Which of the following is not a step in using incremental development to create a prototype workspace?

• A. Save the workspace after testing a section, then test the next section.
• B. Test each section immediately after it is completed.
• C. Create a custom transformer to improve the testing process.
• D. Plan your project as a series of small sections, each of which would fit inside a bookmark in FME.

Answer: (C)

Incremental development for a prototype workspace focuses on breaking the project into small, testable parts and validating each part before moving on. Plan the project as a series of tiny sections that can be isolated, such as sections that fit inside a bookmark in FME. Build a section, test it, and then save the workspace before proceeding to the next, so progress is preserved and issues are caught early. Testing each section as soon as it’s completed helps ensure the prototype behaves as expected, with fixes applied step by step. Creating a custom transformer to improve the testing process isn’t a required step in this workflow; it’s an optional optimization or enhancement that goes beyond the basic iterative approach. The remaining steps—planning in small, bookmark-sized sections, testing after each completion, and saving after testing—align directly with building a prototype workspace incrementally.
