Status codes are numerical codes that indicate the status of a HTTP request/response.

• Status codes are grouped into 5 categories: informational, success, redirection, client error, and server error.

• Informational codes (1xx) indicate that the request was received and understood.

• Success codes (2xx) indicate that the request was successfully received, understood, and accepted.

• Redirection codes (3xx) indicate that further action needs to be taken in order to complete the request.

• C...read more

A defect in manual testing refers to an issue or flaw in the software application that is identified during the testing process.

• Defects can include functionality issues, design flaws, performance problems, or security vulnerabilities.
