How to test image upload stream with supertest and jest?

Posted by Jennifer | Updated on

This should work. To pipe data to a request you have to tell the readable stream to pipe to the request. The other way is for receiving data from the server. This also uses done instead of async as pipes do not work with async/await.

Also worth nothing is that by default the pipe will call end and then superagent will call end, resulting in an error about end being called twice. To solve this you have to tell the pipe call not to do that and then call end in the on end event of the stream.
