Test::Deep uses the Test::Builder framework. .PP Test::Deep gives you very flexible ways to check that the result you got is the result you were expecting. At its simplest it compares two structures by going through each level, ensuring that the values match, that arrays and hashes have the same elements and that references are blessed into the correct class. It also handles circular data structures without getting caught in an infinite loop. .PP Where it becomes more interesting is in allowing you to do something besides simple exact comparisons. With strings, the \f(CW\*(C`eq\*(C'\fR operator checks that 2 string
