It is possible to test rules using the ‘Content Simulator’. Once you have created a rule. Click on the ‘play’ icon:

 

This will take you into the Context Simulator.

The context simulator allows you to test different criteria and check that the correct image is displayed.

In this example, Android has been selected as the ‘context’ device. You’ll notice that the rules work from the top down, so the first device ‘iPhone’ is ‘not matched’ but the second device, ‘Android’ is ‘matched’.

The conditions built in to the rule will automatically appear on the right hand side. For example, if you are using the Date/Time rule, you will be able to set the time and date to simulate the context.
