TESTING
10
Test Plans

• The following input is required to test an
  application block
• Functional specifications
• Requirements
• Performance objectives

11
Test Plans

• Test Methods
• Regression Testing
• Integration Testing
• Black Box Testing ( Stress Testing )
• Unit Testing ( N Unit )

12
Test Plans

• Regression Testing
• Test fixed bugs promptly.
• Watch for side effects of fixes.
• Write a regression test for each bug fixed.
• If two or more tests are similar, determine which
  is less effective and get rid of it.
• Identify tests that the program consistently
  passes and archive them.
• Focus on functional issues, not those related to
  design.
• Make changes (small and large) to data and find
  any resulting corruption.

13
Test Plans

• Integration Testing
• Def A type of testing in which software and/or
  hardware components are combined and tested to
  confirm that they interact according to their
  requirements
• Check Connections
• Pocket PC ----------? Web Server
• Web Server ?--------? SQL Server
• Pocket PC ----------? Speech Server
• Speech Server ----------? Web Server

14
Test Plans

• Stress Testing
• Evaluate the application block's behavior when it
  is pushed beyond peak load conditions.
• The goal of stress testing is to identify errors
  that occur only under high load conditions.

15
N-Unit Testing

• Unit-Testing Method For All .NET Languages
• Assertions
• Comparisons
• Condition Tests

16
Comparisons

• Report Expected and Actual Values
• Assert.AreEqual
• Both arguments are of the same datatype
• Ex.(Assert.AreEqual Int Expected, Int Actual) in
  Transfer Balance
• Assert.AreSame
• Same Objects are referenced by both arguments

17
Condition Tests

• Assert.IsTrue(Bool Condition)
• Assert.IsFalse(Bool Condition)
• Ex. Assert.IsTrue(hash.MeetsPassword(goodpass),
  Good password failed check)
• Assert.IsFalse(hash.MeetsPassword(badpass),
  Bad password passed check)

18
COCOMO

• Total lines of code 41.8 function points 53
  lines per function point
• Total lines of code 2215.4
• KLOC therefore equals 2.22
• E bKLOCc
• The basic COCOMO parameters for a semidetached
  project are b 3.0 and c 1.12
• E 3.0 (2.22)1.12
• E 7.328 staff months

19
COCOMO

• Student months 4 7.328 29.02
• 29.02 student months / 7 students 4.2 months
