Answer / prashanth

functional testing is a testing process where we test the
functionality/behaviour of each functional component of the
application...i.e.minimize button,transfer button,links etc.
i.e we check what is each component doing in that
application...

regression testing is the testing the behaviour of the
application of the unchanged areas when there is a change
in the build.i.e we chk whether the changed requirement has
altered the behaviour of the unchanged areas.

the impacted area may be the whole of the application or
some part of the application...

Hi,

In Functionality testing we are going to check the
functionality is working as expected to the client
specified requirement.

In regression testing means after getting confirmation
the bug is fixed we are going to check the fixation is
going to create any problems in the application or not...

Answer / kumar

Functionality testing is to test the functional behaviour
of each and every component in the application. its tested
against both positive and negative aspects.
Regression testing is the re-execution of same old test
cases written for earier releases.

Answer / govardhan reddy

Regression testing is any type of software testing that
seeks to uncover new software bugs, or regressions, in
existing functional and non-functional areas of a system
after changes, such as enhancements, patches or
configuration changes, have been made to them.

Answer / manjunath.k

Simple terms:

Regression Testing(Old Or existing functionality) wheres
Functional Testing is testing new requirement of the
existing functionality.

Ex: I have pulsar 150 CC-Regression Testing. New requirement
i need 180 CC BIKE pulsar(functional=NEW requirement). Bajaj
will check if i go for 180 CC pulsar nothing will happen to
any parts of 150 CC Bike PULSAR. So Testing all parts i.e
Regression testing in 150 CC pulsar and functional testing
of 180 CC pulsar. Its just only CC changed.

Conclusion: If i change from 150 to 180 CC den nothing
should alter except Engine CC. Thats it:)

A major part of black box testing is functional tetsing.
testing team more concentrate on functional testing.
for ex any gui application the basic functionality will be
like these.
if u click on minimized button it will be minimized .
if u click on submit button it will go to the next page.

regresion testing means in any application new functiality
can be added so the application has to be tested to see
whether the added functialityes are affected by the
exsiting functiality or not.
