The answer
Potentially. Each test transaction creates outputs and consumes transaction fees; in some cases it adds an extra UTXO that later costs money to spend.
What to do next
For significant transfers, the verification benefit can outweigh the small cost. Use a sensible test amount and confirm addresses in full before the main payment.
