Why black box testing is called functional testing?
It takes into account functionality of the application only. It is also called functional testing. Tester is mainly concerned with the validation of the output rather than how the output is produced. Knowledge of programming or implementation logic ( of internal structure and working) is not required for testers.

What is the difference between black box testing and functional testing?
A type of black box testing that focuses on specific functions in the application. This includes sanity checks, integration testing, or system testing. Functional testing is performed by providing a certain input and checking if the output meets the software requirements and specifications.
What is meant by functional and non functional testing?
Functional requirements are the WHAT; nonfunctional requirements are the HOW. So, the testing of functional requirements is the verification that the software is executing actions as it should, while nonfunctional testing helps verify that customer expectations are being met.
What type of error are not covered by black box testing?
Logic errors not done by Black-Box Testing & can be uncovered by White-Box Testing.
Can a black box be used for functional testing?
This technique is not limited to test the functionalities only but can also be used for testing the non-functional requirements as well as the Performance, usability, etc. Black box testing technique does not require any knowledge of the internal system i.e. it does not require the knowledge of code to the tester.
What’s the difference between functional and non-functional 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. Regression testing – Regression Testing is done after code fixes, upgrades or any other system maintenance to check the new code has not affected the existing code.
When do you use a non functional requirement?
Non functional requirements specify how it needs to be tested. Functional testing is performed before the application goes live. Non functional requirements includes the maintenance testing, Documentation testing which are not required while execution is going on but one the application has gone live. It is known as functional requirement only.
What’s the purpose of functional testing in automation?
