This program tests the startup time of the given application with and
|
|
without launcher.
|
|
|
|
Requirements:
|
|
1. DISPLAY environment variable must be set correctly.
|
|
2. DBus session bus must be running.
|
|
3. DBus session bus address must be stored in /tmp/session_bus_address.user.
|
|
4. Given application supports launcher with .launcher binary in /usr/bin/.
|
|
5. launcher application should be installed.
|
|
|
|
Usage: test-func-launcher <launcherable application>
|
|
|
|
Example: test-func-launcher /usr/bin/fala_ft_hello
