// Fuchsia doesn't support stdin stream for packaged apps, and stdout from
// run-test-suite not only has extra emissions from the Fuchsia test
// infrastructure, it also merges stderr and stdout together. Combined, these
// mean that when running content_shell on Fuchsia it's not possible to use
// stdin to pass list of tests or to reliably use stdout to emit results. To
// workaround this issue for web tests we redirect stdin and stdout to a TCP
// socket connected to the web test runner. The runner uses --stdio-redirect to
// specify address and port for stdin and stdout redirection.
//
// iOS is in a similar situation where the simulator does not support the use of
// the stdin stream for applications. Therefore, iOS also redirects stdin and
// stdout to a TCP socket that is connected to the web test runner.
