Note than in order run a single feature file, it appears you need to use the fully qualified path to the file like so:
vendor/bin/behat --config /path/to/behat.yml $(pwd)/path/to/test/behat/file.feature
You can also run specific scenarios within the file by supplying a starting and (optional) ending line number:
vendor/bin/behat --config /path/to/behat.yml $(pwd)/path/to/test/behat/file.feature:123-321
