What is functional and non functional testing with examples?

What is functional and non functional testing with examples?

Functional testing has a goal to validate software actions whereas Non Functional testing has a goal to validate the performance of the software. A Functional Testing example is to check the login functionality whereas a Non Functional testing example is to check the dashboard should load in 2 seconds.

What is non functional testing in black box testing?

Non-functional testing – This type of black box testing is not related to testing of specific functionality, but non-functional requirements such as performance, scalability, usability.

What types of errors are not covered by black box testing and can be uncovered by white box testing?

5 . What types of errors are missed by black-box testing and can be uncovered by white-box testing?

  • behavioral errors.
  • logic errors.
  • performance errors.
  • typographical errors.
  • b and d.

What is blackbox and whitebox testing?

Black box testing is considered high-level testing, which means that its main goal is to test functionalities from the behavioral point of view. White box testing, also known as clear box testing, happens when you have insight into the code and/or general knowledge about the architecture of the software in question.

What’s the difference between functional testing and nonfunctional testing?

The difference between functional and nonfunctional testing is what they test. Functional testing ensures that functions and features of the application work properly. Nonfunctional testing examines other aspects of how well the application works. Functional testing tests the functionality of an app.

What are nonfunctional test cases?

Non-functional testing checks all the aspects not covered in functional tests. It includes the performance, usability, scalability, and reliability of the software. We conduct non-functional testing to make sure that the interests of the end-user are respected.

What is non functional testing types with example?

The most common ones are:

  • Performance Tests.
  • Load Tests.
  • Stress Tests.
  • Volume Tests.
  • Security Tests.
  • Upgrade & Installation Tests.
  • Recovery Tests.

What types of errors are not done by black box testing and?

Q. What types of errors are missed by black-box testing and can be uncovered by whitebox testing?
B. Logic errors
C. Performance errors
D. Typographical errors
Answer» d. Typographical errors

What is functional testing in software testing with examples?

Functional testing is the process through which QAs determine if a piece of software is acting in accordance with pre-determined requirements. It uses black-box testing techniques, in which the tester has no knowledge of the internal system logic.

What is the difference between functional and nonfunctional?

What are those, and how are they different? Simply put, the difference is that non-functional requirements describe how the system works, while functional requirements describe what the system should do. One could also think of non-functional requirements as quality attributes for of a system.

Is system testing functional or nonfunctional?

Different Types of Functional testing are Unit testing, Integration testing, Smoke testing, Usability testing, User acceptance testing, System testing, Regression testing.

How do you test functional and nonfunctional requirements?

Functional testing is done based on the business requirement. Non- functional testing is done based on the customer expectation and Performance requirement. It tests whether the actual result is working according to the expected result. It checks the response time, and speed of the software under specific conditions.

What is the difference between white box testing and Blackbox testing?

Its counterpart, Blackbox testing, involves testing from an external or end-user type perspective. On the other hand, White box testing in software engineering is based on the inner workings of an application and revolves around internal testing. The term “WhiteBox” was used because of the see-through box concept.

What is the time consumption in black box testing?

Time consumption in Black Box testing depends upon the availability of the functional specifications. White Box testing takes a long time to design test cases due to lengthy code. Test cases designing can be done in a short time period.

What is black box testing and software development life cycle?

Black Box Testing and Software Development Life Cycle (SDLC) Black box testing has its own life cycle called Software Testing Life Cycle (STLC) and it is relative to every stage of Software Development Life Cycle of Software Engineering. Requirement – This is the initial stage of SDLC and in this stage, a requirement is gathered.

What are the main tradeoffs between black box gray box and white-box?

The main tradeoffs between black-box, gray-box and white-box penetration testing are the accuracy of the test and its speed, efficiency and coverage. The purpose of penetration testing is to identify and patch the vulnerabilities that would be exploited by an attacker.
