I have a postman collection which I have managed to run from Jenkins using Newman.

I have a groovy pipeline in which I install the dependencies included in my package.json (Newman in this case). From here, I can run a shell script to call the collection:

  stage( 'DEV: Install Dependencies' ) {
      sh 'npm install -g newman'
      sh 'npm install'

  stage( 'Running API Tests') {
  sh 'bash ./scripts_uat/create-new-product.sh'

create-new-product.sh calls the parameterized create-new-product.json which uses a number of global vars held in a file global-vars.json, a snippet of which below:

    "body": {
                "mode": "raw",
                "raw": "{\n  \"dept\": \"{{department}}\",\n  \"prodId\": \". 

I am unclear how I can expose the global vars within Jenkins such that they can be passed as Choice Params from within Jenkins.

A snippet of the global-vars.json:

"_": {
"postman_variable_scope": "globals",
"postman_exported_at": "2020-02-27T14:37:33.884Z",
"postman_exported_using": "Newman/4.5.7"
"id": "3147c1d3-e108-4689-ad7b-0cc719647103",
"name": "globals",
"values": [
  "type": "any",
  "value": "8293004039",
  "key": "product_id"
  },// more vars

How would I expose {{productID}} such that it can override the value within global-vars.json?

Can anyone give me some pointers? There is probably a better way of doing this.

This gives the entire command-line options for Newman

so you can use --global-var "<global-variable-name>=<global-variable-value>" to override global variable values.

As we know the precedence of variables is as follows:

(Precedence increase top to button , meaning local> has more precedence than global)

enter image description here

so passing an environmental variable as : --env-var "<environment-variable-name>=<environment-variable-value>"

will also override the value

  • thank you, that makes sense
