Detailed Description

Unit test for the I/O and Sockets demonstration.

This test verifies that the I/O and Sockets demonstration (implemented in the io_and_sockets module) terminates automatically when simulated input is provided and correctly accepts a client socket connection.

In test mode (with TEST_MODE defined), the demonstration bypasses the Windows-specific _kbhit() polling and uses std::getline() to read console input. The test simulates input by redirecting std::cin and provides a string ("client\nquit\n") that first allows a client connection and then instructs the demo to terminate.

Additionally, a separate client thread is spawned to connect to the server. If the connection succeeds, a flag is set. The test asserts that runDemo() returns 0 and that the client connection was successfully established.

Note

This test uses the TEST_MODE macro. Ensure that your implementation of runDemo() (in io_and_sockets.cpp) is modified so that when TEST_MODE is defined, it reads input using std::getline() rather than using _kbhit() on Windows.

Function Documentation

clientThreadFunction()

void clientThreadFunction

(

)

Client thread function that attempts to connect to the server.

The function waits briefly to allow the server to start up, then creates a client socket and attempts to connect to localhost on PORT. If the connection succeeds, the atomic flag is set.

main()

int main

clientConnected

std::atomic<bool> clientConnected {false}
