Tests tab and pm.test() in Postman - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the Tests tab in Postman?

The Tests tab in Postman is used to write scripts that run after a request is sent. These scripts check if the response meets expected conditions, helping verify the API works correctly.

What does the pm.test() function do in Postman?

The pm.test() function defines a test with a name and a function containing assertions. It runs the test and reports if it passed or failed based on the assertions inside.

Write a simple pm.test() example that checks if the response status code is 200.

pm.test("Status code is 200", function () { pm.response.to.have.status(200); });

Why is it important to name your tests clearly in pm.test()?

Clear test names help you understand what each test checks when you see the test results. It makes debugging easier if a test fails.

How can you check if a JSON response contains a specific key using pm.test()?

Use pm.test() with pm.response.json() to parse the response and then check the key. Example:
pm.test("Response has userId", function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData).to.have.property('userId');
});

What does pm.test() require as arguments?

A Only a function with assertions

B Only a test name

C A test name and a function with assertions

D A request URL and headers

pm.test() needs a descriptive test name and a function that contains the assertions to check the response.

Where do you write pm.test() scripts in Postman?

A In the Tests tab after sending a request

B In the Body tab before sending a request

C In the Headers tab

D In the Authorization tab

The Tests tab is where you write scripts that run after the request completes.

Which assertion checks if the response status code is 200?

A pm.response.to.have.status(200);

B pm.response.status(200);

C pm.response.code(200);

D pm.response.check(200);

The correct syntax to assert status code 200 is pm.response.to.have.status(200);

What happens if an assertion inside pm.test() fails?

A The test passes anyway

B The request is resent automatically

C Postman stops running all tests

D The test fails and is reported in the test results

If an assertion fails, the test is marked as failed and shown in the test results.

How do you access the JSON response body inside pm.test()?

A Using pm.response.text()

B Using pm.response.json()

C Using pm.response.body()

D Using pm.request.json()

pm.response.json() parses the response body as JSON for assertions.

Explain how to write a test in Postman using pm.test() to check if the response status code is 200.

Think about naming the test and the assertion syntax.

Describe the role of the Tests tab in Postman and how pm.test() fits into it.

Consider when tests run and what they do.
