Question

We are using c# to return byte data of an mp3, but the mp3 is not yet encoded correctly, so we need a way to test it.

Currently we’ve built a page in our mvc that consumes the function and we simply run the url to try to load it into an mp3 player. Its a clunky way to do it, I’m sure. How should we really be testing for valid mp3 byte data?

Answer 1

Split system into pieces and test them separately:

• MP3 creation itself (as byte array/file) – can be tested by using some command-line “MP3 to something” converter or a library that can play MP3.
• generating url for client
• streaming given file to client (constant MP3 if you need to test in player, otherwise any byte array would do as long as it returned correctly with correct headers).
