software testing:
Software testing is an essential part of software development which is used to identify the correctness, completeness and quality of developed software.
Software testing is the process used to help identify the correctness, completeness, security & quality of developed computer software.
Its main objects are to detect error in software.
levels in testing:
1. Unit Testing.
2. Integration Testing.
3. System Testing.
4. Acceptance Testing.
5. Regression testing.
Unit Testing:
A unit is smallest testable piece of software.
– can be compiled, linked, loaded.
– e.g functions/procedures, classes, interfaces.
– normally done by programmer.
– Test cases written after coding.
Disadvantage:
– Test cases ‐written to suit programmer’s implementation.
Integration testing:
Test for correct interaction between system units.
systems ‐ built by merging existing libraries.
modules coded by different people.
Mainly tests the interfaces among units.
Bottom up integration testing.
-Use of drivers
Top down integration testing.
-Use of stubs
System Testing:
Test of overall interaction of components.
Find disparities between implementation and
specification.
Usually where most resources go to.
Involves – load, performance, reliability and security testing.
Acceptance Testing:
Demonstrates satisfaction of user.
Users are essential part of process.
Usually merged with System Testing.
Regression Testing:
On going process throughout testing life cycle.
New bug‐fix breaks previously tested units?
Perform regression test whenever program changes.
Done by test team and customer.
Done in simulated environment/real environment.

Answer / asha
There are two levels of testing:
1. Static Testing
2. Dynamic Testing
1. Static Testing: Static testing typically reviews and
meetings to evaluate the documents, plans, code,
requirements and specification.
2. Dynamic Testing:
a)Unit Testing
b)Integration Testing
c)System Testing
d)User Acceptance Testing
a)Unit Testing: To test a single program,module,or unit of
code.
b)Integration Testing: To test related programs,modules or
units of code are interfaced properly or not validates that
multiple parts of the system interact according to the
system design.
c)System Testing: To test an entire computer system with
respect to functionality and performance.
d)User Acceptance Testing: The end user tests the
application to check whether the it is as per customers
requirements or not.
