From 742584b0f2204497c7daaf3cde1c42aab6f7e55c Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Mon, 10 Oct 2022 12:56:24 -0700 Subject: tst_QTcpServer: Output useful more useful info for addressReusable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To try to figure out why QProcess::waitForReadyRead is returning false so quickly. Though we know it's going to be "Address in use". FAIL : tst_QTcpServer::addressReusable(WithoutProxy) 'process.waitForReadyRead(5000)' returned FALSE.
