What is Path-Dependent Input in Keyboard Access Testing?

• A. Input that can be captured via a single keystroke
• B. Input that requires the path of the user's input, such as drawing with a mouse, that would need an unreasonable amount of keyboard input to compare
• C. Any input that uses a mouse
• D. Input that is independent of user input

Answer: (B)

Path-Dependent Input means the result depends on the exact path or route the user takes to provide input, not just the final value. In keyboard access testing, some actions are driven by a mouse path or gesture. Trying to reproduce that same interaction with a keyboard would require a long, impractical sequence of keystrokes to trace the path, so a straightforward one-to-one comparison isn’t feasible. The idea is to recognize that certain interactions depend on the shape or route of input, not merely on a final outcome, and to test them in a way that accounts for that path. The example given—drawing with a mouse—illustrates this: reproducing the same path with keyboard input would be unwieldy, which is why it’s described as path-dependent.
