Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques like *'кукольный бег'*. The correct equivalent is 'пробный запуск', 'репетиция', 'генеральная репетиция' (for events), or 'тестовый прогон' (in tech).
Common Mistakes
- Using it as a verb (*'We dummy-ran the procedure'*) is non-standard. Use 'do/carry out a dummy run'. Confusing it with 'decoy run' or 'fake run', which imply intent to deceive rather than to practise.

In this fixed phrase, 'dummy' means 'simulated' or 'not real' (like a crash test dummy) and is not generally considered offensive. However, sensitivity around the word 'dummy' (meaning a stupid person) means some may prefer synonyms like 'trial run'.
