Test data generators with valid checksums

Forms in Polish systems check PESEL, NIP or REGON numbers, so made-up values fail validation. Testosaur generates valid ones, a new value in every run, and types them into the application during automated tests.

Generators

Generator	Options
PESEL	range of birth dates, gender
NIP	–
REGON	9 or 14 digits
Bank account (NRB) and IBAN	–
ID card number	–
Email	domain
Phone number	with or without the +48 prefix
First name, last name	gender
Postal code	–
Date	range and format, e.g. yyyy-MM-dd or dd.MM.yyyy
UUID	–

Every number with a check digit is calculated the way the real one is, so it passes the same validation as data from production.

Your own data

List: paste values one per line; every run takes a random one. Good for product names, cities or test logins.
Pattern: describe the value with a regular expression, for example FV/\d{4}/[0-9]{2} for invoice numbers. Each value is checked against the pattern before it is used.

How to use them

Create a source in Settings → Test data and check a few sample values with Preview.
In an automated test case, set a "type text" step to take its value from the source.
Run the test. The step results show which value was typed.

A source that is used by a step or by a test plan cannot be deleted, so plans keep working.
