NEW QUESTION # 181
Consider the following user story about an e-commerce website's registration feature that only allows registered users to make purchases ; As a new user, I want to register to the website, so that I can start shopping online" The following are some of the acceptance criteria defined for the user story
[a] The registration form consists of the following fields: username, email address, first name, last name, date of birth, password and repeat password.
[b] To submit the registration request, the new user must fill in all the fields of the registration form with valid values and must agree to the terms and conditions.
[c] To be valid, the email address must not be provided by free online mail services that allow to create disposable email addresses. A dedicated error message must be presented to inform the new user when an invalid address is entered.
[d] To be valid, the first name and last name must contain only alphabetic characters and must be between 2 and 80 characters long A dedicated error message must be presented to inform the new user when an invalid first name and/or the last name is entered
[e] After submitting the registration request, the new user must receive an e-mail containing the confirmation link to the e-mail address specified in the registration form Based only on the given information, which of the following ATDD tests is MOST LIKELY to be written first?
Answer: D
Explanation:
Acceptance Test-Driven Development (ATDD) tests focus on verifying whether the system meets the specified acceptance criteria. The most critical path to test first would be the scenario where everything is done correctly (happy path), ensuring the basic functionality works as expected.
The new user provides all valid data.
This ensures the registration form works and the user receives a confirmation email.
This test covers the basic functionality and will help verify that the primary use case is handled correctly before testing invalid or edge cases.
NEW QUESTION # 182
For the same financial institution in Question 12, with the same requirements and expectations, what would be the most likely investment values used in testing if two-point boundary value analysis is used to design test cases specific to the 13% interest rate equivalence partition?
Answer: D
Explanation:
For boundary value analysis, the test cases should include the boundary values just inside and just outside the equivalence partition for the 13% interest rate range:
R100,000 (just inside the previous range)
R100,001 (start of the 13% range)
R500,000 (end of the 13% range)
R500,001 (just outside the range)
These values ensure that both the edges of the partition are tested.
NEW QUESTION # 183
Mark the correct sentences:
* Defects are a result of environmental conditions and are also referred to as "Failures"
* A human mistake may produce a defect
* A system mil totally fail to operate correctly when a failure exists in it
* When a defect exists in a system it may result in a failure
* Defects occur only as a result of technology changes
Answer: A
Explanation:
The question is about marking the correct sentences among the given statements related to defects, failures, and mistakes. According to the ISTQB glossary, the definitions of these terms are1:
Defect: A flaw in a component or system that can cause the component or system to fail to perform its required function, e.g. an incorrect statement or data definition. A defect, if encountered during execution, may cause a failure of the component or system.
Failure: An event in which a component or system does not perform a required function within specified limits.
Mistake: A human action that produces an incorrect result.
Therefore, out of the five given statements, only two are correct, namely:
A human mistake may produce a defect: This is true, as a mistake is a source or cause of a defect, e.g. a programmer may make a mistake in writing a code statement, which results in a defect in the software component.
When a defect exists in a system it may result in a failure: This is true, as a defect is a potential or actual cause of a failure, e.g. a defect in the software component may cause the system to fail to perform a required function when the defect is encountered during execution.
The other three statements are incorrect, namely:
Defects are a result of environmental conditions and are also referred to as "Failures": This is false, as defects are not a result of environmental conditions, but of mistakes or other factors, and defects are not the same as failures, but rather the causes of failures.
A system will totally fail to operate correctly when a failure exists in it: This is false, as a system may not necessarily fail completely or stop operating when a failure occurs, but may continue to operate with reduced functionality or performance, or with incorrect results.
Defects occur only as a result of technology changes: This is false, as defects can occur due to various reasons, not only technology changes, such as human mistakes, design flaws, requirement changes, hardware failures, etc.

NEW QUESTION # 184
What is test oracle?
Answer: D
Explanation:
A test oracle is a mechanism or principle that can be used to determine whether the observed behavior or output of a system under test is correct or not1. A test oracle can be based on various sources of expected results, such as specifications, user expectations, previous versions, comparable systems, etc2. References:

NEW QUESTION # 185
Which ONE of the following options MOST ACCURATELY describes the activities of "testing" and
"debugging"?
Answer: D
Explanation:
Comprehensive and Detailed In-Depth Explanation:Testing and debugging are separate but related activities. Testing executes the software to identify failures that result from defects (A). Debugging is the developer's responsibility and involves finding the cause of a failure (defect), analyzing it, and fixing the defect. The ISTQB syllabus explicitly differentiates these activities. Testing does not modify the software, whereas debugging does.
