Hi Team ,
Can anyone please help me here
I have test now it will get yesterday data when ever we run .
Now I want If I run my test on Monday it should get Friday data ,
Every week Saturday and Sunday are holidays no data will be available , I want to skip weekends
Present Pre-Request Script
const moment = require(‘moment’);
pm.collectionVariables.set(“data_date”, moment().subtract(1, ‘day’).format(“YYYY-MM-DD”));
So the tests are running based on the data_date is it?
you can use getDate() method to get the date values in numbers.
You can try the below snippet:
const moment = require('moment');
var myDate = new Date();
console.log(myDate);
//console.log(myDate.getDay());
if(myDate.getDay() == 6)
{
console.log("It's Saturday!!");
}
if(myDate.getDay() == 0)
{
console.log("It's Sunday!!");
}
if(myDate.getDay() == 1)
{
console.log("It's Monday!!");
pm.collectionVariables.set("data_date", moment().subtract(3, 'day').format("YYYY-MM-DD"));
}
else{
console.log("It's Weekday!!");
pm.collectionVariables.set("data_date", moment().subtract(1, 'day').format("YYYY-MM-DD"));
}
Saturday and Sunday can be clubbed under same loop, incase if you want to run Friday data on Saturday you can add one more line under the first if block.
If you are looking for something else, please provide us more details 
Thank you @bpricilla
yes , tests are running based on the data_date
I have used below snippet
const moment = require('moment');
let today = moment().day();
if(today == 0 || today == 1){
pm.environment.set("previous_tradedate",moment().subtract(6,'days').day(5).format("YYYY-MM-DD"));
}
else {
pm.environment.set("previous_tradedate",moment().day(today - 1).format("YYYY-MM-DD"));
}
It looks like you both have things covered here but I wanted to offer a suggestion 
When I try and parse days of the week as numbers in my head, it kinda goes 
maybe having them as actual days might help with the readability here?
let moment = require('moment'),
today = moment().format('dddd');
if(today === 'Saturday' || today === 'Sunday') {
// Do something
}
else {
// Do something else
}
