a) Bug prevention
b) Testing
c) Execution
d) Analyses
Answer: A
It’s better to prevent a bug rather than putting time into its testing and removal.
2. Software mistakes during coding are known as
a) errors
b) failures
c) bugs
d) defects
Answer: C
A software bug is an error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result.
3. Name an evaluation technique to assess the quality of test cases.
a) Mutation analysis
b) Validation
c) Verification
d) Performance analysis
Answer: A
Mutation analysis is used to design new software tests and evaluate the quality of existing software tests.
4. Test should be conducted for every possible
a) data
b) case
c) variable
d) all of the mentioned
Answer: D
It increases the scope for code inspection.
5. Which of the following is not a part of the bug report?
a) Test case
b) Output
c) Software Version
d) LOC
Answer: D
Line of code(LOC) is immaterial during testing, as it is an exhaustive process.
The phrase “lines of code” (LOC) is a metric generally used to evaluate a software program or codebase according to its size.
It is a general identifier taken by adding up the number of lines of code used to write a program.
6. Which of the following is not a part of Execution Flow during debugging?
a) Step Over
b) Step Into
c) Step Up
d) Step Out
Answer: C
Step Into executes code, Step Out continues execution until bound value, and Step Over is to execute code without stopping.
Stepping through code means executing the code one line at a time. Stepping allows you to see the exact sequence of execution and the value of the various variables at each step.
7. Cyclomatic Complexity method comes under which testing method.
a) Yellow box
b) White box
c) Gray box
d) Black box
Answer: B
Cyclomatic Complexity tells us about the number of independent paths in a program which is covered in white box testing.
Cyclomatic complexity is a measurement developed by Thomas McCabe to determine the stability and level of confidence in a program.
8. Which is a black-box testing technique appropriate to all levels of testing?
a) Acceptance testing
b) Regression testing
c) Equivalence partitioning
d) Quality assurance
Answer: C
Equivalence partitioning is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived.
9. Which of the following is the way of ensuring that the tests are actually testing code?
a) Control structure testing
b) Complex path testing
c) Code coverage
d) Quality assurance of software
Answer: C
Code coverage is the way of ensuring that the tests are actually testing code. Code coverage is a software testing metric that determines the number of lines of code that are successfully validated under a test procedure, which in turn, helps in analyzing how comprehensively a software is verified.
10. Effective testing will reduce _______ cost.
a) maintenance
b) design
c) coding
d) documentation
Answer: A
The remaining options are a part of the development process. Effective testing will reduce maintenance costs.
