BCS ISTQB Certified Tester Foundation Level CTFL 4.0 CTFL4 Prüfungsfragen mit Lösungen (Q70-Q75):

70. Frage
Which statement is true regarding confirmation testing and regression testing?

A. TESTER Involvement is essential whilst running retesting and regression testing.
B. Testers' involvement is essential whilst running retesting and regression testing.
C. Confirmation testing is an optional activity whilst regression testing is not negotiable.
D. Confirmation testing confirms the quality of the test being run while regression testing ensures that the software still works after a change has been made.
E. Confirmation testing aims to verify that a defect has been resolved and regression testing ensuring that existing functionality still works after a change.

Antwort: E

Begründung:
Confirmation testing, also known as retesting, is conducted to verify that specific defects have been fixed.
Regression testing, on the other hand, is performed to ensure that recent changes have not adversely affected existing features of the software. Both types of testing are crucial for maintaining the integrity and quality of the software after modifications.

71. Frage
Which of the following statements about white-box test techniques is true?

A. Code-related white-box test techniques are not required to measure the actual code coverage achieved by black-box testing, as code coverage can be measured using the coverage criteria associated with black-box test techniques
B. Branch coverage is the most thorough code-related white-box test technique, and therefore applicable standards prescribe achieving full branch coverage at the highest safety levels for safety-critical systems
C. Achieving full statement coverage and full branch coverage for a software product means that such software product has been fully tested and there are no remaining bugs within the code
D. Code-related white-box test techniques provide an objective measure of coverage and can be used to complement black-box test techniques to increase confidence in the code

Antwort: D

Begründung:
This answer is correct because code-related white-box test techniques are test design techniques that use the structure of the code to derive test cases. They provide an objective measure of coverage, such as statement coverage, branch coverage, or path coverage, which indicate how much of the code has been exercised by the test cases. Code-related white-box test techniques can be used to complement black-box test techniques, which are test design techniques that use the functional or non-functional requirements of the system or component to derive test cases. By combining both types of techniques, testers can increase their confidence in the code and find more defects.

72. Frage
The acceptance criteria associated with a user story:

A. can be written in different formats and represent an aspect of a user story referred to as confirmation' of the so called "3 C's"
B. must be written in one of the two following formats: scenario-oriented or rule-oriented
C. are often written in a rule-oriented format using the template referred to as "Given/When/Then"
D. are often documented following in rule-oriented format using the following template: "As a [role], I want [feature], so that I can [benefit]"

Antwort: A

Begründung:
The acceptance criteria associated with a user story are the conditions that must be met for the user story to be considered done and to deliver the expected value to the user. They are often written in different formats, such as rule-oriented, scenario-oriented, or table-oriented, depending on the nature and complexity of the user story. They represent an aspect of a user story referred to as confirmation, which is one of the so called "3 C's" of user stories. The other two aspects are card and conversation. Card refers to the concise and informal description of the user story, usually following the template: "As a [role], I want [feature], so that I can [benefit]". Conversation refers to the ongoing dialogue between the stakeholders and the team members to clarify and refine the user story and its acceptance criteria. Therefore, option C is the correct answer.

73. Frage
A document descnbes the test procedures that have been derived for the identified test sets Among other things, the order in which the test cases in the corresponding test set are to be executed according to the dependencies described by preconditions and postconditions is specified This document is a typical work product produced as part of:

A. Test analysis
B. Test design.
C. Test monitoring and control
D. Test Implementation.

Antwort: D

Begründung:
Test implementation involves finalizing the test procedures, including the order of execution of test cases based on their dependencies, preconditions, and postconditions. This phase ensures that all necessary test scripts, test data, and test environments are ready for execution. According to the ISTQB CTFL Syllabus v4.0, test implementation is the phase where detailed test procedures are derived and documented, making it a critical step before actual test execution.

74. Frage
Scenario 1 "Happy Tomatoes" (used for questions 20-22):
An intelligent application for agricultural use incorporates temperature sensors located at different points of an enclosure. The sensors measure and record the temperature at regular intervals and extract the statistical values for these measurements. These values include the average daily temperature.
A new variety of tomatoes is currently being grown and the"World Organization for Happy Tomatoes"has established temperature ranges related to vegetative development.
When the system establishes that the average temperature is within a specific range, it emits a value that will be used to monitor and control the crop.

Using theequivalence partitioningtechnique, identify the set of input values that provides the HIGHEST coverage.

A. {8,10,25,40}
B. {7,10,25,29}
C. {7,10,21,40}
D. {7,10,25,40}

Antwort: B

Begründung:
Comprehensive and Detailed In-Depth Explanation:Equivalence partitioning (EP)divides input values into classes where test casesrepresent all possible valuesof each partition. The partitions in this scenario are:
* #7 (too cold # W)
* 8-21 (standstill # X)
* 22-29 (ideal # Y)
* #30 (too hot # Z)
OptionC ({7,10,25,29})covers all partitionsby selecting representative values:
* 7 # Too cold (W)
* 10 # Standstill (X)
* 25 # Ideal (Y)
* 29 # Upper boundary of ideal (Y)
Other options do not cover all partitions adequately.
