Debugging Flashcards
What two criteria should operational definitions meet?
Communication and Repeatability
How much does each decision increase the cyclomatic complexity?
1
What is program verification?
Aims at proving the correctness of programs by showing that it contains no errors
The entity that performs the task of checking the correctness of the observed behavior
Oracle
What cyclomatic complexity is considered challenging?
10-20
Counting the implemented methods in a class
Weighted Methods per Class
T/F Use of measurement data to evaluate individuals will negatively affect the correctness and usefulness of the measurement data that are reported
T
Dissimilarities between methods by using attributes used in the methods
Lack of Cohesion of Methods
T/F Comprehensive test coverage is impractical for hardware or software testing
T
A standard of measurement
Metric
T/F Dynamic metrics do not require code execution
F
Is Goal-driven measurement based on a predefined set of measures?
No
In goal-driven measurement, what is the primary question?
What do I want to know or learn?
Help focus investigations by ranking problems, causes, or actions in terms of their amounts, frequency of occurrence, or economic consequences
Pareto Charts
T/F The act of measuring and analyzing will not change behavior
F
Mathur recommends a cyclomatic complexity less than _?
5
The act of measuring (paying attention) will change behavior
Hawthorne Effect
T/F Static metrics can be computed without executing the program
T
Number of classes that directly inherit one class
Number of Children
T/F Program verification and testing should be
considered complementary techniques
T
Depth of Inheritance
Maximum number of nodes between root and lowest node in the hierarchy
The process of determining the cause of errors and removing them
Debugging
Number of methods a class is accessible to,
including methods implemented in own class
as well as methods accessible due to
inheritance
Response for a Class
T/F It is more common to measure “Halstead time” in terms of months
F, minutes
Coupling Between Objects
Number of other classes that a class is coupled to
programming – The art of:
Debugging a blank sheet of paper
T/F State transition diagrams can be used to specify
program behavior
T
Human testers are what three things?
error-prone
slow
may result in trivial checks
What are the two measurement questions?
Are we measuring the right thing?
Are we measuring it right?
T/F An operational definition [is one] which reasonable men can agree on and do business with
T
How is a defect defined?
severity, criticality, impact
What do you see if the 80/20 rule does not apply?
Flat pareto
What is Pareto chart interpretation based on?
80/20 rule
The rules and procedures used to capture and record data
Operational Definitions
What two things should be considered complementary techniques?
Program verification and testing
What can be used to specify program behavior?
State transition diagrams
