what is the difference b/w system testing & functional
testing ?

Answer Posted / sahil mahajan

System Testing: Once the components are integrated, the
system as a whole needs to be tested to confirm that it
meets the quality standard. System testing will be to verify
that it meets the functional and technical requirements.
System testing is also resembles like a production stage
where the process will actually run but it will still under
testing phase to perform the other types of testing if
needed and then finally test again under UAT.

Functional Testing: In functional testing we will check the
actual functionality of the application which will verify
that it matches the business requirements, the requirements
which we got from client or from use cases designs. There
are number of types of testing which will come under
functional testing like : Unit testing, Integration testing,
User acceptance testing, smoke / sanity / regression
testing, localization and globalization testing.
