Dynamic values in Rest API using JMeter

Question

I have payload POST call:

{  

   "tenantName":"loki",

 "owner":
 {
    "country": "india",
    "firstName": "raj",
    "lastName": "kumar",
    "locale": "in",
    "organization": "softwareag",
    "phone": "9789155778",
    "title": "mr",
    "userName": "raraj@softwareag.com",
    "email": "raraj@softwareag.com",
    "password":"V2VsY29tZUAxMjM0"
 },
  "products": [
    "cumulocity",
    "b2b"
  ]
}

In that payload, the tenant name is unique, How to pass different values for each post call?

You can use __RandomString to randomize name, for example 5 lower case letters:

${__RandomString(5,abcdefghijklmnopqrstuvwxyz,)}

RandomString function returns a random String of length using characters in chars to use

Or load name values from CSV Data set config

@surya great, you can accept the answer if it helped, see https://meta.stackexchange.com/questions/5234/how-does-accepting-an-answer-work – Ori Marko Dec 18 '19 at 07:35
is there any otherway, using script? – surya Dec 18 '19 at 08:50
@surya yes see https://stackoverflow.com/questions/8138164/groovy-generate-random-string-from-given-character-set/8138604#8138604 – Ori Marko Dec 18 '19 at 09:13
can we save that tenant name variable, because it picks random value.In another api payload, i need to pass the same value which the tenant name picks? – surya Dec 18 '19 at 13:58
@surya yes, add the variable name in the after the comma (last parameter) `${__RandomString(5,abcdefghijklmnopqrstuvwxyz,YOURVARIABLENAME)}` – Ori Marko Dec 18 '19 at 14:00
can we use that saved variable in path...? – surya Dec 19 '19 at 09:47
@surya yes using `${YOURVARIABLENAME}` – Ori Marko Dec 19 '19 at 09:48

You can use __groovy() function in order to call RandomStringUtils.randomAlphabetic() method like:

${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(4),)}

replace 4 with the number of your choice to make the random string shorter or longer

The function can be inlined directly into your request body

{
  "tenantName": "${__groovy(org.apache.commons.lang3.RandomStringUtils.randomAlphabetic(4),)}",
  "owner": {
    "country": "india",
    "firstName": "raj",
    "lastName": "kumar",
    "locale": "in",
    "organization": "softwareag",
    "phone": "9789155778",
    "title": "mr",
    "userName": "raraj@softwareag.com",
    "email": "raraj@softwareag.com",
    "password": "V2VsY29tZUAxMjM0"
  },
  "products": [
    "cumulocity",
    "b2b"
  ]
}
