In Autotune experiments, there isn't a specific way to conduct pre-launch testing without starting the experiment. However, you can set up the experiment and thoroughly review its configuration before initiating it.
To test the experiment, you need to click the "Start" button to launch it. If you find that adjustments are necessary after the experiment has started, you have the option to pause the experiment, make the necessary changes, and then restart it.
Remember, the integrity of your experiment relies on careful setup and review before launching. Always ensure that your configuration is correct and meets your requirements before starting the experiment.
