Class GenVectorTestCode

java.lang.Object
  org.apache.hadoop.hive.ant.GenVectorTestCode

public class GenVectorTestCode
extends Object

GenVectorTestCode. This class is mutable and maintains a hashmap of TestSuiteClassName to test cases. The tests cases are added over the course of vectorized expressions class generation, with test classes being outputted at the end. For each column vector (inputs and/or outputs) a matrix of pairwise covering Booleans is used to generate test cases across nulls and repeating dimensions. Based on the input column vector(s) nulls and repeating states the states of the output column vector (if there is one) is validated, along with the null vector. For filter operations the selection vector is validated against the generated data. Each template corresponds to a class representing a test suite.
