These free tools let you generate data for CSV, Excel, XML, JSON, SQL and more! The data generator makes getting random fake data to test your application very easy. We recently released DataFairy, a free tool that generates test data. But first, let me tell you the story of how it came about. This is the story of.

Test data generation

It is similar to the goal-oriented generator. Intelligent test data generator - This type depends on sophisticated analysis of the code to be tested in order for it to guide the search for test data. This may test data generator test data more quickly but the analysis portion requires great insight in order to anticipate the different situations that may arise.


I've created this because I needed something like it and hadn't found it before. It's currently not high on features eg.

If you need to generate credit card test data generator you might want to try this other tool. Take this Visa card number: The first thing you need to do to see if you can validate the number is to double the alternating digits starting with the first digit in the sequence.

Now add it all up. In this case it is, so the number is valid. You need test data generator sort of computational algorithm to validate credit card numbers at scale. But credit card numbers are relatively easy pieces of data to get right.

Database test data generator - Fill your database with random test data!

Verifiable profiles need different kinds of data that relate to each other logically Credit card numbers are relatively easy to generate, because they only relate to themselves. But personal identity numbers often relate to other things about a person.

Take test data generator Swedish personal identity test data generator, practically called the personnummer. Photo by Jonathan Brinkhorst on Unsplash: The format of a personnummer is slightly different than that of a credit card.

It is a 10 digit number split into a six digit section and a four digit section connected by a hyphen. Swedes over the age of replace the test data generator in their personnummer with a plus sign.

Of the second 4 digit section, the first three are a serial number. Mockaroo Most test data generator like Ruby on Rails have great data mocking libraries, but not everyone is a programmer or has time to learn frameworks.

You can download random data programmatically by saving your schemas and using curl to download data in a shell script via a RESTful url.

Test data generator, you can apply formula to any data type, custom frequencies for lists, restrict locations to specific countries, and more.


It is packed with over built-in generators with a sensible configuration that allows to emulate column-intelligent real world test data. All you need to do is select tables to generate data for, choose a generator and adjust generation properties, and click test data generator populate button to get the results.

The program supports foreign keys for generation of consistent data across multiple tables, and check constraint for generation of consistent data across a single column or multiple columns of a table. It also allows disabling triggers and constraints to test data generator interference with database logic.

It offers unique features to produce realistic datasets by combining 30 generation rules.
