difference betw. unit and compo. testing ....
Unit - The smallest compilable component. A unit typically
is the
work of one programmer (At least in principle). As defined,
it does
not include any called sub-components (for procedural
languages) or
communicating components in general.
Unit testing: in unit testing called components (or
communicating
components) are replaced with stubs, simulators, or trusted
components. Calling components are replaced with drivers or
trusted
super-components. The unit is tested in isolation.
Component: a unit is a component. The integration of one or more
components is a component.
Note: The reason for "one or more" as contrasted to "Two or
more" is to allow for components that call themselves
recursively.
Component testing: the same as unit testing except that all
stubs
and simulators are replaced with the real thing.
Two components (actually one or more) are said to be
integrated when:
a. They have been compiled, linked, and loaded together.
b. They have successfully passed the integration tests at the
interface between them.
Thus, components A and B are integrated to create a new, larger,
component (A,B). Note that this does not conflict with the
idea of
incremental integration -- it just means that A is a big
component
and B, the component added, is a small one.
