title: How to use a different value each time postman runs a test through newman
body: <p>I have some tests in Postman that we are trying to automate. Currently whenever the QA people go in to test they manually change the body of the request to use a different ID number each time. </p>
  
  <p>What we want is for some kind of ability for that number to be changed each time using either a data sheet or some other way to increment the number. I have found the documentation for using a data sheet, the issue is this is more for if you want to use different values during iterations of a test. The next time you run the test though, it will go back to the first value and begin again. What I would need is a large list of values and for Postman to only pick the next value in the list each time the test was run.</p>
  
  <p>Example list:</p>
  
  <p>1234
  1235
  1236
  1237</p>
  
  <p>Today I run the test and it picks 1234. In 2 weeks when I run it again, it picks 1235. Three days after that I run the test again and it picks 1236.</p>
  
  <p>Is there any way to do this?</p>
