API Testing

API Testing is a type of software testing that validates Application Programming Interfaces (APIs) to ensure they meet expectations for functionality, reliability, performance, and security. API testing can be conducted using both automated and manual methods. The purpose of API testing is to validate that the API meets its functional and non-functional requirements, and that the API is working as expected. Some of the common objectives of API testing include verifying data accuracy, validating response time, and ensuring the API is secure.

API Testing Techniques

• Functional Testing: This type of testing ensures that the API functions as expected. This includes testing the API endpoints, parameters, and response codes.
• Security Testing: This type of testing ensures the API is secure and not vulnerable to attack. This includes testing authorization, authentication, encryption, and other security measures.
• Performance Testing: This type of testing ensures the API meets performance requirements, such as response time and throughput.
• Load Testing: This type of testing ensures the API can handle a high volume of requests.
• Stress Testing: This type of testing ensures the API can handle extreme loads.
• Stress Testing: This type of testing ensures the API can handle extreme loads.
• Compatibility Testing: This type of testing ensures the API is compatible with other systems and platforms.

Benefits of API Testing

• API testing allows for faster development cycles and shorter release cycles.
• API testing is less costly than GUI testing.
• API testing is more reliable and more accurate than GUI testing.
• API testing allows for better integration with other systems and platforms.
• API testing is more flexible and can be automated.
• API testing can be used to test for security vulnerabilities.
