Real Generator

Applies to TestComplete 15.40, last modified on March 25, 2022

The Real generator is used to generate real numbers with TestComplete. Using this generator type you can populate the desired Excel file or TestComplete Table variable with various real numbers and then use this data in your tests. For more information on preparing test data, see Preparing Data for Data-Driven Testing.

To open the generator

  1. Click on the Tools toolbar or select Test > Generate Data from the main menu to call the Data Generator wizard.

  2. In the wizard, select the data storage.

  3. On the Data Generation Options page of the wizard, for the needed value, select Real in the Data Generator column.

  4. Click Edit in the Parameters column.

  1. When adding a data-driven loop to a keyword test, select a table variable to store loop values.

  2. On the Variable’s Default Value page of the wizard, click on the toolbar.

Parameters

For the Real generator, you can specify the following parameters:

Generation mode

Generation mode - contains a drop-down list that allows you to specify a generation mode. The available modes are:

  • Random - Select this mode to generate random real number values within the specified range.
  • Sequential - Default. Select this mode to generate a sequence of values that will start with the value of the Minimum Value parameter (if the Increment value is positive) or with the Maximum Value parameter (if the Increment value is negative). The sequence's increment value is specified by the Increment value parameter. If the generated sequence goes beyond the specified bounds and the number of generated values is less than it is needed, the test engine repeats the generated sequence from the beginning as many times as necessary.

Minimum value

Specifies the lower bound of the real numbers to be generated. The default value of the parameter is -102.5.

Maximum value

Specifies the upper bound of the real numbers to be generated. The default value of the parameter is 102.5.
Note: The value of the Maximum value parameter must be greater than or equal to the value of the Minimum value parameter. Both parameters can be specified as an integer or as a real number.

Increment value

Specifies an increment value for the generated sequence. Note that if you want to generate a descending sequence, you should specify a negative value for this parameter. You can also specify a real number as the value of this parameter. The default value of the parameter is 2.5.
Note: This parameter is available only if you select the Sequential item in the Generation mode drop-down list.

Decimal places count

Specifies the number of decimal digits in the generated numbers. If you want to generate integer numbers only, you can either specify 0 as the value of this parameter or use the Integer data generator. The default value of the parameter is 3.

Duplicate each value … time(s)

Specifies how many times each generated value will be duplicated. The default value of the parameter is False.

After you specify the needed parameters, you can obtain the sample values that have been generated by the engine. The values are displayed in the Sample field.

Also, you can discard all the changes you made in the generator’s parameters and restore the parameters set by default. For this purpose, click Set Default Values below the Sample field.

If you are going to use the same settings in several variables or if you configure one generator in the same manner from time to time, it is much easier to save the selected generator with the specified parameter values as a user-defined generator. For this purpose, click the Save to User-Defined button below the Sample field.
