Asserting entire response body in post man

Question

I recently started working on spring boot projects. I am looking for a way to assert the entire response of my API. The intention of this is to reduce the testing time taken for the API.

Found A few solutions mentioned below, but nothing helped me resolve the issue.

pm.test("Body matches string", function () {
    pm.expect(pm.response.text()).to.include("string_you_want_to_search");
});


pm.test("Body is correct", function () {
    pm.response.to.have.body("response_body_string");
});

When I put the entire response body as an argument, I get the below errors.

Unclosed String

Do you *need* to assert against a string? Your test is checking JSON but as a string, It doesn’t seem like a good approach. Why tag the question with JSON? — Danny Dainton, Jan 02 '18 at 08:30

If you want to use the same type of quotes you defined the string with inside it, you have to escape them:

'string with "quotes"'
"string with 'quotes'"
'string with \'quotes\''
"string with \"quotes\""

You probably want to put your json in single quotes as they are not allowed by json itself.

As *Postman* uses *JS* in *Tests/Pre-request Scripts*, you also can use a *grave accent*. Consider: `\`string with both 'single quotes' and "double quotes\`` – n-verbitsky Apr 14 '20 at 18:34

You could try setting the response as a variable and then assert against that?

var jsonData = pm.response.json()

pm.environment.set('responseData', JSON.stringify(jsonData))

From here you can get the data JSON.parse(pm.enviroment.get('responseData')) and then use this within any test to assert against all of the values.

pm.test("Body is correct", () => {
    var jsonData = pm.response.json()
    pm.expect(jsonData).to.deep.equal(JSON.parse(pm.environment.get('responseData')))
})

My reasoning is that you’re trying to assert against JSON anyway but doing as a plain text string.

Or you could assert against the values separately like this:

pm.test("Body is correct", () => {
    var jsonData = pm.response.json()
    pm.expect(jsonData[0].employeeName).to.equal("tushar")
    pm.expect(jsonData[0].phNum).to.equal(10101010)
})

Depending on the JSON structure you may not need to access an array of data and the [0] can be dropped.
