7.SYSTEM TESTING<br />
S<strong>of</strong>tware testing is a critical element <strong>of</strong> quality assurance <strong>and</strong> represents the<br />
ultim<strong>at</strong>e preview <strong>of</strong> specific<strong>at</strong>ions, design <strong>and</strong> coding. Testing represents an<br />
interesting anomaly for the s<strong>of</strong>tware. Doing the earlier definition <strong>and</strong> development<br />
phase it was <strong>at</strong>tempted to buid a s<strong>of</strong>tware from an abstract concept to a tangiable<br />
implement<strong>at</strong>ion. The various types <strong>of</strong> testing done on the system is<br />
a. Unit testing<br />
b. Integr<strong>at</strong>ion Testing<br />
c. Valid<strong>at</strong>ion Testing<br />
Unit testing<br />
A unit focuses verific<strong>at</strong>ion effort on the smallest limit <strong>of</strong> s<strong>of</strong>tware<br />
design. Using the unit test plan prepared in the design phases <strong>of</strong> the system,<br />
important control p<strong>at</strong>hs are tested to uncover the errors within the module.<br />
This testing was carried out during the coding itself.<br />
Integr<strong>at</strong>ion Testing<br />
Integr<strong>at</strong>ion testing is the system<strong>at</strong>ic technique for constructing the<br />
program structure while <strong>at</strong> the same time conducting test to uncover errors<br />
associ<strong>at</strong>ed with the interfaces. The objective is to take unit tested modules<br />
<strong>and</strong> build the program structure th<strong>at</strong> has been dict<strong>at</strong>ed by design. All<br />
modules are combined in this testing step.<br />
Valid<strong>at</strong>ion Testing<br />
At the end <strong>of</strong> integr<strong>at</strong>ion testing, s<strong>of</strong>tware is completely assembled as a<br />
package, interfacing errors have been uncovered <strong>and</strong> corrected <strong>and</strong> final<br />
series <strong>of</strong> s<strong>of</strong>tware valid<strong>at</strong>ion <strong>and</strong> testing begins<br />
Debugging<br />
Debugging is the process <strong>of</strong> isol<strong>at</strong>ing <strong>and</strong> correcting the cause <strong>of</strong> known<br />
errors. Success <strong>at</strong> debugging requires highly developed problems skills.<br />
Commonly used debugging methods include induction, deduction <strong>and</strong><br />
backtracking. Debugging by induction involves the following steps<br />
