Usecases of Random Number

to do

Using ${RANDOM.NUMBER}

`"steps":[{ "name": "mytest", "url": "/orders", "operation": "POST", "request": { "headers": { "Content-Type": "application/json;charset=UTF-8" }, "body": { "orders": [ { "orderId": "${RANDOM.NUMBER}", "amount": 5, "productName": "product1" }, { "orderId": "${RANDOM.NUMBER}", "amount": 10, "productName": "product2" } ] } },

  "assertions": {
    "status": 200

  }
}]`

after replacing RANDOM.NUMBER placeholders,we get the following request: request: { "headers" : { "Content-Type" : "application/json;charset=UTF-8" }, "body" : { "orders" : [ { "orderId" : "6432473468588586502", "amount" : 5, "productName" : "product1" }, { "orderId" : "6249704932535842532", "amount" : 10, "productName" : "product2" } ] } }

every instance of RANDOM.NUMBER is unique

Using ${RANDOM.NUMBER.FIXED}

sample step: ` { "name": "mytest", "url": "/orders", "operation": "POST", "request": { "headers": { "Content-Type": "application/json;charset=UTF-8" }, "body": { "orders": [ { "orderId": "${RANDOM.NUMBER.FIXED}", "amount": 5, "productName": "product1" }, { "orderId": "${RANDOM.NUMBER.FIXED}", "amount": 10, "productName": "product2" } ] } },

  "retry":{
    "max": 2,
    "delay": 500
  },

  "assertions": {
    "status": 200

  }
},`

after RANDOM.NUMBER.FIXED placeholder are replaced we get the following request:

request: { "headers" : { "Content-Type" : "application/json;charset=UTF-8" }, "body" : { "orders" : [ { "orderId" : "6598115625161692428", "amount" : 5, "productName" : "product1" }, { "orderId" : "6598115625161692428", "amount" : 10, "productName" : "product2" } ] } }

RANDOM.NUMBER.FIXED placeholders get the same random number value within the step

Using ${RANDOM.NUMBER:10}

we can limit random numbers' length. In this case random numbers length(digit count) would be 10.
