💡 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 assert this.

2fill in blank

medium

Complete the code to assert that the JSON response has a key named 'name'.

Postman

pm.test("Response has 'name' key", function () { pm.expect(pm.response.json()).to.have.property([1]); });

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

A"age"

B"name"

C"email"

D"status"

💡 Hint

Common Mistakes

Using a wrong key name.

Not using quotes around the key.

We check if the JSON response has the key "name" using to.have.property("name").

Fix the error in the code to assert that the 'age' value equals 30.

Postman

pm.test("Age is 30", function () { pm.expect(pm.response.json().age).to.be.[1](30); });

💡 Hint

Common Mistakes

Using 'equals' or 'eq' which cause errors.

Misspelling the method name.

The correct Chai assertion method is equal to check value equality.

4fill in blank

hard

Fill both blanks to assert that the response JSON array 'users' has length 5.

Postman

pm.test("Users array length is 5", function () { pm.expect(pm.response.json().[1]).to.have.length[2](5); });

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

BlengthOf

Clength

DuserList

💡 Hint

Common Mistakes

Using wrong key name like 'userList'.

Using 'length' instead of 'lengthOf' in assertion.

We access the 'users' array and use lengthOf to check its length.

5fill in blank

hard

Fill all three blanks to assert that the 'status' key in JSON equals 'success' and is a string.

Postman

pm.test("Status is success string", function () { pm.expect(pm.response.json().[1]).to.be.a([2]).and.to.equal([3]); });

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

Astatus

B"string"

C"success"

Dresult

💡 Hint

Common Mistakes

Using wrong key name like 'result'.

Not quoting the type or value strings.

We check the 'status' key, assert its type is 'string', and its value equals 'success'.
