Generating test data includes: reading values occurring in at least one field of multiple records from a data source (102); storing profile information including statistics characterizing the values; generating (206) a model (300) of a probability distribution for the field based on the statistics; generating (206) multiple test data values using the generated model such that a frequency at which a given value occurs in the test data values corresponds to a probability assigned to that given value by the model (300); and storing (212) a collection of test data (114) including the test data values in a data storage system (116). |
