💡 Hint

Common Mistakes

Using a wrong status code like 201 or 404.

Forgetting to put the status code as a number.

The status code 200 means the request was successful. We use pm.response.to.have.status(200) to check this.

2fill in blank

medium

Complete the code to assert the JSON response has a property 'userId' equal to 1.

Postman

pm.test("User ID is 1", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.[1]).to.eql(1);
});

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using incorrect property names like 'id' or 'userid'.

Not matching the case exactly.

The JSON response property is named userId. We access it as jsonData.userId to check its value.

Fix the error in the code to assert the response time is less than 500 ms.

Postman

pm.test("Response time is less than 500ms", function () {
    pm.expect(pm.response.[1]).to.be.below(500);
});

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using incorrect property names like 'time' or 'duration'.

Confusing response time with other response properties.

The correct property for response time in Postman is pm.response.responseTime. Using this allows the assertion to check the response time correctly.

4fill in blank

hard

Fill both blanks to assert the JSON response array length is greater than 3.

Postman

pm.test("Array length is greater than 3", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.[1].[2]).to.be.above(3);
});

Drag options to blanks, or click blank then click option'

Aitems

Blength

Ccount

Dsize

💡 Hint

Common Mistakes

Using wrong property names like 'count' or 'size'.

Trying to check length on a non-array property.

The JSON response has an array property named items. To get its length, we use items.length. Then we check if it is above 3.

5fill in blank

hard

Fill all three blanks to assert the response header 'Content-Type' includes 'json'.

Postman

pm.test("Content-Type header includes json", function () {
    var contentType = pm.response.headers.get('[1]');
    pm.expect(contentType.[2]('[3]')).to.be.true;
});

Drag options to blanks, or click blank then click option'

AContent-Type

Bincludes

Cjson

Dcontent-type

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong header name like 'content-type' (wrong case).

Using wrong string method like 'contains' instead of 'includes'.

Checking for wrong substring.

We get the header named Content-Type (case sensitive). Then we check if it includes the string json using the includes method.
