Essential Statics Measures Interview Questions & Answers:

1. List some measure used in the study of static measures?

The measures used in this study are eight:
☛ Number of sentences
☛ Number of atomic conditions per decision
☛ Total number of decisions
☛ Number of equalities
☛ Number of inequalities
☛ Nesting degree
☛ McCabe's cyclomatic complexity
☛ Branch coverage

2. What are the kinds of measures?

There are 2 kinds of measures:
Dynamic Measures:
Which requires the execution of the program.
Static Measures:
Which does not require the execution.

3. What does cyclomatic complexity apply to?

Cyclomatic complexity may also be applied to individual functions, modules, methods or classes within a program, and is formally defined as follows:
v(G) = E − N + 2P
where E is the number of edges of the graph, N is the number of nodes of the graph and P is the number of connected components.

4. How is cyclomatic complexity computed?

Cyclomatic complexity is computed using the control flow graph of the program, the nodes of the graph correspond to indivisible groups of sentences of a program and a directed edge connects two nodes if the second sentence might be executed immediately after the first sentence.

5. What is a cyclomatic complexity?

Cyclomatic complexity is a complexity measure of code related to the number of ways there exists to traverse a piece of code. This measure determines the minimum number of test cases needed to test all the paths using linearly independent circuits.

6. What is statement coverage?

Statement coverage is defined as the percentage of statements that are executed.

7. What is a branch coverage?

branch coverage is the percentage of branches exercised in a program. This coverage measure is used in most of the related papers in the literature.

8. What is a nesting degree?

The nesting degree is the maximum number of conditional statements that are nested one inside another.

9. What is number of inequalities?

The number of (in)equalities is the number of times that the operator is found in atomic conditions of a program.

10. What are quantitative models?

Quantitative models are frequently used in different engineering disciplines for predicting situations, due dates, required cost and so on. These quantitative models are based on some kinds of measure performed on project data or items.
