Postman Asserts | provide a clean way to organize tests

If you want use Tests inside Postman, you must always write assertions like this:

pm.test('Response should have JSON Body', function () {
    pm.response.to.have.jsonBody();
});

// or
tests["Response Data is Valid"] = tv4.validate(pm.response.json(), schema);

It will be better if we can use Reusable functions inside Postman. It's more flexible...

Writing tests within Postman Reusable functions

To have Assertions inside your Collection, you need to do next steps:

• Save content of pm_asserts.min.js script as a global variable
• In the Postman Test scripts - eval postman_asserts global variable
• Call Asserts functions by functions' name

Setting up Assertions Script to Postman Globals

To set up Assertions - just download Collection and make API call with it. This Request will get Script content and set up Global variable into Postman Environment.

Using Assertions inside Postman Tests

Into Tests window call Assertions after eval() Postman Globals variable, which contains Script body.

eval(globals.postman_asserts);

const schema = {
    "type": "object",
    "required": ['args', 'headers']
};

isJsonResponse();
isResponseStatus(200);
validateJsonSchema(schema);
