Program Design and Development Practice Test

They first build and test a working text editor, then add file saving functionality, then add spell checking, ensuring each component works before starting the next.

They repeatedly build and test the entire application from scratch, making small refinements to the user interface in each cycle based on continuous user feedback.

They conduct extensive market research and user surveys for an extended period, creating a complete specification before writing any program code.

They first gather all possible user requirements, then complete the full application design, then write all the code, and finally test the entire application at the end.
