Valid arguments are

  • –: Stops processing of options, treating remaining arguments as files

  • -rFEATURE: Requires FEATURE

  • -lLINE: Only runs expectation closest before or on LINE

  • -c: Reports test coverage

  • FILENAME: Loads expectations from FILENAME, relative to PWD

Parameters:

  • arguments (Array<String>) (defaults to: ARGV)
  • pwd (String) (defaults to: Dir.pwd)
  • io (IO) (defaults to: $stderr)

Raises:

  • (ArgumentError) —
