launchapp ('<application binary name>'[, argument] [,use additional environment variables for accessibility])
second and third arguments are optional. environment default argument is 1. So the GTK_MODULES and GNOME_ACCESSIBILITY will be set and added to the enivronment variable. Currently the second argument is applicable only when the test is run in local environment.
Second argument is a list, if executed from local session and the same argument is used as sleep time for remote session, but as a single integer value.
NOTE: Incase of remote session, the command line arguments should be part of application name
Application name specified as an argument will be launched.
