Chrome: redirect console.log to stdout

I am investigating easy ways to reuse tests that output the TAP format.

I want to be able to start Chrome from the command line and capture console.log output

If I have the following file called index.html

<script>
  console.log('beep boop!')
</script>

...can I then capture from the command line by doing something like this:

# start-crome --flag > out.txt

...and have out.txt contain "beep boop!"?

EDIT: Yes there are other questions that cover saving console.log to file manually. I want to pipe console log to stdout, so that debug information can be analysed in an automated unix setting
