CTA Sequence Development & Customization 1 — Questions and Answers
Question 1: What is the purpose of a main sequence in TestStand?
- To format reports
- To monitor keyboard input
- To execute primary test logic (Correct answer)
- To store temporary logs
Correct answer: To execute primary test logic
The main sequence defines the core logic of the test and typically includes setup, test steps, and cleanup.
Question 2: Which TestStand feature allows reuse of common test logic?
- Temporary variables
- Reusable subsequences (Correct answer)
- UI controls
- Single-pass sequences
Correct answer: Reusable subsequences
Reusable code modules and subsequences reduce duplication and enhance maintainability.
Question 3: What does a custom step type allow?
- Hardcoded routines
- New process models
- Reusable, tailored test operations (Correct answer)
- Manual test reports
Correct answer: Reusable, tailored test operations
Custom step types encapsulate functionality with predefined behavior, making sequences more consistent and easier to manage.
Question 4: Why is parameter passing important in TestStand sequences?
- To hide variable names
- To encrypt data
- To share data between steps (Correct answer)
- To simplify cleanup
Correct answer: To share data between steps
Parameter passing allows sequences to communicate and operate dynamically based on input/output values.
Question 5: Which setting defines what a step does on failure?
- Run Mode
- Step Properties
- Post Action (Correct answer)
- Execution Entry Point
Correct answer: Post Action
The Post Action setting defines the behavior after a step finishes, including on failure (e.g., terminate, go to cleanup).
Question 6: How can TestStand developers debug sequences efficiently?
- By disabling logs
- Using the report viewer only
- By using breakpoints and watches (Correct answer)
- Through the command prompt
Correct answer: By using breakpoints and watches
Using breakpoints, watch expressions, and the execution view enables step-by-step debugging and monitoring of variables.
