Absolute xpath starts from the root element while relative xpath starts from any element in the DOM.

• Absolute xpath starts with a single forward slash (/) and always starts from the root element of the page.

• Relative xpath does not start with a forward slash and can start from any element in the DOM.

• Absolute xpath is more brittle and prone to breaking if the structure of the page changes.

• Relative xpath is more flexible a...read more

In API testing, we test the functionality, performance, security, and reliability of the API.

• Functionality testing to ensure the API works as expected

• Performance testing to check the response time and throughput

• Security testing to identify vulnerabilities and ensure data protection

• Reliability testing to verify the API's stability under different conditions

Payload is the data transmitted in an API request, while request body is a part of the payload containing the actual data being sent.

• Payload includes all data sent in an API request, such as headers, parameters, and request body

• Request body specifically refers to the part of the payload that contains the actual data being sent

• In API testing, it is important to validate both the payload and request body for accuracy

Test case for integration scenario of API testing with main status codes in responses

• Test case: Verify that the API response includes the expected data fields and values after integrating with another API

• Main status codes: 200 (OK), 201 (Created), 400 (Bad Request), 401 (Unauthorized), 404 (Not Found), 500 (Internal Server Error)

Java program to reverse a string

• Create a char array from the input string
