Using momentjs-timezone in Postman

External libraries can be executed in postman if CDN equivalent of these libraries are available.

You can get CDN in equivalent from websites like: https://cdnjs.com/

Now to use momentTZ in postman, copy the below code into script section and execute it once and then comment out:

This will store the CDN equivalent of momentTZ and momentJS libraries to environment variables.

pm.sendRequest("https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.33/moment-timezone-with-data-2012-2022.min.js", (mtzErr, mtzRes) => {
pm.sendRequest("https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js", (mjsErr, mjsRes) => {
//you have to initialize the momentjs to make momenttz work so we are storing both into a variable
pm.environment.set("momentjs", mjsRes.text());
pm.environment.set("momenttz", mtzRes.text());
})
})

Now you initiate the libraries in either of the two approaches:

First Approach:

Now comment out the above code you don’t need it anymore. Now you can use momenttz anywhere in your collection’s script sections as :

eval(pm.environment.get("momentjs"));
eval(pm.environment.get("momenttz"));
console.log(this.moment.utc().tz("America/Los_Angeles", "UTC").format())

in this approach, the libraries are initialized in the local scope, so if you want to use them again then you have to run the 3 lines of code again in other script sections whenever it’s used.

Second approach:

new Function triggers function in the global scope. so you just have to execute the first two lines only ones in your collection run and it will be available globally throughout:

Add in first scripts pre-request script:

(new Function(pm.environment.get("momentjs")))();
(new Function(pm.environment.get("momenttz")))();

Now you can use momentTZ library anywhere as :

console.log(moment.utc().tz("America/Los_Angeles", "UTC").format())

How to run postman requests using Tags

Get all requests in the collection:

you can also get information about all the requests in a collection by using :

https://api.getpostman.com/collections/{{collection_UUID}}

to get uuid and api key goto :

https://app.getpostman.com

Now for generating api key >

goto account settings > api key and generate api key.

to get collection uuid goto specific workspace and collection and copy the uuid part from url:

Note: you can also get UUID by clicking collection and clicking info panel on the right side

Now in your collection

Rename all requests as:

get user details [Regression][Smoke][Somethingelse]
get account details [Regression]

Then Create a new request called initial request and keep it as the first request in your collection:

url: https://api.getpostman.com/collections/8xxxxtheuuidyoucopied

authorization: apikey-header : key: X-Api-Key and value: yourapikey

test-script :

pm.environment.unset("requestToRun")
reqeustlist = pm.response.json().collection.item.map((a) => a.name)
requestToRun = reqeustlist.filter((a) => a.includes(pm.environment.get("tag")))
let val = requestToRun.pop()
pm.environment.set("requestToRun", requestToRun)
val ? postman.setNextRequest(val) : postman.setNextRequest(null)

Now set the envirnoment variable as what you want to look for eg: run script that contains text “Regression” then set pm.environment.set("tag","Regression")

Now in your collection-pre-request add:

if (pm.info.requestName !== "initial request") {
    let requestToRun = pm.environment.get("requestToRun")
    let val = requestToRun.pop()
    pm.environment.set("requestToRun", requestToRun)
    val ? postman.setNextRequest(val) : postman.setNextRequest(null)
}

Output:

Ran only reqeusts that has “Copy” in its name

Example collection:

https://www.getpostman.com/collections/73e771fe61f7781f8598 , you can click ctrl+o and choose link to import this collection

Note: In newman you can pass the environment variable as “ — env-var tag=Regression”
