Question No. 1

Which of the statements correctly describes when a whole team approach may NOT be suitable?

Show Answer Hide Answer
Correct Answer: A

The whole team approach involves collaboration among all team members, including testers, developers, and business representatives, to achieve quality goals. However, this approach may not be suitable in situations where a high level of test independence is required. Test independence is essential in cases where unbiased testing is critical, such as in regulated environments or where high-risk systems are involved. This is because team members might unintentionally influence each other's work, leading to potential bias in testing outcomes.


Question No. 3

A requirement specifies that a certain identifier (ID) must be between 5 and 10 characters long, must contain only alphanumenc characters, and its first character must be a letter As a tester, you want to apply one-dimensional equivalence partitioning to test this ID. This means that you have to apply equivalence partitioning individually: to the length of the ID, the type of characters contained within the ID, and the type of the first character of the ID. What is the number of partitions to cover?

Show Answer Hide Answer
Correct Answer: A

To apply one-dimensional equivalence partitioning to the ID requirement, we need to consider each condition individually:

Length of the ID: Valid partitions (5-10 characters), Invalid partitions (less than 5, more than 10) = 3 partitions.

Type of characters: Valid partitions (alphanumeric), Invalid partitions (non-alphanumeric) = 2 partitions.

First character: Valid partitions (letter), Invalid partitions (non-letter) = 2 partitions. Adding these partitions, we get a total of 3 (length) + 2 (character type) + 2 (first character) = 7 partitions. Thus, the correct answer is A.


Question No. 4

Given the following User Story: "As an online customer, I would like to be able to cancel the purchase of an individual item from a shopping list so that it only displays the relevant items, in less than 1 second", which of the following can be considered as applicable acceptance test cases?

I . Click on my online shopping list, select the unwanted Item, delete the unwanted item, the unwanted Item is deleted from the shopping list in less than 1 second.

Ii . Click on my online shopping list, select all the items, delete all the items, the unwanted items are deleted from the shopping list in less than 1 second.

Iii . Tab to the online shopping list and press enter, select the unwanted item, delete the unwanted item, the unwanted item is deleted from the shopping list In less than 1 second.

Iv . Click on the checkout button, select the payment method, make payment, confirmation received of payment and shipping date.

V . Click on my shopping list, select the unwanted Item, delete the unwanted item, the unwanted item is deleted from the shopping list.

Select the correct answer:

Show Answer Hide Answer
Correct Answer: C

Applicable acceptance test cases for the given user story should focus on the specific requirement of deleting an individual item from the shopping list and ensuring that it is removed in less than 1 second. Therefore, the valid test cases are: i. Click on my online shopping list, select the unwanted item, delete the unwanted item, the unwanted item is deleted from the shopping list in less than 1 second. iii . Tab to the online shopping list and press enter, select the unwanted item, delete the unwanted item, the unwanted item is deleted from the shopping list in less than 1 second.

Question No. 5

Which of the following issues cannot be identified by static analysis tools?

Show Answer Hide Answer
Correct Answer: A

Static analysis tools are software tools that examine the source code of a program without executing it.They can detect various types of issues, such as syntax errors, coding standards violations, security vulnerabilities, and potential bugs12.However, static analysis tools cannot identify issues that depend on the runtime behavior or performance of the program, such as very low MTBF (Mean Time Between failure)3. MTBF is a measure of the reliability of a system or component. It is calculated by dividing the total operating time by the number of failures. MTBF reflects how often a system or component fails during its expected lifetime. Static analysis tools cannot measure MTBF because they do not run the program or observe its failures.MTBF can only be estimated by dynamic testing, which involves executing the program under various conditions and collecting data on its failures4. Therefore, very low MTBF is an issue that cannot be identified by static analysis tools. The other options, such as potentially endless loops, referencing a variable with an undefined value, and security vulnerabilities, are issues that can be identified by static analysis tools.Static analysis tools can detect potentially endless loops by analyzing the control flow and data flow of the program and checking for conditions that may never become false5.Static analysis tools can detect referencing a variable with an undefined value by checking the scope and initialization of variables and reporting any use of uninitialized variables6. Static analysis tools can detect security vulnerabilities by checking for common patterns of insecure code, such as buffer overflows, SQL injections, cross-site scripting, and weak encryption.Reference=What Is Static Analysis?
