[Contiki-developers] Cooja no-gui test

[Richard Figura]

Hello,

I try to start a saved test via bash without using the gui (or even better
without the appearance of the gui).
I am very new to contiki and cooja, so perhaps I made a basic mistake.

I have created a new cooja-plugin that implements "plugin" and that has the
PluginType:
@PluginType(PluginType.COOJA_STANDARD_PLUGIN)

In the Plugin-Constructor I call:
gui.doLoadConfig(false, true, file);

As a result I get the following error:

run:
[java] INFO [AWT-EventQueue-0] (GUI.java:2824) - Loading external tools
user settings from: /external_tools_linux_64.config
[java] INFO [AWT-EventQueue-0] (Simulation.java:354) - Simulation random

java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

Of course the plugin is added to the cooja_default.config, cooja is
recompiled and the file exists.

Can anybody help me with this?
Is this the right way for non-gui testing?

Thanks,
Richard Figura

Hi Richard,

The recommended way for non-GUI simulation is creating so called
"Contiki test scripts".
It is also possible to create - like you did - a gui standard plugin
which controls a simulation, however, this is significantly more difficult.

Contiki test scripts consists of a simulation config and a test script
(currently in JavaScript).

To try it out:
* Start Cooja with GUI (ant run)
* Start the plugin "Contiki Test Editor" plugin, and click "Import
Contiki test"
* Import any of the tests listed, for example the cooja_helloworld test
* The simulation config is now loaded (includes Contiki compilation -
may time some time), and the test script is shown in the upper frame
* To run the test, activate the script and start the simulation: Click
"Activate" in the plugin, and start the simulation as usual (Control Panel)
* Observe test output in the lower window

Non-GUI test:
* The same test can be started without GUI by the following command:
/tools/cooja/contiki_tests > bash RUN_TEST cooja_helloworld
* cooja_helloworld.log contains the test output

The Contiki tests operate on mote output, so to create your own test the
simulated nodes must print information that the test script can understand.

Hope this helps,
Fredrik

Hi Fredrik,

thank you very much!
This helps me a lot :-)
