Description

The RandomGen Generator randomly generates a number within a range. For example, you can use it to generate random ages between 18 and 65.

• Generator Parameters
• Example 1 - Generate Random Numbers Between 1 and 1000 with No Unique Limit
• Example 2 - Generate Random Numbers Between 1 and 10 with a Unique Limit of 2
• Error - Exhausted Attempts to Find the Next Valid Random Value

Generator Parameters

The following parameters may be configured for the RandomGen Generator. Items with an asterisk* are required.  

• startRange* - Defines the start range of the random Generator.
  
• endRange* - Defines the end range of the random Generator.
  
• uniqueLimit - Defines the number of times a given value is allowed to be regenerated. The value should be 1 or greater. 
  • If uniqueLimit is left empty, there is no limit to how many times a value can be regenerated.
  • If a value is entered, then each number within the range can be generated that number of times.
    • If 1, each value will only be generated once.
    • If 10, each value will be generated ten times. 
  • The uniqueLimit does not apply to dynamic start and end range values that change per row.
    
• seed - Using the seed will ensure that the same random data is generated each time data is generated.
  
  

Example 1 - Generate Random Numbers Between 1 and 1000 with No Unique Limit

Sample Output

Example 2 - Generate Random Numbers Between 1 and 10 with a Unique Limit of 2

For this example, the Domain loopCount has been set to 15 records to ensure the possibilities are not exhausted during test data generation. 

Each number ranging from 1 to 10 can only be generated 2 times. 

Sample Output

The following output has been generated as a delimited file:

Error - Exhausted Attempts to Find the Next Valid Random Value

You will receive an error if a value is present for the uniqueLimit parameter, and the loopCount exceeds the maximum number of values generated based on that limit.

For example, the range is between 1 and 20, and the uniqueLimit is '1', while the Domain loopCount has been set to '20'. 

!!!!! An Error Has Occurred !!!!!
strings: Exhausted attempts to find the next valid random value from range of 1 to 20.
