Component testing, also known as unit, module, or program testing, involves individually testing each component or module of a website or application in isolation from the full system. This includes testing each page of a website separately and using stubs and drivers to replace missing dependencies. Component testing checks for issues like memory leaks and validates performance before integration testing brings components together into a full system.

2. • Component Testing also called Unit, Module and
Program testing
• For example if website has 5 pages, than testing of
each page is done separately in Component testing
• Component testing is usually done after unit testing
done by developers
• In component testing each module is tested
separately
• Component testing may be done in isolation from the
rest of the system

• Stubs(is called from the software component to be
tested) and Drivers(a driver calls a component to be
tested) are used to replace the missing software
• Testing may include testing memory leaks and per-
formance testing
• Integration testing is followed by Component testing
