1. A method for test data generation using unique common factor sequencing, the method comprising:

  • loading a table for population with test data in a test data generation tool executing in a memory of a computer;

    selecting a column set of multiple columns in the table associated with a key to the table;

    assigning different cardinality sequence values to the columns in the set, wherein the cardinality sequence values do not share a common factor except for unity;

    generating data for a specified number of rows of each column in the column set according to a formula currentRowValue=((row_number−

    1)% cardinality_value)+1;

    additionally generating random data for other columns of the table without regard to any particular cardinality sequence value; and

    persisting the table for use in database testing.
