@mijicd this is on develop somehow. I looked into test and assertion passed. Could you help me with that since I don't have experience with testz? |

@pshemass I'll take a look at it. |

Why write a single 0 byte here? I haven't been able to figure it out.

damm, I need to push my latest change because I got rid of that. The Idea was that you need to use connection to get exception that is closed already because TCP connection don't know that it's been closed unless you use it. so I send whatever :)

@quelgar please look into latest commit.

Maybe extract it to some helper function as clean-up.

I gave this branch a run and noticed it doesn't close down the listening socket. This means if you execute test:run a second time in the same sbt session, you get an address already bound error. I think you need to use bracketing to make sure the cleanup happens. Very roughly:
def server: IO[Exception, Boolean] = {
for {
address <- inetAddress
_ <- AsynchronousServerSocketChannel().bracket(_.close.ignore) { server =>
server.bind(address) *> server.accept.bracket(_.close.ignore) { worker =>
worker.read(3) *> worker.read(3)
}
}
} yield false
}.catchSome {
case ex: java.io.IOException if ex.getMessage == "Connection reset by peer" =>
ZIO.succeed(true)

great catch I will update this.
isOpen is useless in case of detecting if connection was reset by peer. I decided to make decision based on number of bytes that is read from channel. -1 means end-of-stream.
