List of the best paid and open source free Test Data Generation Tools with features and comparison:
Developers and testers need a large volume of data in the database in order to test the applications.
Manually inserting data into the database is not an affordable option by price and by efforts as well.
Writing a script to insert data in the database will also be a time-consuming option. Hence, we will require some tools to insert data into the database and those tools are called Test data generation tools.

Types of Test Data Generator
The 4 types of test data generation tools include:
Test data generation tools help the testers in Load, performance, stress testing and also in database testing. Data generated through these tools can be used in other databases as well.
Some tools also provide security to the database by replacing confidential data with a dummy one. At the same time, it also preserves the confidential data. These tools also provide an option to output the generated data in the SQL scripts. Hence in this way, these tools help a lot in testing and development of applications.
Load, performance and stress testing are just impossible without the help of these tools. These tools are easy to use and in turn, save a lot of time. It not only saves time for creating scripts, but it has also made data generation easy. With just a few simple clicks, you will be able to create a large volume of data.
A lot of tools provide complex database features like Referential integrity, Foreign Key, Unicode, and NULL values. With free or open source tools you may not get all the required features, but those companies also provide advanced features by paying some cost.
Lots of test data generation tools are available in the market. However, while selecting a tool you must consider some factors like supported databases, data generation methods, data types support, operating system support, and cost etc.
