What this video covers
Two ways to spot usability problems. Usability testing watches real people trying tasks to see what actually trips them up. Heuristic evaluation has experts review the interface against known principles. One shows what happens in reality; the other predicts it - and they uncover strikingly different issues.
Run the experts and they flagged the contrast and consistency issues fast - but sailed past the wrong word and the missed button that only real users hit. Run the test and you caught those, but not the principle violations the experts spotted in minutes. Neither method saw everything; together they did. That's the whole case for using both.
