Overview

A charz session contains a collection of the final combinations of charz object (routines/profiles) and user options to determine how and what charz tests should be created the session should be checked in your interface to determine the current status and can be queried to make charz generation decisions

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object (private)

Instance Attribute Details

#current_instance(options = {}) ⇒ Profile

Returns Set when looping over instances via #loop_instances. The interface can query the charz_instance for more detailed info.

Returns:

  • (Profile) —

#defaults ⇒ Hash

Returns list of values to instantiate the inherited attributes from Profile with if not altered by the session update.

#update(charz_tuples) ⇒ Object

Takes a CharzTuple and queries it to setup an instance’s attributes the attributes values can be set from 3 different sources, in order of priority (first is most important):

- options
- charz object (Profile or Routine)
- defaults

If the resulting session is invalid, @valid will turn false. Otherwise, the session becomes active
