configure Joom Donation to use PayPal Sandbox

How do I configure Joom Donation to use PayPal sandbox instead of the regular PayPal site?

I need to test before I launch this live. Again, I don't see this configuration option anywhere in the component settings, nor do I see this information in the documentation.

Please advise.

Thanks

Hi

Please go to Joom Donation -> Payment Plugins, see the os_paypal payment plugin. CLick on the plugin, you will see a parametter which allows you to run it in Test Mode !
