How to run set of request before every request in Postman

Question

I'm writing test in Postman and I have multiple requests grouped like this:

Some test title:
- Create a user (set of "pre-requests"):
  - sending a few requests required to create a user, necessary to run tests
- Some action on a created user (here I'm testing what is in the test title)
  - one or more requests
Another test title:
- Create a user (set of "pre-requests", the same as in test 1.):
  - sending a few requests required to create a user, necessary to run tests
- Some action on a created user (not related ot test 1.)
  - one or more requests

To summarize I need to create a user before every request when I want to test something.

My question - How can I re-use "Create a user" set of requests without copying it?

Yes but is the user object always the same? i.e. same name, id, etc. Also does it need to execute for every request or just at the beginning of the collection? — so cal cheesehead
Every time I create a new user with different name: user_name_prefix + incremented number. User has to be created before set of request. e.g. 1) Create a user, 2) add some rights — wawr

This is how you can re-use the set of requests in pre-testcases and Test by setting environment variable and call it using eval function

pre-test case -

var Create_a_user = () => {
pm.sendRequest("http://mocktarget.apigee.net/json", function(err, res) {

    tests["Status code is 200"] = pm.expect(res).to.have.property('code', 200);
    console.log('firstName',res.json().firstName);      
});

pm.sendRequest("http://mocktarget.apigee.net/json", function(err, res) {

    tests["Status code is 200"] = pm.expect(res).to.have.property('code', 200);
    console.log("lastName - "+ res.json().lastName);
});

pm.sendRequest("http://mocktarget.apigee.net/json", function(err, res) {

    tests["Status code is 200"] = res.code === 200;
    console.log("city - "+ res.json().lastName.city);
});
};

pm.environment.set("Create_a_user", Create_a_user.toString());

Test -

eval(pm.environment.get("Create_a_user"))();

output -

firstName - John

lastName - Doe

city - San Jose

Disclaimer - Use Eval function carefully, it may fizzled up your code or its execution.
