How to print the content of TestError raised in Cocotb

Question

If I raise a TestError under cocotb test coroutine :

@cocotb.test()
def double_cmd(dut):
    ...
    raise TestError("Wrong CRC value found")

I know that error raised in test log, but I don't see the message "Wrong CRC value found":

12580176.01ns ERROR    Test Failed: double_cmd (result was TestError)
12580176.01ns ERROR    Failed 1 out of 1 tests (3 skipped)

Is there a proper way to print the TestError message in log ?

I would consider this a bug. Maybe you want to report it at https://github.com/potentialventures/cocotb/issues?

Activity in cocotb has picked quite a lot recently, so it will be worth reporting.

The only solution I found currently is to print the message before raising TestError:

@cocotb.test()
def double_cmd(dut):
    ...
    dut._log.error("Wrong CRC value found")
    raise TestError()

But maybe it's the thing to do?
