ISQI ISTQB Certified Tester Foundation Level (CTFL) v4.0 Sample Questions (Q150-Q155):

NEW QUESTION # 150
Calculate the measurement error SD for the following estimates done using three point estimation technique- Most optimistic effort (a) -120 person days Most likely effort (m) -180 person days Most pessimistic effort (b) - 240 person days

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A

Explanation:
A test-first approach involves writing tests before writing the code. In this approach, initially, the tests fail because the corresponding functionality is not yet implemented. Afterward, the code is written or modified to make the tests pass. This cycle is repeated iteratively. This method ensures that the code is developed based on predefined tests and helps in identifying issues early in the development process.


NEW QUESTION # 151
A company runs a pilot project for evaluation of a test automation tool. Which of the following is NOT a valid object of this pilot project?

  • A. Decide upon standards for tool implementation
  • B. Check haw the tool fits to the existing test processes
  • C. Train all testers on using the tool
  • D. Get familiar with the functionality and options of the tool

Answer: C

Explanation:
* A pilot project is a small-scale experiment or trial that is conducted to evaluate the feasibility, effectiveness, and suitability of a test automation tool before implementing it on a larger scale1.
* The objectives of a pilot project may vary depending on the context and scope of the test automation initiative, but some common ones are2:
* To get familiar with the functionality and options of the tool
* To check how the tool fits to the existing test processes and environment
* To assess the benefits and challenges of using the tool
* To decide upon standards and guidelines for tool implementation and usage
* To estimate the costs and resources required for tool deployment and maintenance
* Therefore, option C is not a valid objective of a pilot project, as it is not necessary to train all testers on using the tool at this stage. Training all testers on using the tool would be more appropriate after the tool has been selected and approved for full-scale implementation, and after the standards and guidelines have been established. Training all testers on using the tool during the pilot project would be inefficient, costly, and premature, as the tool may not be suitable or effective for the intended purpose, or may be replaced by another tool later.

NEW QUESTION # 152
A typical generic skill required for the role of tester is the ability to:

  • A. assume leadership aimed at imposing decisions on the rest of the team
  • B. determine the corrective actions to get a test project on track in case of deviations from the test plan
  • C. take on the role of developer to meet challenging project deadlines
  • D. use tools to make the execution of repetitive testing tasks more efficient

Answer: D

Explanation:
One of the generic skills required for the role of a tester is the ability to use tools to make the execution of repetitive testing tasks more efficient. This includes using various test automation tools to streamline the testing process, reduce manual effort, and improve the consistency and accuracy of test results. Testers should be proficient in leveraging these tools to enhance productivity and ensure comprehensive test coverage.

NEW QUESTION # 153
An alphanumeric password must be between 4 and 7 characters long and must contain at least one numeric character, one capital (uppercase) letter and one lowercase letter of the alphabet.
Which one of the following sets of test cases represents the correct outcome of a two-value boundary value analysis applied to the password length? (Note: test cases are separated by a semicolon)

  • A. 1xB: aB11: 99rSp: 5NnN10; 4NnN10T; 44ghWn19
  • B. aB11;99rSp:5NnN10;7iDD0a1x
  • C. 1xA;aB11;Pq1ZZab;7iDD0a1x
  • D. 1RhT;rSp53;3N3e10;8sBdby

Answer: D

Explanation:
Explanation
The correct outcome of a two-value boundary value analysis applied to the password length is the set of test cases represented by option D. Boundary value analysis is a test design technique that focuses on the values at the boundaries of an equivalence partition, such as the minimum and maximum values, or the values just above and below the boundaries. A two-value boundary value analysis uses two values for each boundary, one representing the valid value and one representing the invalid value. For example, if the valid range of values is from 4 to 7, then the two values for the lower boundary are 3 and 4, and the two values for the upper boundary are 7 and 8. The test cases in option D use these values for the password length, while also satisfying the other requirements of the password, such as containing at least one numeric character, one capital letter, and one lowercase letter. The test cases in option D are:
1RhT: a 4-character password that is valid
rSp53: a 5-character password that is valid
3N3e10: a 6-character password that is valid
8sBdby: an 8-character password that is invalid The test cases in the other options are incorrect, because they either use values that are not at the boundaries of the password length, or they do not meet the other requirements of the password. For example, the test cases in option A are:
1xA: a 3-character password that is invalid, but it does not contain a capital letter aB11: a 4-character password that is valid Pq1ZZab: a 7-character password that is valid
7iDD0a1x: an 8-character password that is invalid References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

NEW QUESTION # 154
A requirement specifies that if the total amount of sales (TAS) made during the year by a corporate seller is
300000€ or more, the bonus that must be paid to the seller is 100% of a certain amount agreed upon at the beginning of the year. The software contains a fault as it implements this requirement with the decision "IF (TAS = 300000)" instead of "IF (TAS >= 300000)". The application of the 3-value boundary value analysis to this problem consists of the following three test cases (TAS is an integer variable):
TC1 = 299999 TC2=300000 TC3=300001
Which of the following statements is true?

  • A. TC1 would highlight the fault
  • B. TC2 would highlight the fault
  • C. TC3 would highlight the fault
  • D. None of the three test cases would highlight the fault

Answer: C

Explanation:
The problem described involves a software implementation error in a decision statement for calculating a bonus based on the Total Amount of Sales (TAS). The requirement states that if TAS is 300,000€ or more, a bonus should be paid. However, the software incorrectly implements this with "IF (TAS = 300000)" instead of
"IF (TAS >= 300000)".
Applying Boundary Value Analysis (BVA) to this situation involves selecting test cases at the boundaries of the input domain, including just below, at, and just above the boundary conditions.
* Test Case TC1 = 299999:
* This value is just below the boundary (300,000).
* Expected Result: No bonus should be paid.
* Actual Result: No bonus paid.
* TC1 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (no bonus).
* Test Case TC2 = 300000:
* This value is exactly at the boundary.
* Expected Result: Bonus should be paid.
* Actual Result: Bonus paid.
* TC2 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (bonus paid).
* Test Case TC3 = 300001:
* This value is just above the boundary.
* Expected Result: Bonus should be paid.
* Actual Result: No bonus paid due to the incorrect implementation.
* TC3 highlights the fault because the implemented condition "IF (TAS = 300000)" fails to pay the bonus, whereas the correct condition "IF (TAS >= 300000)" would pay the bonus.
* BVA focuses on the edges of input ranges where errors are more likely.
* The critical values are just below, at, and just above the boundary.
Boundary Value Analysis (BVA):Verification:According to the ISTQB CTFL syllabus, BVA is an essential technique for identifying potential errors at the boundaries of input ranges. This is because developers are more likely to make mistakes at these extremes.
Therefore, TC3 (300001) is the test case that would highlight the fault in the software's implementation of the decision condition.
