Reproducible fake rows for testing

Developers and testers can generate sample rows when a scenario must be rerun with reproducible data instead of changing inputs.

Create reproducible fake rows for testing, allowing the same example dataset to be generated again whenever a scenario needs to be repeated.

How to use

Enter the number of fake rows you need for your test scenario.
List the columns you want, such as name, email, city, date, integer or uuid.
Run the generator to create a reproducible set of rows for your testing needs.
Copy the output and use it in your test database or automated scenario.

Example

A common example asks for a few rows with columns such as name, email, city, date, integer and uuid. After generation, check that every column is filled and that the values remain clearly fictional, with no risk of resembling real personal data.

Input

4
nom, email, ville, date, entier, uuid

Output

nom;email;ville;date;entier;uuid

Limits and formats

The generated data is fictional and must not be used as real information.
The tool does not connect to any database or replace a generator tied to your production schema.
Some column names may not be recognized if the tool does not support that type.
Check the format of dates, identifiers and addresses before loading them into your tests.

Where processing happens

Fake rows are created directly in your browser. The parameters you enter stay on your device and are not sent to an external service. You can generate test data without any content being transmitted.

Frequently asked questions

Will the same data be generated every time?

The tool aims to produce reproducible rows for repeating a scenario. The result still depends on the parameters you enter and the page version. For a critical test, save a copy of the generated set if you need to reuse it exactly.

Can I generate valid email addresses?

The tool can produce fictional addresses to fill an email column. They should not be used to send mail. Check that they match the format expected by your test application.

What if a requested column does not appear?

The column name must match a type recognized by the tool. Try a simple wording such as name, email, city, date, integer or uuid. Run the generation again and check the header of the result.
