File Extension

The file extension identifies the file type, such as .mp3 or .wav for audio files. It's important for ensuring the correct handling of the file by browsers and devices.

Why do we test it?

An incorrect or unsupported file extension can result in playback errors or complete failure to load. This test ensures that the file extension is valid and appropriate for the ad, reducing the risk of errors and improving cross-platform compatibility. It's essential to have the right extension to avoid rejection from ad networks or issues during ad serving.
