The Velveteen Rabbit (or How Toys Become Real) is a children's book written by Margery Williams (also known as Margery Williams Bianco) and illustrated by William Nicholson.
 It chronicles the story of a stuffed rabbit and his desire to become real, through the love of his owner.
 The book was first published in 1922 and has been republished many times since.
Margery Williams Bianco (22 July 1881 in London, England – 4 September 1944 in New York City) was an English-American author, primarily of popular children's books.
 A professional writer since the age of nineteen, she achieved lasting fame at forty-one with the 1922 publication of the classic that is her best-known work, "The Velveteen Rabbit" (1922).
The Augustinian hypothesis is a solution to the synoptic problem, which concerns the origin of the Gospels of the New Testament.
 The hypothesis holds that Matthew was written first, by Matthew the Evangelist (see the Gospel According to the Hebrews and the Jewish-Christian Gospels ).
 Mark the Evangelist wrote the Gospel of Mark second and used Matthew and the preaching of Peter as sources.
 Luke the Evangelist wrote the Gospel of Luke and was aware of the two Gospels that preceded him.
 Unlike some competing hypotheses, this hypothesis does not rely on, nor does it argue for, the existence of any document that is not explicitly mentioned in historical testimony.
 Instead, the hypothesis draws primarily upon historical testimony, rather than textual criticism, as the central line of evidence.
 The foundation of evidence for the hypothesis is the writings of the Church Fathers: historical sources dating back to as early as the first half of the 2nd century, which have been held as authoritative by most Christians for nearly two millennia.
 Adherents to the Augustinian hypothesis view it as a simple, coherent solution to the synoptic problem.
RSpec is a 'Domain Specific Language' (DSL) testing tool written in Ruby to test Ruby code.
 It is a behavior-driven development (BDD) framework which is extensively used in the production applications.
 The basic idea behind this concept is that of Test Driven Development(TDD) where the tests are written first and the development is based on writing just enough code that will fulfill those tests followed by refactoring.
 It contains its own mocking framework that is fully integrated into the framework based upon JMock.
 The simplicity in the RSpec syntax makes it one of the popular testing tools for Ruby applications.
 The RSpec tool can be used by installing the codice_1 gem which consists of 3 other gems namely codice_2 , codice_3 and codice_4
