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 development is also done in cycles consisting of the same activities in every increment
B
Because in each increment, the test analyst is involved as soon as the development begins
C
Because the activities of the test analyst in each increment are limited to test analysis and test design
D
Because each increment develops a new part of the software, which needs to be tested

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 bank account validation using both photo-based and manually entered invoice payments
B
Execute all regression tests for the settlement of payments and other features related to balance calculations
C
Execute at least one regression test for each requirement, prioritizing the most frequently used scenarios
D
Execute all regression tests with a critical or major risk impact of potential failures
Correct Answer:
A :
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?

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?

You test a food ordering scenario based on the following use case:
1. The customer opens the application and logs in. 2. The customer browses the menu and selects items to order. 3. The customer adds selected items to the cart. 4. The customer proceeds to the checkout. 5. The application displays the order summary, including items, quantities, and total price. 6. The customer confirms the order. 7. The application asks if the saved payment method should be used. 8. The customer confirms the saved payment method. 9. The application processes the payment. 10. The application sends a confirmation notification to the customer. 11. The application forwards the order to the restaurant. 12. The application updates the order status to "Confirmed". Alternative scenarios: 4A. The customer goes back to browsing the menu. The scenario goes back to step 2. 6A. The customer goes back to browsing the menu. The scenario goes back to step 2. 7A. No payment method is saved. The system asks for the credit card details. The customer fills in the data. The scenario goes to step 9. 7B. More than one payment method is saved. The system asks the customer to select one of the payment methods. The scenario goes to step 9. Exceptions: 9A. The payment process fails. The system informs the customer about the error. The use case ends. The adopted test strategy requires testing the main scenario and all of the alternatives and exceptions. The test strategy allows more than one alternative to be tested within a single test case. However, it is forbidden to create test cases in which both an alternative and an exception would occur (i.e., if an exception occurs in a test case, no alternative can occur in it). What is the MINIMUM number of test cases that will cover all the scenarios for this use case?
