Your organization is implementing a food ordering application intended to feature an intuitive user interface (easy navigation and quick search) and offering functions such as: personalization of the order (option to modify ingredients, comments for the restaurant) verification of the correctness of the order before it is sent real-time order tracking view order history You analyze a four-point checklist for functional testing that was prepared by another test analyst.
Which of these points is NOT a good example of an item for this checklist?
- A . When the user enters the order history, does the system show recent orders?
- B . Does the system allow customers to rate meals and restaurants?
- C . Does the system validate the client’s address before accepting the order?
- D . Does the system allow adding a comment for the restaurant to an order?

A credit risk scoring system receives two integers, L and E, as input, representing credit scores calculated by two independent systems.
The system evaluates credit risk according to the following business logic:
IF L >= 50 OR E >= 50 THEN the risk is high
IF L <= 49 AND E <= 49 THEN the risk is low
The figure shows a section of the input domain. The points in the gray area belong to the equivalence partition “high risk,” and the points outside it belong to the equivalence partition “low risk.” The lines represent the closed border of the “high risk” equivalence partition.
You apply domain-based testing to verify the correct implementation of the above requirement. The test set includes the five points marked in black in the figure: (L=48, E=48), (L=49, E=49), (L=49, E=50), (L=50, E=49), and (L=54, E=53).
What level of RELIABLE domain coverage does the test set of these points achieve?
- A . 50%
- B . 62.5%
- C . 87.5%
- D . 100%

What is an example of a risk associated with automated test design?
- A . Omission of important test conditions from the software model
- B . High cost of test execution due to software changes
- C . Difficulty in analyzing the results of the automated test execution
- D . Reduction of repetitive work involving manual test specification
You are testing a beverage vending machine. The beverage price is $1. The machine accepts coins with denominations of 25c, 50c, and $1. When the sum of the coins inserted equals or exceeds the beverage price, the system dispenses the beverage and returns the change. However, if the system is unable to dispense change due to a lack of coins or the user presses the cancel button, the system does not dispense the beverage and returns the inserted coins.
You use a keyword-based approach. You have the following keywords at your disposal.
Consider the following test script written using keywords to execute a certain test scenario.
DefineState(1,1,1)
Insert25
Cancel
Insert50
Insert50
What keyword should this test script end with?
- A . VerifyState(2.75).
- B . VerifyState(1.75).
- C . VerifyState(1.25).
- D . VenfyState(3.00).
What is an example of FUNCTIONAL CORRECTNESS testing of a food ordering app?
- A . Testing the adaptation of the user interface for visually impaired users
- B . Testing the allocation of discounts depending on the number of purchases
- C . Testing whether the social media login function has been implemented in the system
- D . Testing whether a group order requires fewer steps than a regular order
Your regression test suite includes five test cases, TC1-TC5.
They cover the use case scenarios UC1-UC10 as follows:
TC1 covers UC1, UC2, UC3, UC4, UC5, UC6, UC7, UC8
TC2 covers UC7, UC8
TC3 covers UC2, UC4, UC6, UC7
TC4 covers UC10
TC5 covers UC5, UC8, UC9
The system consists of three components: C1, C2, and C3.
C1 implements scenarios UC1, UC2, UC3, UC4;
C2 implements scenarios UC5, UC6, UC7;
C3 implements scenarios UC8, UC9, UC10.
The latest iteration of the project refactored the C3 component. Your organization uses a regression test selection strategy based on scenario coverage.
Due to time constraints, you only have time to execute two regression tests.
Which TWO test cases should be executed? (Choose two.)
- A . TC1
- B . TC2
- C . TC3
- D . TC4
- E . TC5
Your organization produces a computer game tested at four major stages: requirements review, architecture review, component implementation, and component integration. One year after the game’s release, you analyze data on the number of defects reported.
You are analyzing the efficiency of development phases using the Defect Detection Percentage (DDP) metric. You want to identify the phase with the lowest DDP so that you can introduce activities that will improve defect detection.
Which phase has the lowest DDP?
- A . Architecture review
- B . Requirements review
- C . Component implementation
- D . Component integration
Your organization is implementing a food ordering application intended to feature an intuitive user interface (easy navigation and quick search) and offering functions such as: personalization of the order (option to modify ingredients, comments for the restaurant) verification of the correctness of the order before it is sent real-time order tracking view order history. Management decided to test the requirements mentioned above using a checklist and has asked you to prepare this.
Consider the following four checklists.
Checklist 1
[ ] Does the system reject an order with an incorrect zip code?
[ ] Does the system reject an order with an unfilled mandatory field?
Checklist 2

The search function allows the user to quickly search for restaurants (YES / NO / PARTIALLY)
Checklist 3
[ ] Is the time from order placement to order confirmation less than 10s?
[ ] Is the user interface free of grammatical errors?
