How to run cucumber in strict mode?

We recently found out that a bad merge caused one of our cucumber tests to report as running fine on our build system even though the underlying functionality was broken. It turns out that the test steps that were poorly merged were being reported as undefined but Cucumber was passing anyways. Yikes!

I see Cucumber-js (supports a "Strict" mode](cucumber/cucumber-js#211) where it will return exit code 1 if a step is undefined.

But for the life of me, I can't figure out how to pass "--strict" to chimp. Is there a way? If not, could you point me to where I could add one?

OK. I finally figured it out myself. You can't turn it on through the chimp.js config file. You have to pass it as a command line option:

chimp yourChimpConfig.js --strict
