## Test and preview
Before launching the scenario, you can preview how customers **are predicted** to flow through the nodes based on the conditions you defined. To do so, click on the "TEST" tab located above the canvas.
The test will dry-run the campaign as if it was executed immediately, taking into consideration all policies, A/B splits, unsubscribes, and other aspects. Bear in mind, however, that this is only an estimate and the individual aspects may change over time.
Please note that it is not possible to use this if you use an "On event" trigger since it is unpredictable. If you still want to see how customers would flow through the individual conditions, insert the "Now" trigger and then replace it again before launch.
Please bear in mind that the test and preview may not be absolutely accurate.
