Hi,
I have a function streaming a zipreader to browser. It is like this.
func functionA(....)(body io.ReadCloser, err error){
// some logic to get a zipreader
body, pipeWriter := io.Pipe()
zipWriter := zip.NewWriter(pipeWriter)
go func(){
// err := functionB(zipReader, zipWriter)call another function to
prepare files and write to zipwriter
If err != nil{
zipWriter.Close()
_ = pipeWriter.CloseWithError(err)
return
}
zipWriter.Close()
pipeWriter.Close()
}()
return
}
My question is about unit test about this functionA. I have mock for
functionB. How do I write unit test for functionA with the mock functionB.
It seems my unit test does not work well when it goes into the goroutine.
Many thanks!
