23. Frage
Which of the following statements best describe Behavior-Driven Development (BDD)?
Antwort: B
Begründung:
Behavior-Driven Development (BDD) is a collaborative approach that enhances communication among project stakeholders, including developers, testers, and business analysts. It involves defining how software should behave through examples written in a common language understandable by all stakeholders, often using the Given-When-Then format.
24. Frage
Which of the following s the most correct statement about state testing techniques?
Antwort: C
Begründung:
State testing techniques are a type of dynamic testing techniques that are based on the behavior of the system under test for different input conditions and events. Dynamic testing techniques require the system to be executed with test cases, whereas static testing techniques do not. Static testing techniques can be applied before the code is ready for execution, such as reviews, inspections, walkthroughs, and static analysis. Static testing techniques can help find defects early in the development process, improve the quality of the code, and reduce the cost and effort of dynamic testing.

25. Frage
Scenario "Happy Tomatoes"
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 the equivalence partitioning technique, identify the set of input values that provides the HIGHEST coverage.
Antwort: A
Begründung:
Using Equivalence Partitioning, we select one representative value from each valid partition:
W (t ≤ 7): select 7
X ([8-21]): select 10
Y ([22-29]): select 25
Z (t ≥ 30): select 40
This set covers all four equivalence classes, so it provides the highest coverage.
26. Frage
The fact that defects are usually not evenly distributed among the various modules that make up a software application, but rather their distribution tend to reflect the Pareto principle:
Antwort: A
Begründung:
The fact that defects are usually not evenly distributed among the various modules that make up a software application, but rather their distribution tend to reflect the Pareto principle, is expressed by the testing principle referred to as 'Defects cluster together'. This principle states that a small number of modules contain most of the defects detected, or that a small number of causes are responsible for most of the defects. This principle can be used to guide the test analysis and design activities, by prioritizing the testing of the most critical or risky modules, or by applying more rigorous test techniques to them. Therefore, option C is the correct answer.

27. Frage
Which of the following issues cannot be identified by static analysis tools?
Antwort: D
Begründung:
Static analysis tools are software tools that examine the source code of a program without executing it. They can detect various types of issues, such as syntax errors, coding standardsviolations, security vulnerabilities, and potential bugs12. However, static analysis tools cannot identify issues that depend on the runtime behavior or performance of the program, such as very low MTBF (Mean Time Between failure)3. MTBF is a measure of the reliability of a system or component. It is calculated by dividing the total operating time by the number of failures. MTBF reflects how often a system or component fails during its expected lifetime. Static analysis tools cannot measure MTBF because they do not run the program or observe its failures. MTBF can only be estimated by dynamic testing, which involves executing the program under various conditions and collecting data on its failures4. Therefore, very low MTBF is an issue that cannot be identified by static analysis tools. The other options, such as potentially endless loops, referencing a variable with an undefined value, and security vulnerabilities, are issues that can be identified by static analysis tools. Static analysis tools can detect potentially endless loops by analyzing the control flow and data flow of the program and checking for conditions that may never become false5. Static analysis tools can detect referencing a variable with an undefined value by checking the scope and initialization of variables and reporting any use of uninitialized variables6. Static analysis tools can detect security vulnerabilities by checking for common patterns of insecure code, such as buffer overflows, SQL injections, cross-site scripting, and weak encryption.
