Postman generates data based on datatypes in the OpenAPI spec: strings, numbers, booleans, etc - but the data will not look realistic. The video outlined a rudimentary test that checked if required fields were present.

Our TestGen feature generates realistic-looking data, such as dates, names, addresses, URLs, etc, automatically based on the field names, examples, and other API spec metadata. It does this automatically, without human intervention. The output is JavaScript, so if further customization is needed, such as using a response value of an API call in a subsequent request, you can do that.
