Frequently Asked Questions

What is the primary role of a Non Functional Tester?

The primary role of a Non Functional Tester is to evaluate the non-functional aspects of software applications, such as performance, usability, reliability, and security. This involves creating and executing test cases that focus on how the application behaves under various conditions rather than checking its functionalities. Non Functional Testers work to ensure that the software meets specific standards and user expectations beyond just functional requirements.

What key skills are required for a Non Functional Tester?

A Non Functional Tester should possess a strong understanding of testing methodologies and tools, particularly those related to performance and load testing. Key skills include analytical thinking, attention to detail, and proficiency in scripting languages for automation testing. Familiarity with performance testing tools like JMeter or LoadRunner, as well as knowledge of database management and server configurations, are also essential for effectively identifying and resolving non-functional issues.

How does Non Functional Testing differ from Functional Testing?

Non Functional Testing focuses on the attributes of the software that do not pertain to specific functionalities, such as performance, scalability, and security, while Functional Testing verifies that the software behaves as expected in terms of functionality based on requirements. Essentially, Non Functional Testing assesses how well the application performs under certain conditions, whereas Functional Testing checks if the application works correctly according to its defined functions.

What are some common types of Non Functional Testing?

Common types of Non Functional Testing include performance testing, load testing, stress testing, usability testing, security testing, and compatibility testing. Performance testing assesses how the application performs under various conditions, load testing evaluates its behavior under expected loads, and stress testing determines its limits under extreme conditions. Usability testing focuses on the user experience, while security testing checks for vulnerabilities and compliance with security standards.

What tools are commonly used in Non Functional Testing?

There are various tools commonly used in Non Functional Testing, including Apache JMeter, LoadRunner, Gatling, and NeoLoad for performance and load testing.
