Testing and Inspection Present and Future

• Software Engineering 2
• Term Project by
• Feras Batarseh Nestor Rivera

Questions!

• What are the differences between Inspection
• and Testing?
• Why people at industry aren't using Inspection?
• How to use Inspection efficiently?

3
Motivation

• Assessment behind statement Even though
• several empirical studies which compare
• inspection more favorably than testing, it is
• still not as widely used as testing

4
Ideas

• Achieve software quality greatest challenge.
• Testing is most recognized technique -gt no
  practical substitute
• Testing downfall defects uncovered late.
• Among other alternatives Software Inspections

5
Definitions

• Software Inspections are a disciplined
• engineering practice for detecting and
• correcting defects in software artifacts, and
• preventing their leakage into field operations.
• Software testing is any activity aimed at
  evaluating
• an attribute or capability of a program or system
• and determining that it meets its required
  results,
• making sure that its the valid system and
  verifying
• its work.

Inspections Benefits

• Different stages -gt Immediate detection
• Fagans Study 23 productivity improvement
• 38 Quality improvement
• Self Regulating (feedback)

10
Inspection Drawbacks

• Members distributed geographically
• Only mature process and organization
• Customer demands
• Personality issues
• Give/ receive feedback
• Severe stress
• Up-front cost
• Long run benefits
• Tools and training

11
Inspections Alternative Approach

• Virtual/Online Software Inspections
• Inspection methods that eliminate meetings are
• at least as cost-effective as methods that rely
• heavily on them.
• The benefits of holding a meeting is less than
• the benefits of letting individuals work alone.

Testing Types

• Unit testing
• Integration testing).
• Functional testing
• System testing
• Acceptance testing
