Testing RGB LED strip without a board?

Greetings,
Im trying to finish a project before Halloween and waiting for my Arduino Uno board to arrive. In the mean time Im wiring two RGB WS2811 LED strips. They are from china and was wondering if theres a way to test them, make sure they work and also if all my connections are good, without my board?

I would say without a processor to generate the data signal then no there is no other way of testing it.
