To test the applications, developers, and testers require a lot of data in the database. The cost and difficulty of manually putting data into the database are prohibitive.
It will also take time to write a script to insert data into the database. As a result, we will need some tools known as Test data-generating tools to input data into the database. Tools for creating automation test data assist testers with load, performance, stress, and database testing. These programs can produce data that can be incorporated into other databases.
Some solutions also provide security to the database by substituting fake data for sensitive information. It protects private data. These programs also offered the option to output the created data in SQL scripts. Thus, these technologies play a significant role in the testing and creation of apps.
Top Tools for Generating Test Data
The most well-liked test data generation tools on the market are given below.
LambdaTest
LambdaTest’s free-to-use test data generator tool replaces privacy-sensitive data including names, corporations, IBANs, social security numbers, etc. It helps web developers and testers in producing qualitative and sophisticated data sets.
