The test Is flaky and failing in CI occasionally. I was able to reproduce the failure easily by adding small delay just before the
SendFileAsync
it seems like if creating of the test file takes longer than usually this would fail.I was originally thinking about simple catching the ODE but at the end I decided to change the logic. By reading from the other end I assure the sending operation actually started. One byte does not really change the logic that assumes that large data would full the socket buffer and block.
