In maintenance testing, What is the relationship between impact analysis and Regression testing? Select one:
- A.
  
  The impact analysis is used to evaluate the amount of regression testing to be performed
- B.
  
  Impact analysis requires a regression testing for only the tests that have detected faults in Previous SW release.
- C.
  
  There is no relation between impact analysis and regression testing.
- D.
  
  Impact analysis requires a regression testing for all program elements when there are new changes integrated (new functionalities).
Correct Answer
A. The impact analysis is used to evaluate the amount of regression testing to be performed

Explanation
Impact analysis is used to assess the potential impact of changes on the existing system. It helps in identifying the areas that are likely to be affected by the changes. Regression testing, on the other hand, is performed to ensure that the changes made to the system do not have any unintended side effects on the existing functionality. Therefore, the impact analysis is used to determine the extent of regression testing that needs to be performed.

Agile development can be classified as which life cycle model? Select one:
- A.
  
  Agile development is not related to any life cycle model
- B.
  
  V Model
- C.
  
  Iterative or incremental
- D.
  
  RAD
Correct Answer
C. Iterative or incremental

Explanation
Agile development can be classified as an iterative or incremental life cycle model. This is because Agile focuses on delivering software in small, incremental iterations, rather than following a linear, sequential process like the V Model. Agile also emphasizes flexibility and adaptability, allowing for changes and adjustments to be made throughout the development process. RAD (Rapid Application Development) is another life cycle model, but it is not the most suitable classification for Agile development. Therefore, the correct answer is iterative or incremental.

  Test planning is an activity that is only performed at the very beginning of the project.
- B.
  
  Test planning is influenced by among others, the scope of testing, the risks and the availability of resources.
- C.
  
  Since test planning is influenced by the developers work, test planning should not start before the entire project plan of the development team is available.
- D.
  
  Because independence of testers enhances quality and improves testing, test planning should not take into account constraints from the development
Correct Answer
B. Test planning is influenced by among others, the scope of testing, the risks and the availability of resources.

Explanation
The correct answer is "Test planning is influenced by among others, the scope of testing, the risks and the availability of resources." This statement is correct because test planning involves considering various factors such as the scope of testing, the risks involved, and the availability of resources. These factors play a crucial role in determining the test strategy, test objectives, and test approach. Therefore, test planning is not limited to the beginning of the project but is an ongoing activity that adapts and evolves based on these influences.

Which of the following are valid testing principles ? I. Exhaustive testing is in general impossible II. Exhaustive testing should be executed for code intended to be reused III. Testing may guarantee that a program is correct IV. Testing cannot guarantee that a program is correct V. Defects cluster together in certain areas of the product Select one:
- A.
  
  II, IV
- B.
  
  I, IV, V
- C.
  
  I, III
- D.
  
  I, V
Correct Answer
B. I, IV, V

Explanation
Exhaustive testing is generally impossible because it is impractical to test every possible input and scenario. Testing cannot guarantee that a program is correct because there may be undiscovered defects or errors. Defects tend to cluster together in certain areas of the product, meaning that there may be specific areas or functionalities that are more likely to have issues. Therefore, the valid testing principles are I, IV, and V.

  Statement coverage = 1, Branch coverage = 3
- B.
  
  Statement coverage = 2, Branch coverage = 4
- C.
  
  Statement coverage = 2, Branch coverage = 2
- D.
  
  Statement coverage = 1, Branch coverage = 2
Correct Answer
D. Statement coverage = 1, Branch coverage = 2

Explanation
The correct answer is Statement coverage = 1, Branch coverage = 2. This is because there are two if statements in the code fragment. The first if statement has two conditions, so there are two branches to consider. The second if statement has only one condition, so there is only one branch to consider. Therefore, the minimum number of tests required for branch coverage is 2. As for statement coverage, there are two assignments in the code fragment, so the minimum number of tests required for statement coverage is 1.

Select one:
- A.
  
  Decision table
- B.
  
  Equivalence class partitioning
- C.
  
  Use case based testing
- D.
  
  Boundary value analysis
Correct Answer
A. Decision table

Explanation
A decision table should be used to cover all possible combinations of the input conditions. A decision table is a testing technique that helps identify all possible combinations of inputs and their corresponding outputs or actions. In this case, the decision table can include the valid/invalid card, correct/incorrect PIN code, and available/unavailable money in the user's account as conditions, and the actions or outputs can be the rejection of the card, asking for another PIN code, asking for another amount, or dispensing the money. By creating a decision table, all possible combinations can be systematically tested to ensure comprehensive coverage.

Which of the following statements are true ? I. Defects in a program do not always cause failures. II. A defect in a program may cause more than one failure during execution III. If there is a fault in the program, at least one test will fail IV. After fixing a bug, the program may still fail under test V. Errors in the program lead to sideeffects Select one:
- A.
  
  II and III are true. The others are false
- B.
  
  I and IV are true. The others are false
- C.
  
  I, II and IV are true. The others are false
- D.
  
  I and V are true. The others are false
Correct Answer
C. I, II and IV are true. The others are false

Explanation
Defects in a program do not always cause failures, as there may be situations where the defect does not impact the program's functionality. A defect in a program may cause more than one failure during execution, as multiple parts of the program can be affected by the same defect. If there is a fault in the program, at least one test will fail, as faults represent errors or defects in the program's code. After fixing a bug, the program may still fail under test, as there could be other undiscovered defects or issues in the program. Errors in the program do not necessarily lead to side effects, as not all errors result in unintended consequences.

In what way do configuration management effects testing? Select one:
- A.
  
  Proper configuration management ensures that testers can uniquely identify the tested item
- B.
  
  Without proper configuration management, test planning cannot proceed
- C.
  
  There is very little influence of configuration management practices on the test project
- D.
  
  Configuration management is important for developers, not for testers
Correct Answer
A. Proper configuration management ensures that testers can uniquely identify the tested item

Explanation
Proper configuration management ensures that testers can uniquely identify the tested item. This means that testers can accurately track and manage the specific version or configuration of the item being tested. This is crucial for effective testing as it allows testers to reproduce issues, track changes, and ensure that the correct version of the item is being tested. Without proper configuration management, testers may encounter difficulties in identifying and managing the tested item, leading to inefficiencies and potential errors in the testing process.

- A.
  
  Interface complexity
- B.
  
  Data integrity
- C.
  
  Resource availability
- D.
  
  Performance
Correct Answer
C. Resource availability

Explanation
Resource availability is a project risk because it refers to the availability of necessary resources, such as personnel, equipment, or materials, that are required to complete a project. If there is a lack of resources or if they are not available when needed, it can lead to delays, increased costs, or even project failure. Therefore, resource availability is a potential risk that project managers need to consider and plan for in order to ensure the successful completion of a project.

  Set an entry criterion requiring fixes to be retested by a developer before accepting them into a build
- B.
  
  Writing test suspension and resumption criteria in the test plan
- C.
  
  Repriortize tests because of time pressure
- D.
  
  Change the test schedule due to availability of a test environment
Correct Answer
B. Writing test suspension and resumption criteria in the test plan

Explanation
The correct answer is "Writing test suspension and resumption criteria in the test plan." This is not a test control activity because it is a test planning activity. Test control activities are focused on monitoring and adjusting the testing process, such as setting entry criteria, reprioritizing tests, and changing the test schedule. Writing test suspension and resumption criteria is part of the test planning process, where the criteria for when to suspend and resume testing are defined in advance.

- A.
  
  There are three equivalence classes: two with valid names (upper and lower case), one invalid name
- B.
  
  There are two equivalence classes, One valid and one invalid station name
- C.
  
  This specification is not solvable by equivalence partitioning
- D.
  
  There are as many test cases as there are valid station name
Correct Answer
B. There are two equivalence classes, One valid and one invalid station name

Explanation
The explanation for the given correct answer is that the requirement snippet states that if the input is a valid station name (case-insensitive), then the code corresponding to the station name will be displayed. This means that there are two equivalence classes: one for valid station names (both upper and lower case) and one for invalid station names. The code will only be displayed for valid station names, so there is no need to create test cases for each valid station name separately.

Which of the following test execution outcomes are likely to increase the overall quality of the software: I. A test case passes II. A test case fails, defect gets logged which subsequently gets fixed III. Some tests are differed because test environment is not available IV. A bug is found but there is no corresponding test case Select one:
- A.
  
  I, II and III
- B.
  
  I and IV
- C.
  
  I and II
- D.
  
  I, II and IV
Correct Answer
D. I, II and IV

Explanation
Passing test cases (I) indicate that the software is functioning correctly and meets the expected requirements. When a test case fails (II), a defect is identified and logged, which can then be fixed to improve the software's quality. Even if a bug is found without a corresponding test case (IV), it still contributes to the overall quality as it highlights areas that need improvement. However, deferring tests (III) due to the unavailability of the test environment does not directly impact the quality of the software. Therefore, the correct answer is I, II, and IV.

Which of the following statements correctly characterize experiencebased techniques ? I. "Error guessing" is an experience based technique. II. Experience based techniques are alternative to systematic techniques. III. The fault attack is a structured approach to "error guessing". IV. Exploratory testing is an experience based technique, especially useful when the specifications are complete and the time schedule is not pressing. Select one:
- A.
  
  I, II
- B.
  
  I, III
- C.
  
  II, III
- D.
  
  I, III, IV
Correct Answer
B. I, III

Explanation
Experience-based techniques are testing techniques that rely on the tester's knowledge, intuition, and past experience. "Error guessing" is an experience-based technique because it involves the tester using their experience to identify potential errors or faults in the system. The fault attack, mentioned in statement III, is a structured approach to "error guessing," indicating that it is a specific technique within the broader category of experience-based techniques. Exploratory testing, mentioned in statement IV, is also an experience-based technique that is particularly useful when the specifications are complete and there is no time pressure. Therefore, the correct statements are I and III.

Which of the following statements is true? Select one:
- A.
  
  It is impossible to achieve 100% statement coverage
- B.
  
  100% statement coverage means 100% branch coverage
- C.
  
  100% branch coverage means 100% statement coverage and vice versa
- D.
  
  100% branch coverage means 100% statement coverage
Correct Answer
D. 100% branch coverage means 100% statement coverage

Explanation
100% branch coverage means 100% statement coverage because branch coverage refers to the percentage of branches in the code that have been executed, while statement coverage refers to the percentage of statements in the code that have been executed. Since every branch contains at least one statement, achieving 100% branch coverage implies that every statement in the code has been executed, resulting in 100% statement coverage as well. Therefore, the two terms are equivalent in this context.

Which of the following is NOT an example of dynamic testing? Select one:
- A.
  
  Code inspection
- B.
  
  Checking memory leaks for a program by executing it
- C.
  
  Coverage analysis
- D.
  
  Testing for performance
Correct Answer
A. Code inspection

Explanation
Dynamic testing refers to testing techniques that involve executing the code and observing its behavior. It focuses on evaluating the software's functionality, performance, and reliability during runtime. Code inspection, on the other hand, is a static testing technique that involves reviewing the code without executing it. It aims to identify defects, improve code quality, and ensure adherence to coding standards. Since code inspection does not involve executing the code, it is not an example of dynamic testing.

Which are the MAIN goals of risk management in a software project? Select one:
- A.
  
  To control contractual problems and minimize the impacts of company policies
- B.
  
  To increase focus on preventative processes and to increase satisfaction for the testers
- C.
  
  To increase the success probability for the project regardless of costs
- D.
  
  To reduce the probability of undesired situations and to reduce the effect of potential impact
Correct Answer
D. To reduce the probability of undesired situations and to reduce the effect of potential impact

Explanation
The main goals of risk management in a software project are to reduce the probability of undesired situations and to reduce the effect of potential impact. This means identifying and assessing potential risks, implementing strategies to mitigate or avoid them, and monitoring and controlling risks throughout the project lifecycle. By doing so, the project team can minimize the likelihood of negative events occurring and minimize the impact if they do occur, ultimately increasing the chances of project success.

You have to specify test cases based on equivalence partitioning and boundary value analysis for an internet shop selling baby shoes. The shop provides a selection of shoes based on the following input parameters. There are 4 different sizes, depending on the age of the baby. The system selects the appropriate size based on the following criteria: 1. 0 < age <= 4 months: size 1 2. 4 < age <= 8 months: size 2 3. 8 < age <= 15 months: size 3 4.15 < age <= 24 months: size 4 The gender of the baby: boy or girl Which of the following statements is true? Select one:
- A.
  
  There are two invalid equivalence classes for the age input parameter
- B.
  
  The total number of combinations of valid equivalence classes of age and gender is 8
- C.
  
  All valid equivalence classes could be covered with 6 test cases
- D.
  
  All combinations of valid equivalence classes could be covered with 4 test cases
Correct Answer
B. The total number of combinations of valid equivalence classes of age and gender is 8

Explanation
The correct answer is "The total number of combinations of valid equivalence classes of age and gender is 8." This is because there are 4 different sizes based on the age of the baby and 2 options for the gender of the baby. Therefore, the total number of combinations is 4 (age) * 2 (gender) = 8.

Which of the following statements correctly describe Black box testing? Select one:
- A.
  
  Test of the interfaces between components and of the interactions with different parts of a system
- B.
  
  Test on an individual software component in isolation from other components, to avoid external influence
- C.
  
  Tests that investigate the input vs. the output behavior of a software system
- D.
  
  Test derived from the ability of the testers and their intuition and experience with similar applications and technologies sometimes used to strengthen systematic techniques)
Correct Answer
C. Tests that investigate the input vs. the output behavior of a software system

Explanation
Black box testing is a method of software testing where the internal workings of the system being tested are not known to the tester. It focuses on testing the behavior of the system based on its inputs and outputs. This means that the tester does not need to know the internal code or structure of the system, but rather focuses on testing the functionality and correctness of the system's response to different inputs. Therefore, the statement "Tests that investigate the input vs. the output behavior of a software system" correctly describes Black box testing.
