ert wants to collect the backtrace, but the test itself subverted that
(by setting debug-on-error to nil and then having an error in the test).

I don't see why Emacs should output a backtrace inside a test like that.

But Emacs will still output

Error running tests
  backtrace()
  #f(compiled-function () #<bytecode -0x1fecd686855e18f0>)()
  ert-run-tests-batch-and-exit()
  command-line-1(("-l" "/tmp/test.el" "-f" "ert-run-tests-batch-and-exit"))
  command-line()
  normal-top-level()

at the end.
