Overview

Runner.run(features, opts)

where ‘features’ is an Array of file:line and ‘opts’ is a Hash of options:

:max        => Fixnum            number of workers (default: 2, pass 0 for unlimited)
:vnc        => true/false,Class,Array  children are launched with DISPLAY set from a VNC server pool,
                                 where the size of the pool is equal to :max. If passed a Class instance,
                                 this will be passed as the second argument to VncTools::ServerPool.
:record     => true/false,Hash   whether to record a video of failed tests (requires ffmpeg)
                                 this will be ignored if if :vnc is not true. If passed a Hash,
                                 this will be passed as options to RecordingVncListener
:notify     => object            (or array of objects) implementing the AbstractListener API
:out        => path              directory to dump output to (default: current working dir)
:log        => true/false        wether or not to log to stdout (default: true)
:format     => Symbol            format passed to `cucumber --format` (default: html)
:extra_args => Array             extra arguments passed to cucumber
:delay      => Numeric           seconds to sleep between each worker is started (default: 0)
:port       => String            port that the event server runs on
(default: 6333)
