Data Patterns for Random Generation

Data Patterns for Random Generation

You can enter data patterns from regular expressions to generate string and numeric data.
To generate numbers that contain special characters or any other operators, you use random string data generation technique. You can use the following operators to generate string data patterns:
. , \d , \w, (opt1| opt2|…..), {} , []
.
To generate numbers that do not contain special characters or any other operators, you use random numeric data generation technique. To generate numeric data, you can combine the following patterns:
\d, alternates (1|2|3|…), and [0-9]
. You cannot nest the alternates.
When you enter data patterns to generate the credit card number, Social Security number, and Social Insurance numbers, the generated data might not be valid. These numbers follow certain algorithms and you cannot use data patterns to generate valid numbers.
