All Implemented Interfaces:

DataMapper

public class IdentityMapper
extends Object
implements DataMapper

A mapper, that maps contents of a file to a set of parameters for test methods. Basically a CSV with no header and ordering of columns exactly like the one in the test methods. It uses the logic from @Parameters({}) for parsing lines of file, so be sure the columns in the file match exactly the ordering of arguments in the test method.
