in hardware component level testing is testing of individual
components whereas unit level testing is the entire unit
which may contain hundred of different kinds of components.
For example a test that may take 3 weeks with 10 units, will
take only half of the time if there is 2 of the component
under test in each unit, and a component level test being
done only on that particular component (if everything else
is assumed to be okay)/
Component Testing means Module Testing i.e we are testing
each module or component differently. suppose there is one
project which consists of 10 components and we are testing
each component differently then it is known as component
Testing, after component Testing Integration Testing is
done. while doing Black Box Testing or White Box Testing by
Tester first of all Component Testing is done.
Component Testing-Integration Testing-System Testing
The above is the actual scenerio before component Testing
Unit Testing is done by the developers.
While doing Unit Testing the Developers runs each
functions/method of the Component/Module.
Componnet testing searches for defects in and verifies the
functioning of s/w(e.gModules,Programmes, Objects, Classess
etc.)that are seperatly testable.Stubs, Drivers and
Simulators may be used.Component testing occurs with access
to the code being tested and with the support of the
development enviornment(Unit test Framework or Debugging
tool)Here defects are typically fixed as soon as they are
found, without formally recording incidents.
Examples of Compnents are..
Memory leak, Robustness testing, Structural Testing(Branch
componont testing is a anything that can be tested
independently. one of the best example is unit testing.
in the unit testing we define
procedures/methods/functions,if u want to test the above
proceures we just create some test procedures withthe help
of unit testig frame working
i ask about job to friends but all people in software
testing gives suggestion.why they did not help for getting
call and at least gives one chance .we will show what we
are??but by giving only suggestion .is not write ans.see
many people from andrha pradesh giving refrences to there
people .why other people not follow to them.
