RESTful Web API Design with Node.js (Video 14)

This video tutorial covers acceptance testing for APIs using Postman. It explains the importance of acceptance tests in ensuring API changes do not break existing applications. The tutorial guides viewers through installing Postman and its Interceptor extension, using the Postman interface, creating and testing API requests, handling errors, and running tests. Advanced testing techniques, such as using environment variables and automating test cases, are also discussed.

What is the primary purpose of acceptance testing in API development?

• To reduce the cost of API development

• To enhance the user interface of the API

• To improve the speed of the API

• To ensure the API meets specified requirements

What is the role of Postman Interceptor?

• To provide additional security features

• To increase the speed of API requests

• To allow Postman to send cookies in API requests

• To enhance Postman's user interface

Which tab in Postman shows the history of requests sent?

• Dashboard tab

• Requests tab

• History tab

• Collections tab

What is the first step in creating a GET request in Postman?

• Select the POST method

• Open the Headers tab

• Run the application to get a valid URL

• Add a cookie header

Why did the POST request initially fail in the video?

• The URL was incorrect

• The request body was not parsed

• The server was down

• The method was set to GET instead of POST

What should be done to ensure the request body is parsed correctly?

• Add a content type header

• Remove all headers

• Change the request method to GET

• Use a different API endpoint

What is the purpose of using environment variables in Postman?

• To manage different environments easily

• To reduce the size of requests

• To automate the testing process

• To store API keys securely

How can you pass data from one request to another in Postman?

• By using session variables

• By using environment variables

• By using global variables

• By using local variables

What is the benefit of running an entire collection in Postman's test runner?

• It provides detailed error logs

• It reduces the number of requests sent

• It allows for automated cleanup after tests

• It speeds up the testing process

What type of testing will be covered in the next video?

• Integration testing

• Load testing

• Security testing

• Unit testing
