Instance Method Details

#behaves_like_a(name, *args) ⇒ Object

Works like ‘behaves_like`, but takes arguments for the shared example

# File 'lib/CLIntegracon/adapter/bacon.rb', line 57

def behaves_like_a(name, *args)
  instance_exec(*args, &Bacon::Shared[name])
end

#cli_spec(spec_dir, *args) ⇒ String

Note:

This expects that a method ‘file_tree_spec_context` is defined, which is returning an instance of FileTreeSpecContext.

Ad-hoc defines a set of shared expectations to be consumed directly by ‘behaves_like`. See the following example for usage:

behaves_like cli_spec('my_spec_dir', 'install --verbose')

def cli_spec(spec_dir, *args)
  file_spec spec_dir do
    output = subject.launch(*args)
    status = $?

    it "$ #{subject.name} #{args.join(' ')}" do
      status.should.satisfy("Binary failed\n\n#{output}") do
        status.success?
      end
    end
  end
end

#file_spec(spec_dir, &block) ⇒ String

Note:

This expects that a method ‘file_tree_spec_context` is defined, which is returning an instance of FileTreeSpecContext.

Ad-hoc defines a set of shared expectations to be consumed directly by ‘behaves_like`. See the following example for usage:

behaves_like file_spec('my_spec_dir') do
  # do some changes to the current dir
end

Raises:

  • (ArgumentError)

#file_tree_spec_context(&block) ⇒ FileTreeSpecContext

Note:

On first call this will create a new context on base of the shared configuration and store it in the ivar ‘@file_tree_spec_context`.

Get or configure the current context for FileTreeSpecs
