Test Data Generator - Seed Lists

The following functions are available to generate synthetic test data. When you parameterize your tests, you can assign these functions as variable values instead of using static hard-coded values. For related functions, see also Test Data Generator - JavaScript Methods and Test Data Generator Functions.

Seed Lists

The included seed lists contain common example strings to help you generate realistic test data, such as names of weekdays, months, persons, banks, companies, places, and so on. To learn more, see the randFromSeedList() / randlov() or valueFromSeedlist() functions.

BlazeMeter ships with the following seed lists included:

Multi-Column Seed Lists

Some seed lists contain several columns of congruent data, such as a street name with matching postal code, county, and city name, that you can use to test form validation or map lookup. Their names end in "-multicol".

The randFromSeedlist(seedListName, column, percnull) function has an optional column parameter to select these extra columns. By default, the function only returns the first column.

Examples:

  • randFromSeedlist("femalenames")
    Returns "Jenny"
  • randFromSeedlist("usaddress-multicol", 1)
    Returns "325 Beacon St"
  • randFromSeedlist("usaddress-multicol", 2)
    Returns "Boston"
  • randFromSeedlist("usaddress-multicol", 1, 20)
    Returns "325 Beacon St" or null with a 20% probability
  • valueFromSeedlist("usaddress-multicol",1,4) + " " + valueFromSeedlist("usaddress-multicol",1,2)
    Returns the matching values "02215 Boston" because they are both taken from row 1.
