You could make your robot follow a predefined path in his own odometry frame. By comparing its real movements VS the predefines ones, you can have a basic idea of how fine is your odometry.

You could for instance make your robot follow a 1m square like this:

Move forward 1m
Stop
Rotate +90 Deg.
Rapeat 4 times

And compare the real movements of your robot VS the odometry estimate. Check this tutorial, it shows how to send simple goals in the robot's odometry frame.

You could also manually drive your robot along a predefined path (using a joystick for example) and check the odometry estimate.
