Instance Method Details

#describe_cli(subject_name, context_options = {}, &block) ⇒ Object

Describe a command line interface This method basically behaves like Bacon::Context.describe, but it provides automatically the methods #subject, #file_tree_spec_context, #cli_spec and #file_spec.

Parameters:

  • subject_name (String) —

    the subject name will be used as first argument to initialize a new Subject, which will be accessible in the spec by #subject.

  • context_options (Hash<Symbol,String>) (defaults to: {}) —

    the options to configure this spec context, could be one or more of:

    • :executable: the executable used to initialize Subject if not given, will fallback to param subject_name.

  • ] (Block<() -> ()) —

    block the block to provide further sub-specs or requirements, as known from Bacon::Context.describe

    # by the parent context. We have to ensure that the methods will be
    # accessible by the child contexts by defining them as singleton methods.
