Expert writing Tips

Best practice

Use "could have tested" to indicate a missed opportunity or a hypothetical situation where testing was possible but did not occur. Ensure the context clearly suggests the unrealized potential or past possibility.

Common error

Avoid using "could have tested" when you mean to say something was actually tested. "Could have tested" implies it didn't happen. Use "tested" (past simple) or "has been tested" (present perfect) for actual completed actions.
