Up till now, you must have seen separate articles for Functional Testing and Non-Functional testing. In any case, in today’s article we will see the real distinction between Functional Testing and Non-Functional Testing.

1. Difference Between Functional Testing and Non-
Functional Testing
What do you mean by non functional testing?
The non functional Testing is the kind of testing done
against the non functional needs. The vast majority of the
criteria are not considered in functional testing so it is
utilized to check the availability of a system

2. Non Fuctional Testing
Non functional testing affects client and client satisfaction
with the product. Non functional testing is expected to be
told in a testable manner “the software should be fast” or
“the software ought to be easy to operate” which is not
testable.

3. Cont.....
The testing of software properties which are not identified with
a particular function or client activity like execution,
adaptability, security or behavior pattern of application under
specific limitations.

4. Non Functional Testing Types

Load testing

Reliability testing

Performance testing

Security testing

Volume testing

Installation testing

Localization testing and internationalization testing

Recovery testing

Stress testing and many more……

5. What do you mean by functional testing?

6. Five stages required to remember in case of Functional
testing:

Arrangement of test data in light of the requirements of the
function.

Business necessities are the inputs to functional testing.

In light of functional specifications, discover of output of the
functions.

Executing the test cases.

Watch the actual and expected results.

7. Following types of testing need to be covered
under functional testing

Sanity testing

System testing

Integration testing

Smoke testing

Regression testing

User Acceptance testing etc..

8. Functionality testing involves checking the following

Installation and setup on localized systems running
localized operating systems and pages with local
code.

Content handling, (for example, copying, pasting,
and altering) of augmented characters,
extraordinary textual styles, and non-Latin scripts.

String taking care of, content, and information,
particularly when interfacing with non-Unicode
applications or modules.
