Questions & Answers

Browse all 18 questions from the Developing a Baseline Test Suite from an API Specification study set below. Each question shows the correct answer — select a study format above to practice interactively.

1 What is the fastest way to bootstrap a test suite according to the text?

A Starting from scratch
B Using a pre-built test suite
C Starting from your API specification
D Writing individual tests manually

2 What does spec-first development mean in the context of APIs?

A The API code is written before the specification
B The API's contract is defined before the code is written
C The API specification is generated after the code is complete
D The API specification is only used for documentation

3 Why is it recommended to create a fork of a generated collection instead of modifying it directly?

A To make the original collection inaccessible
B To allow for test-specific modifications without affecting the source
C To speed up the generation process
D To prevent changes from being pulled from upstream

4 What HTTP status code indicates an authentication issue?

A 404 Not Found
B 400 Bad Request
C 200 OK
D 401 Unauthorized

5 If an endpoint returns a 404 Not Found error, what is a common cause related to variables?

A The {{baseUrl}} variable is missing or incorrect
B The {{apiKey}} variable is expired
C The {{userName}} variable has incorrect permissions
D The {{portNumber}} variable is not defined

6 What does a 400 Bad Request error typically signify?

A The server is unreachable
B Required query parameters are missing or malformed
C The authentication token is invalid
D The API endpoint does not exist

7 What is the recommended way to store values like API keys and base URLs for maintainability?

A Hardcoding them directly into each request
B Storing them in a separate text file
C Using environment variables in Postman
D Embedding them in the API specification

8 How are variables referenced within Postman requests when using environments?

A Using single curly braces, e.g., {variableName}
B Using double curly braces, e.g., {{variableName}}
C Using square brackets, e.g., [variableName]
D Using the '@' symbol, e.g., @variableName

9 What is a benefit of using variables and environments for test suites?

A It increases the number of API calls
B It makes it easy to switch between different environments (dev, staging, prod)
C It reduces the need for API documentation
D It automatically generates test cases

10 What does the 'Connection refused' error suggest?

A An issue with the API logic
B The API server might be unreachable
C The request payload is too large
D A problem with the test environment setup

11 Which of the following is NOT mentioned as a common API specification format?

A OpenAPI
B Swagger
C RAML
D GraphQL Schema Definition Language (SDL)

12 What is the purpose of setting authentication at the collection level?

A To apply different authentication to each request
B To inherit authentication settings for all requests within the collection
C To bypass authentication for all requests
D To enable basic authentication only

13 What should you check if the {{baseUrl}} variable is not set correctly?

A The Authorization tab in Postman
B The active environment in Postman
C The request headers
D The response body

14 What are common culprits for a 400 Bad Request when dealing with query parameters?

A Missing or malformed countryName or airportCode
B Expired authentication token
C Incorrect HTTP method
D Unreachable server

15 What is the 'Meet Agent Mode' mentioned in the text?

A A debugging tool
B A self-study course

A $50
B $25
C $75
D Free

17 What chapter is 'Developing a Baseline Test Suite' presented as?

A Chapter 1
B Chapter 2
C Chapter 3
D Chapter 4

18 What does the text suggest doing once your environment is configured and endpoints are returning 200s?

A Immediately start writing assertions
B Send a message to the dev team about the test suite's readiness
C Update the API specification
D Deploy the API to production
