Q1:
Chapter: 1 - The Tasks of the Test Analyst in the Test Process
Why does a test analyst carry out the same activities in every increment of an incremental development model?
A
Because the activities of the test analyst in each increment are limited to test analysis and test design
B
Because development is also done in cycles consisting of the same activities in every increment
C
Because in each increment, the test analyst is involved as soon as the development begins
D
Because each increment develops a new part of the software, which needs to be tested
Correct Answer:
D :
Because each increment develops a new part of the software, which needs to be tested

You are given traceability information about the implemented functions (F1-F5), identified risks (R1-R5), and regression test cases (TC1-TC6) in the form of the following traceability matrices (see table)
You also have the following information about the risk levels for all of the identified risks (see risks table) All six test cases were executed in the last test cycle. Then, you are informed that the implementation of F3 has changed.

Chapter: 2 - The Tasks of the Test Analyst in Risk-Based Testing
You are system-testing a mobile banking application.
The development is divided between a backend team that designs the business logic on the servers and a frontend team that designs the graphical user interface (GUI) and the application on the mobile devices. The backend team is experienced and can debug and resolve defects quickly and reliably. The frontend team has undergone a lot of staff turnover. Recently, critical failures occurred in production and were resolved in the previous release: • Payments rejected by the destination banks due to invalid bank account numbers. The root cause was insufficient validation of bank accounts in the mobile devices. • Incorrectly displayed GUI elements on some screen sizes and resolutions that obstructed users when entering payments. The next release will contain the following changes: • A new feature was added that allows users to make payments by taking a photo of an invoice with their mobile device. • A major defect in the calculation of the account balance was fixed. • The navigation bar in the GUI was redesigned to comply with accessibility standards. You have a comprehensive regression test suite with tests categorized by the impact of potential failures. Due to limited testing resources, you cannot execute them all, so you chose the history-based regression testing strategy. Which of the following test objectives suits this scenario THE BEST?
A
Execute all regression tests for the settlement of payments and other features related to balance calculations
B
Execute at least one regression test for each requirement, prioritizing the most frequently used scenarios
C
Execute all regression tests for the bank account validation using both photo-based and manually entered invoice payments
D
Execute all regression tests with a critical or major risk impact of potential failures
Correct Answer:
C :
Execute all regression tests for the bank account validation using both photo-based and manually entered invoice payments

A code complexity evaluation system takes two integers as input, representing the cyclomatic complexity
(CC) and the number of variables in the code (VAR). The system checks whether the code is complex based on the following model: IF (CC ≥ 10) AND (VAR ≥ 8) THEN RETURN “the code is complex” The domain determined by the intersection of the above two borders is a set of points in two-dimensional space with integer coordinates (CC, VAR). You want to test the functional correctness of the implementation of this domain using domain testing. Which set of test points could result from using the SIMPLIFIED domain coverage to test the correctness of this domain implementation?
A

Chapter: 3 - Test Analysis and Test Design
The requirements for brewing espresso are:
• The pressure shall be at least 9 bars for ideal extraction. • The temperature shall be at least 90°C and at most 96°C to prevent under-extracting or burning coffee. You test the software controller that opens the hot water valve when pressure (P) and temperature (T) are in the right range (i.e., P≥9 AND T≥90 AND T≤96) and shuts it otherwise (i.e., P<9 OR T<90 OR T>96). The barometer measures the pressure with a precision of 0.1 bar; the thermometer works with a precision of 0.5°C. Your test suite executes the controller with the following inputs (P, T) of pressure in bar and temperature in degrees Celsius: A = (9, 90) B = (9, 96) C = (8.9, 93) D = (10, 96.5) E = (10, 93) F = (8, 89) G = (10, 98) Which of the following inputs is missing for 100% reliable domain coverage?
