediately without executing Cleanup, potentially leaving resources unreleased.
