Weighted List generators

Last modified: April 3, 2025

The Data Generator tool provides the following types of weighted list generators:

• Weighted List Generator (simple): Generates flat values according to the specified ratio.
• Weighted List Generator (nested): Generates values from nested value lists according to a specified ratio.
• Weighted List Generator (ranged): Generates values in a specified range.
• Weighted List Generator (regexp): Generates regexp data according to the specified ratio.

In the Fill settings section, you can set up basic and custom settings.

Custom settings

Add a Value: Adds a new empty line in the Value field and a default weight value 10.

Delete current value: Deletes a line and navigates a focus to a subsequent line.

Clear values list: Clears all values from the data grid.

Data Grid

A data grid represents a table of data to populate. The data grid of each weighted list generator includes the following columns:

• Order Number
• Value: Contains generated values.
• Weight: Contains weight ratios of the values
• Percentage (%): Displays the percentage of occurrences of each value in the column with respect to the rest of the values.

Weighted List Generator (nested)

The generator contains two data grids: a main data grid and a nested data grid. The main data grid is non-editable except for the Weight column. When clicking the Value column of the main data grid, the nested data grid appears. In the nested data grid, the Value and Weight columns are editable. The Percentage (%) column is a calculated column.

At the bottom of the nested data grid, the following controls are displayed: Load values from File, Save values to File, Add a value, Delete current value, and Clear values list.

Weighted List Generator (ranged)

The data grid in the ranged generator contains five columns: Order Number, From, To, Weight, and Percentage (%). The From column includes initial values of a value range, and the To column includes end values of the value range. For date values, clicking the From and To columns opens a calendar window.
