The remote server must be an instance of tcltest and it # must run the script found in the file "remote.tcl" in this directory. You # can start the remote server on any machine reachable from the machine on # which you want to run the socket tests, by issuing: # # tcltest remote.tcl -port 2048 # Or choose another port number. # # If the machine you are running the remote server on has several IP # interfaces, you can choose which interface the server listens on for # connections by specifying the -address command line flag, so: # # tcltest remote.tcl -address your.machine.com # # These options can also be set by environment variables. On Unix, you can # type these commands to the shell from which the remote server is started: # # shell% setenv serverPort 2048 # shell% setenv serverAddress your.machine.com # # and subsequently you can start the remote server with: # # tcltest remote.tcl # # to have it listen on port 2048 on the interface your.machine.com. # # When the server starts, it prints out a detailed message containing its # configuration information, and it will block until killed with a Ctrl-C. # Once the remote server exists, you can run the tests in socket.test with # the server by setting two Tcl variables: # # % set remoteServerIP # % set remoteServerPort 2048 # # These variables are also settable from the environment. On Unix, you can: # # shell% setenv remoteServerIP machine.where.server.runs # shell% senetv remoteServerPort 2048 # # The preamble of the socket.test file checks to see if the variables are set # either in Tcl or in the environment; if they are, it attempts to connect to # the server. If the connection is successful, the tests using the remote # server will be performed; otherwise, it will attempt to start the remote # server (via exec) on platforms that support this, on the local host, # listening at port 2048. If all fails, a message is printed and the tests # using the remote server are not performed. package require tcltest 2 namespace import -force ::tcltest::* # Some tests require the testthread and exec commands testConstraint testthread [llength [info commands testthread]] testConstraint exec [llength [info commands exec]] # If remoteServerIP or remoteServerPort are not set, check in the # environment variables for externally set values. # if {![info exists remoteServerIP]} { if {[info exists env(remoteServerIP)]} { set remoteServerIP $env(remoteServerIP) } } if {![info exists remoteServerPort]} { if {[info exists env(remoteServerIP)]} { set remoteServerPort $env(remoteServerPort) } else { if {[info exists remoteServerIP]} { set remoteServerPort 2048 } } } # # Check if we're supposed to do tests against the remote server # set doTestsWithRemoteServer 1 if {![info exists remoteServerIP]} { set remoteServerIP 127.0.0.1 } if {($doTestsWithRemoteServer == 1) && (![info exists remoteServerPort])} { set remoteServerPort 2048 } # Attempt to connect to a remote server if one is already running.
