Your Mission

Seven questions, each a diagnosis. Speed bonus active.

Battle teaser

NoSuchElementException means:

  1. AThe element was found but is disabled
  2. BThe locator matched nothing in the current context at lookup time (wrong locator, wrong frame, or too early)
  3. CThe element exists but is invisible
  4. DThe session has expired
Answers, scoring, hints, and the full battle stay sealed.
