  1. Interviewer: What are the common HTTP Request methods? HTTP defines a set of request methods to indicate the desired action to be performed. · GET: retrieve data. · HEAD: identical to GET request, but without the response body. · POST: submit an entity to the specified resource. · PUT: modify data with the request payload. · DELETE: delete the specified resource. · CONNECT: establish a network connection to a web server. · OPTIONS: find out the HTTP methods and other options supported. · TRACE: performs a message loop-back test. · PATCH: apply partial modifications to a resource. Sure, here are some interview questions on API testing for manual testers, along with some sample answers: Question: What is API testing? Answer: API testing is the process of testing an application programming interface (API) to ensure that it meets its requirements. APIs are used to communicate between different software components, and they are essential for the smooth functioning of many modern applications. API testing can be performed manually or automatically, and it typically involves sending requests to the API and validating the responses. Question: What are the different types of API testing? Answer: There are many different types of API testing, but some of the most common include: Functional testing: This type of testing ensures that the API meets its functional requirements. This includes testing the API's ability to perform specific tasks, such as creating, retrieving, updating, and deleting data. Security testing: This type of testing ensures that the API is secure and that it cannot be easily exploited by attackers. This includes testing for vulnerabilities such as SQL injection and cross-site scripting.

  2. Performance testing: This type of testing ensures that the API can handle the expected load. This includes testing the API's response time and its ability to handle multiple concurrent requests. Stress testing: This type of testing pushes the API to its limits to see how it performs under heavy load. This can help to identify any potential performance bottlenecks. Question: What are the benefits of API testing? Answer: API testing can provide many benefits, including: Increased confidence in the quality of the API Identification of potential defects early in the development process Reduced risk of security vulnerabilities Improved performance Increased customer satisfaction Question: What are the challenges of API testing? Answer: Some of the challenges of API testing include: The complexity of APIs The lack of documentation The need for specialized tools The difficulty of reproducing errors Question: What are the different tools that can be used for API testing? Answer: There are many different tools that can be used for API testing, including: Postman SoapUI JMeter SoapTest SoapUI Pro Question: How do you write API test cases? Answer: API test cases can be written using a variety of techniques, but some common steps include:

  3. 1. Identifying the API's requirements 2. Determining the different types of tests that need to be performed 3. Creating test cases that specify the inputs, expected outputs, and pass/fail criteria for each test 4. Documenting the test cases Question: How do you verify the results of API testing? Answer: The results of API testing can be verified by comparing the actual outputs to the expected outputs. This can be done manually or using automated tools. Question: What are some common API testing mistakes? Answer: Some common API testing mistakes include: Not testing the API thoroughly Not using the correct tools Not documenting the test cases Not verifying the results of the tests Question: What are the best practices for API testing? Answer: Some best practices for API testing include: Testing the API thoroughly Using the correct tools Documenting the test cases Verifying the results of the tests Using a variety of testing techniques Collaborating with developers Question: What is the future of API testing? Answer: The future of API testing is bright. As APIs become more complex and critical, the need for effective API testing will only grow. In the future, API testing will likely become more automated and integrated with other testing processes.
