Why Postman supports non-functional testing - Quick Recap

Recall & Review

beginner

What is non-functional testing?

Non-functional testing checks how well a system works, like its speed, reliability, and security, rather than what it does.

beginner

Why can Postman be used for non-functional testing?

Postman can test performance, security, and reliability of APIs by sending requests and checking response times, status codes, and data.

How does Postman measure API performance?

Postman records response time for each API request, helping testers see if the API is fast enough under different conditions.

intermediate

What role do assertions play in Postman for non-functional testing?

Assertions check if API responses meet expected conditions like response time limits or correct status codes, ensuring quality beyond functionality.

intermediate

Can Postman test API security? How?

Yes, Postman can test security by sending requests with different authentication tokens and checking if unauthorized access is blocked.

What type of testing focuses on how well a system performs rather than what it does?

A Non-functional testing

B Functional testing

C Unit testing

D Integration testing

Non-functional testing checks qualities like speed and reliability, not specific functions.

Which Postman feature helps measure API response time?

A Response time metrics

B Code editor

C Environment variables

D Mock servers

Postman shows response time for each request, useful for performance testing.

How does Postman help test API security?

A By creating UI tests

B By editing API code

C By sending requests with different authentication tokens

D By generating reports only

Testing with various tokens checks if unauthorized access is prevented.

What is an assertion in Postman used for?

A To design UI layouts

B To write API documentation

C To create new API endpoints

D To verify API response meets expected conditions

Assertions check if responses are correct, including status and timing.

Which of these is NOT a non-functional testing aspect Postman supports?

A Performance

B User interface design

C Security

D Reliability

Postman tests APIs, not user interface design.

Explain why Postman is suitable for non-functional testing of APIs.

Think about what qualities besides functionality Postman can check.

Describe how you would use Postman to test API performance and security.

Consider sending different requests and checking their results.
