tell me the detailed exaplanation of different types of
tesiting
Answer Posted / jaiguru datta
Once the Build is migrated to the QA Environment.,Testers
start the testing with "Minimum Acceptance testing",,this
test is done just to make sure that the application is
acceptable for testing in otherwords application is working
normal..then we go for "module testing" where we do indepth
testing of the each module applying negative and positive
data(valid and invalid),here we test each functionality and
field ,for this purpose we set test data.then we go
for "Integration testing"..during this phase of testing
TestLead communicates with testers,so that they have
better understanding of each individual module before
integrating them,since the knowledge of integration depends
on many modules ans systems.These diverse modules could
have different ways of working when integrated with othr
systems.set of testcases are written and executed.Then we
go for "System testing".here all the components of the
system are integrated and tested as a single unit.As a part
of system testing we docouple of testings like..a) browser
compatibity testing to see whether it is compatible with
all browsers specified in requirements.b)Security testing
here we see whether the applicaton is secure from
unauthorized accesories and from unwanted
privileges,basically we see authorization and access
control.c)load testing,we test the appln by applying no of
users accessing the appln simultaneously and see how it
responds.Then comes "system integration testing" this
testing comes into picture when we have two appln to
integrate.Then comes "Regression Testing",this is done to
see that a new feature introduced to the existing product
does not adversely affect the current functionality.
but we can never say regression testing will be conducted
on after the end os syatem testing or system integration
testing...if ur Testlead asks you to conduct regression
testing after module testing we have to do.Regression
testing is done in between builds and test cycles.many
automated tools are used to carryout this testing.
You have many more testings like smoke,sanity ,user-
acceptance(alpha,beta)..but unit testing usually not done
by testers unless you have the knowledge of the code.
I mentioned all basic kinds of tests which are implemented
in evry company,but thr are many different tests which
change company to comapny..as mentioned by othrs in above
answers.
