• It has a modular structure with reusable functions and libraries.

• It generates detailed HTML reports with screenshots and logs.

• It supports parallel execution and integration with CI/CD tool...read more

Defect lifecycle is the process of identifying, reporting, fixing, and verifying defects in software.

• Defect is identified by testers during testing

• Defect is reported to development team

• Development team fixes the defect

• Fixed defect is verified by testers

• If defect is not fixed, it goes back to development team

• If defect is fixed, it is closed

I have used Postman for API testing.

• Postman is a popular tool for API testing and has a user-friendly interface.

• It allows us to send requests, view responses, and test different scenarios.

• We can also create collections of requests and run them in a sequence.

• Postman also has features like environment variables and test scripts.
