How can we generate Dynamic email field and username for postman

Question

I need to generate a dynamic email address, username for API automation testing in postman. can you help me with this please.

Answer 1

I see two options on how you can get what you need.

1. Using already defined dynamic variables, such as timestamp: For example where you need a new email address, just use this:

   user_{{$timestamp}}@example.com
   

   The request will be sent with something like: user_1497475549@example.com

2. Define an variable in the pre-request script:

   var randomEmail = 'DO YOUR PREFERRED RANDOMIZATION HERE';
   pm.setEnvironmentVariable("email", randomEmail);
   

   and use that variable like {{email}} when sending the request.
