Question #1

Which of the following is correct with regards to debugging?

A . Debugging identifies the cause of a failure
B . Debugging is often performed by test engineers
C . Debugging is considered part of the testing activities
D . Debugging is intended to find as many defects as possible in the code

Correct Answer: A
A

Explanation:

Debugging is the process of finding, analyzing and removing the causes of failures in software. Debugging is not considered part of testing, but rather a development activity that can involve testing. Debugging is not intended to find as many defects as possible, but rather to fix the specific failure that was observed. Debugging is usually performed by developers, not by test engineers.

Question #2

Which statement about use case testing is true?

A . The lest cases are designed to find defects in the data flew.
B . The test cases are designed to be used by real users, not by professional testers
C . The test cases are always designed by customers or end users.
D . The test cases are designed to find defects in the process flow.

Correct Answer: D
D

Explanation:

Use case testing is a technique that helps identify test cases that exercise the whole system on a transaction by transaction basis from start to finish. Use cases are descriptions of how users interact with the system to achieve a specific goal. Use case testing is not focused on data flow, but rather on process flow. Use case testing can be performed by professional testers, customers or end users, depending on the context. Use case testing does not require the test cases to be designed by customers or end users, but rather by anyone who has access to the use case specifications.

Question #3

A software module to be used in a mission critical application incorporates an algorithm for secure transmission of data.

Which review type is most appropriate to ensure high quality and technical correctness of the algorithm?

A . Walkthrough
B . Informal Review
C . Technical Review
D . Management Review

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

A technical review is a type of formal review that involves a team of technical experts who evaluate a software product against a set of predefined quality criteria. A technical review is suitable for ensuring high quality and technical correctness of complex or critical software components, such as algorithms, architectures or designs. A technical review is not a walkthrough, which is an informal review led by the author of the work product. A technical review is not an informal review, which is a review that does not follow a defined process and has no formal entry or exit criteria. A technical review is not a management review, which is a type of formal review that focuses on business aspects and project progress.

Question #4

Which of the following is NOT a deciding factor m determining the extent of testing required?

A . Level of risk of the product or features
B . Budget to do testing
C . A particular tester involved in testing
D . Time available to do testing

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

The extent of testing required for a software product depends on various factors, such as the level of risk, the budget, and the time available. The level of risk reflects the potential impact of failures on the stakeholders and the environment. The budget determines how much resources can be allocated for testing. The time available defines the schedule and deadlines for testing activities. The particular tester involved in testing is not a deciding factor for the extent of testing required, as testing should be based on objective criteria and not on personal preferences or abilities.

Question #8

If not ST certified with 5-10 years of testing experience – allow limited access.

What would be the results for:

A – ST certified. 12 years of testing experience

B – Not ST certified. 7 years of testing experience

C – Not ST certified. 3 years of testing experience

A . A – unknown
B – limned access
C- unknown
B . A – full access
B – limited access
C – unknown
C . A – full access
B – limited access
C – limited access
D . A – unknown
B – full access
C – unknown

Reveal Solution Hide Solution

Correct Answer: B
B

Explanation:

The correct answer can be derived by applying the given rules to each case:

A is ST certified and has 12 years of testing experience, which is more than 10 years. Therefore, A does not match any of the rules and the result is unknown.

B is not ST certified and has 7 years of testing experience, which is between 5 and 10 years.

Therefore, B matches rule 3 and the result is limited access.

C is not ST certified and has 3 years of testing experience, which is less than 5 years. Therefore, C does not match any of the rules and the result is unknown.

Question #9

A system computes prices for bus tickets.

The price depends on

– the passenger type (baby, child, adult, senior citizen, student, military)

– the travelling type (as single or in a group)

– the distance (zone 1. 2. 3)

– the kind of transport (ordinary, express)

Which of the following test techniques is the most appropriate one for testing the price computation?

A . Statement coverage
B . State transition testing
C . Equivalence partitioning
D . Use case testing

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

Equivalence partitioning is a technique that divides the input data and output results of a software component into partitions of equivalent data. Each partition should contain data that is treated in the same way by the component. Equivalence partitioning can be used to reduce the number of test cases by selecting one representative value from each partition. Equivalence partitioning is suitable for testing the price computation, as it can identify different partitions based on the passenger type, the travelling type, the distance and the kind of transport. Equivalence partitioning is not statement coverage, which is a technique that measures how many executable statements in a source code are executed by a test suite. Statement coverage is not appropriate for testing the price computation, as it does not consider the input data or output results. Equivalence partitioning is not state transition testing, which is a technique that models how a system transitions from one state to another depending on events or conditions. State transition testing is not relevant for testing the price computation, as it does not involve any states or transitions. Equivalence partitioning is not use case testing, which is a technique that tests how users interact with a system to achieve a specific goal. Use case testing is not applicable for testing the price computation, as it does not focus on a single function or component.

Question #10

Which test approach will best fit a new project, with little documentation and high probability for bugs?

A . Exploratory testing
B . Requirements based testing
C . Metric based approach
D . Regression testing

Reveal Solution Hide Solution

Correct Answer: A
A

Explanation:

Exploratory testing is an approach to testing that emphasizes learning, test design and test execution at the same time. Exploratory testing relies on the tester’s skills, creativity and intuition to explore the software under test and discover defects. Exploratory testing is suitable for a new project with little documentation and high probability for bugs, as it can help uncover unknown requirements, assumptions and risks. Exploratory testing is not requirements based testing, which is an approach to testing that derives test cases from documented requirements or specifications. Requirements based testing is not feasible for a new project with little documentation, as it requires clear and complete requirements to be available. Exploratory testing is not metric based approach, which is an approach to testing that uses quantitative measures to monitor and control the testing process and evaluate the quality of the software product. Metric based approach is not effective for a new project with high probability for bugs, as it may not capture all aspects of quality and may lead to false confidence or unrealistic expectations. Exploratory testing is not regression testing, which is an approach to testing that verifies that previously tested software still performs correctly after changes. Regression testing is not relevant for a new project with no previous versions or baselines.
