A couple things I see are firstly, those BECs have built-in BECs. The BEC provides 5 volt power to your flight controller BUT you only need one providing power. So the 3 wires going from the ESC for motor 1 to your flight controller are correct, but for motors 2, 3 and 4, you need to remove the red (positive) wire and only have the brown and yellow (negative and signal) from your ESCs to flight controller.
Secondly, you can program most things in Cleanflight with your flight controller connected just by the USB but to spin up your motors in the motor testing tab, you also need to have your battery connected. By your pic, it doesn't look like your battery is connected, correct?
