A simple mock object that provides the ActiveRecord method signatures read_attribute(key) and write_attribute(key,val), and simple record finder signatures find(id) and find(:all).

Example:

mock = ActiveRecordMock.new
mock.write_attribute('foo','bar')
mock.read_attribute('foo') => 'bar'

Example of initialize with attributes:

mock = ActiveRecordMock.new(:foo => 'bar', :goo => 'car', :hoo => 'dar')
mock.read_attribute(:foo') => 'bar'
mock.read_attribute(:goo') => 'car'
mock.read_attribute(:hoo') => 'dar'

Example of creating mock users:

anne = ActiveRecordMock.new(:id => 123, :name => 'Anne')
beth = ActiveRecordMock.new(:id => 456, :name => 'Beth')
cate = ActiveRecordMock.new(:id => 789, :name => 'Cate')

Example of mock finder creation:

ActiveRecordMock.find=[anne,beth,cate]

Example of mock finder retrieval of records by id:

ActiveRecordMock.find(123) => anne
ActiveRecordMock.find(456) => beth
ActiveRecordMock.find(789) => cate

Example of mock finder retrieval of all records:

ActiveRecordMock.find(:all) => [anne,beth,cate]
