Instance Method Details

#[](key) ⇒ Object

Provides access to attributes, if available, as @node much like in chef cookbooks Use .keys to see if a key exists

# File 'lib/spec_helper.rb', line 59

def [](key)
  return nil if @attributes == nil
  # Raise exception so test issues are clearly displayed in rspec output (puts is displayed before test output, difficult to identify which test it comes from)
  raise "Missing attribute key '#{key}', got #{@attributes.keys}" if not @attributes.key?(key)
  @attributes[key]
end

#attributes ⇒ Object

Attributes defined specifically on the node, not aggregated like in chef runs

host is assumed to be equivalent with node name now, but we could read it from attributes, see ticket:1017

end

#shell ⇒ Object

return command line access, instance of TestbeatNodeRsh, or false if unsupported This is probably easier to support than get_bats; on vagrant nodes we have ‘vagrant ssh -c’
