WHAT IS SOFTWARE TESTING ?

• SOFTWARE TESTING IS THE PROCESS OF EXECUTING
  PROGRAMS OR SYSTEM WITH THE INTENT OF FINDING
  ERORRS.
• SOFTWARE TESTING CAN ALSO BE STATED AS PROCEE OF
  VALIDATING AND VERIFYING THAT SOFTWARE PROGRAM/
  APPLICATION MEETS THE BUSINESS AND TECHNICAL
  REQUIREMENT.

3
SCOPE OF TESTING

• Scope of software testing often includes
  examination of code as well as execution of that
  code in various environments and conditions.
• It also examines the aspects of code does it do,
  what it is supposed to do and do what it needs to
  do .

4
TESTING METHODS

• Software testing methods are traditionally
  divided into
• WHITE BOX TESTING
• BLACK BOX TESTING
• GREY BOX TESTING

5
WHITE BOX TESTING

• White box testing is when the tester has access
  to the internal data structures and algorithms
  including the code that implement these.
• Types of white box testing
• API APIs testing - testing of the application
  using public and private
• Code coverage - creating tests to satisfy some
  criteria of code coverage (e.g., the test
  designer can create tests to cause all statements
  in the program to be executed at least once)
• Fault injection methods - improving the coverage
  of a test by introducing faults to test code
  paths.

6
BLACK BOX TESTING

• Black box testing treats the software as a"
  black box"without any knowledge of internal
  implementation.
• Black box testing methods include
• equivalence partitioning,
• boundary value analysis,
• model-based testing.

7
GREY BOX TESTING

• Grey box testing involves having knowledge of
  internal data structures and algorithms for
  purposes of designing the test cases, but testing
  at the user, or black-box level .

8
TESTING LEVELS

• Tests are frequently grouped by the level of
  specificity of the tests.
• The main levels during the development process
  are
• UNIT TESTING
• SYSTEM TESTING
• INTEGRATION TESTING

9

• UNIT TESTING Unit testing refers to tests that
  verify the functionality of a specific section of
  code, usually at the function level.
• INTEGRATION TESTING Integration testing is any
  type of software testing that seeks to verify the
  interfaces between components against a software
  design.
• SYSTEM TESTING System testing tests a
  completely integrated system to verify that it
  meets its requirements

10
OBJECTIVE OF TESTING

• Regression testing focuses on finding defects
  after a major code change has occurred.
  Specifically, it seeks to uncover old bugs that
  have come back. Such regressions occur whenever
  software functionality that was previously
  working correctly stops working as intended.
• Acceptance testing is performed by the customer,
  often in their lab environment on their own
  hardware .
• Alpha testing is simulated or actual operational
  testing by potential users/customers or an
  independent test team at the developers site .
• Beta testing comes after alpha testing and can be
  considered a form of external user acceptance
  testing. Versions of the software, known as beta
  versions, are released to a limited audience
  outside of the programming team
