Is there a way to test a canbus tester without actual can signals?

I have a can bus testing station but no can signals readily available..

You can use the virtual CAN interfaces, see

Chapter 6.4

or you can emulate complete machine with CAN interfaces.
But only three SJA1000 PCI based cards are emulated till
now:

  dummy SJA1000 mapping to PCI for testing, 

  CAN bus Kvaser PCI CAN-S (single SJA1000 channel)

  and PCM-3680I PCI (dual SJA1000 channel) contributed
  by Deniz Eren some weeks ago

Git with CAN emulation for QEMU-2.4 is available at

  https://github.com/CTU-IIG/qemu/tree/merged-2.4

Some basic documentation and pointer to RTLWS article
