Is there a way to run/test functions & triggers?

You can test a trigger by telling it to use the "Show Notification" action instead of your more complicated function.

You can test a function by assigning it a "Key Combination" and then pressing that on the keyboard. Or if the function is expecting a specific window to run on, you could add a TitleBar button and click that.

can you give me an example

I'm not sure I understand your confusion, but here are some screenshots, I guess...
