The creation of sample test data for use in running automation test cases is known as test data generation. There are various techniques for creating test data generators that provide reasonable data that resembles production test data. If there is no existing data, you can use these tools.
The JSON Generator can create randomly A JSON file with any amount of values. Developers can use these values and QA to test their applications using various inputs. For convenience, the utility lets you save the generated JSON file as a .json file.
