I’ve never done this before, so off the top of my head here’s how I quickly performed the action you wanted:
In the example I’m calling one GET request that just returns user details.
The example URL is:
http://localhost:3000/users/{{userId}}
And here’s an example response:
Before we begin, I have 3 environment variables:
“userIds” which has an array of User IDs.
[1, 2, 3, 4, 5, 6]
“counter” which will be a number. This will be set to 0 in a previous request.
Finally, we have a “userId” which is what’s used in the URL. We’ll have some logic in place to pull the correct userId from our “userIds” array.
Down To The Nitty Gritty!!:
In the Pre-Request Script tab I’m taking the current value of our “counter” environment variable.
I’m also performing a JSON Parse on the “userIds” array as Postman saves as env variables as strings.
So! Our “userId” variable will be set to the User ID in our “userIds” array based on the current value of “counter” (I hope that made sense…)
There are lots of comments in the code snippet shown.
In our Tests Tab:
Again, I’m performing a JSON Parse on our “userIds” array.
And I’m taking the current value of our counter variable again.
I’m increasing the value of “counter” by 1 with each request.
I have a condition, that checks if “counter” is NOT equal to the length of the array (minus 1)
If it’s not, I’m using postman.setNextRequest() to hit the same request again (But remember, our counter variable is now greater than before)
You can probably tell this is pretty rushed as I’m at my place of work xD
Good luck! Hope this makes sense.
I’m sure there are MUCH better/cleaner ways of doing this.
