request/question: How to access debug log stream

[BusaniNdlovu]

Greetings. Thank you for the amazing library. I'm curious as to how to access this libraries standard output and error stream. Is it printed and ephemeral or is it written to a file. My intention is to assert in my tests whether something was logged. Any insight would be much appreciated.

Definitely ephemeral, but you can override the .log property in order to process debug messages. However, it's not the most elegant API admittedly.

Check out #556 which would solve a lot of the testing needs, too. Not sure when it will be implemented.

Does that help?

[BusaniNdlovu]

Thank you for the quick response. Yes, your insight is extremely helpful. I'll explore further. Else I'll implement some version of #192 .

Right now the ugly hack for Node would be to pass all of those strings to strip-ansi and then pass them to a file.

Sounds fun. I'll get my hands dirty. Also, it just occured to me that it may prove effective to wrap a sinon spy around the debug function, then do a getCalls().args on it. I'll let you know how that pans out for the benefit of others. But otherwise you may close the issue.

You can definitely do that.

Keep in mind, however, that depending on how you're using debug, it might be an anti-pattern to test against what's passed to debug.
