Understanding HTTP Request Methods

Which HTTP request method is typically used to update an existing resource on a server?

A PUT

B POST

C DELETE

D GET

💡 Hint

Think about which method replaces the entire resource with new data.

The PUT method is used to update or replace an existing resource entirely. POST is usually for creating new resources, GET retrieves data, and DELETE removes resources.

HTTP Status Code Meaning

What is the meaning of the HTTP status code 404?

A Resource not found on the server

B Request succeeded and resource was created

C Server encountered an internal error

D Request was unauthorized

💡 Hint

It is a common error when a webpage is missing.

404 means the requested resource could not be found on the server. 201 means created, 500 means internal server error, and 401 means unauthorized.

Validating HTTP Response Status in Tests

Which assertion correctly checks that an HTTP response status code is 200 in a test?

Testing Fundamentals

response = client.get('/api/data')

A assert response.status_code = 200

B assert response.status == '200 OK'

C assert response.status_code == 200

D assert response.code == 200

💡 Hint

Check the attribute name and use the correct comparison operator.

The correct attribute is 'status_code' and the comparison operator is '=='. Option C uses a string which may not be standard, C uses a wrong attribute, and D uses assignment '=' instead of comparison '=='.

Identifying the Cause of a 405 Error

A test sends a POST request to an endpoint but receives a 405 Method Not Allowed error. What is the most likely cause?

A The request body is missing

B The server is down

C The request URL is incorrect

D The endpoint does not support the POST method

💡 Hint

405 means the method is not allowed on that URL.

405 status code means the HTTP method used is not supported by the endpoint. Server down would cause no response or 5xx errors, incorrect URL usually 404, and missing body usually 400 or 422.

Choosing the Best Test Framework Feature for HTTP Status Validation

In an automated API test suite, which feature of a test framework best helps to verify multiple HTTP status codes efficiently?

A Writing separate test functions for each status code manually

B Using parameterized tests to run the same test with different expected status codes

C Ignoring status codes and only checking response body content

D Using print statements to manually check status codes during test runs

💡 Hint

Think about reducing repeated code and improving test coverage.

Parameterized tests allow running one test logic multiple times with different inputs and expected outputs, making it efficient to check various status codes. Writing separate tests is repetitive, ignoring status codes misses important checks, and print statements are not automated verification.
