SE4452 Testing Midterm Flashcards
What are the quality factors in ISO 9216
- Functionality
- Reliability
- Usability
- Efficiency
- Maintainability
- Portability
Which ISO 9216 quality factor includes security?
Functionality
Name the quality criteria:
Attributes of software that bear on the frequency of failure by faults in the software
Maturity
Name the quality criteria:
Attributes of software that bear on the amount of resources used and the
duration of such use in performing its function.
Resource Behavior
Name the quality criteria:
Attributes of software that bear on the users’ effort for operation and operation
control.
Operability
Name the quality criteria:
Attributes of software that bear on the provision of right or agreed results or effects
Accuracy
Which quality factor(s) does not include compliance as a quality criteria?
Reliability
Certainly
Certainly
What are the three dimensions of quality?
- entity
- viewpoint
- attribute
What are the 3 states in McCall’s quality model?
Product operation
product revision
product transition
What is the major difference between ISO 9126 and McCall?
ISO 9126 reflects a user view
McCall reflects a product view
Whats does the + in FURPS+ represent?
Design
Implementation
Interface
Physical
What does FURPS stand for?
Functional Usability Reliability Performance Supportability
What are the two categories of FURPS+?
Functional
Non-functional
What are the quality factors of SEI?
Performance
Dependability
Security
Safety
What are the 4 types of quality measurements?
Static
Dynamic
Direct
Indirect
What is a dynamic quality measurement?
Based on observation of execution (e.g. CPU execution time)
What is an indirect quality measurement?
Derived from a direct measurement (e.g. failure intensity = # failures / hour)
What is SMI?
Software Maturity Index - assessment of release readiness
What is the formula for SMI?
SMI = ( Mt - (Fc + Fa + Fd) ) / Mt
What is the difference between expected failures and failure intensity?
Expected failures is the number of failures expected in period t, while failure intensity is the actual number of failures experiences in period t
What is service degradation rate?
The % of functions that are unrecoverable
What are criteria of functionality?
ISSAC
Interoperability Suitability Security Accuracy Compliance
What are the criteria of reliability?
MCFR
Maturity
Crash frequency
Fault tolerance Recoverability
