Cultural Tip
In French workplaces, the informal imperative ‘Fais…’ is acceptable among peers, but in more formal settings you would use the polite plural ‘Faites…’. Also, French tech teams often stress ‘tests multiplateformes’ (cross‑platform testing) as a best practice, so pairing this phrase with a brief explanation of the devices you plan to test can sound especially professional.
