Postman – test API

Postman learning portal https://learning.getpostman.com/docs/postman/scripts/test_scripts/

Global variable

postman.setGlobalVariable("foobar", "1"); 
tests["global var foobar = true"] = globals.foobar == true; 
postman.setGlobalVariable("bar", "0"); 
tests["global var bar = false"] = globals.bar == false;

Envirement variable

postman.setEnvironmentVariable("foo", "bar");
tests["environment var foo = bar"] = environment.foo === "bar";

Change String to Number

parseInt(environment.RESPONSE_TIME)

Get HTML code

Use CheariosJs

Parse JSON object into variable

var responseData = JSON.parse(responseBody);

Iterate throw JSON array
Save Json Object into envirement variable – use JSON.stringify()

for (i = 0; i < responseData.length; i++) { 
   console.log( "response["+i+"]:"+ responseData[i].Symbol + ", id: "+  responseData[i].Id )
   postman.setEnvironmentVariable("Currency_"+responseData[i].Symbol , 
JSON.stringify(responseData[i]) );
 }

Test Values

Check if values are included in response

pm.test("response should be okay to process", function () { 
  pm.response.to.not.be.error; 
  pm.response.to.have.jsonBody("User"); 
  pm.response.to.have.jsonBody("UserRoles"); 
 });

Create Random Number

var rnd = Math.floor(Math.random() * 1000);
