Deselect Answer

Question #19 (1 Point)

Which of the following statements BEST describes the difference between decision table testing and branch testing?Deselect Answer

Question #20 (1 Point)

Customers of the TestWash car wash chain have cards with a record of the number of washes they have bought so far. The initial value is 0. After entering the car wash, the system increases the number on the card by one. This value represents the number of the current wash. Based on this number the system decides what discount the customer is entitled to.

For every tenth wash the system gives a 10% discount, and for every twentieth wash, the system gives a further 40% discount (i.e., a 50% discount in total).

Which of the following sets of input data (understood as the numbers of the current wash) achieves the highest equivalence partition coverage?Deselect Answer

Question #21 (1 Point)

You are testing a form that verifies the correctness of the length of the password given as input. The form accepts a password with the correct length and rejects a password that is too short or too long. The password length is correct if it has between 6 and 12 characters inclusive. Otherwise, it is considered incorrect.

At first, the form is empty (password length = 0). You apply boundary value analysis to the “password length” variable.

Your set of test cases achieves 100% 2-value boundary value coverage. The team decided that due to the high risk of this component, test cases should be added to ensure 100% 3-value boundary value coverage.

Which additional password lengths should be tested to achieve this?Deselect Answer

Question #22 (1 Point)

The following decision table contains the rules for determining the risk of atherosclerosis.

You designed the test cases with the following test input data:

What is the decision table coverage achieved by these test cases?
Deselect Answer

Question #23 (1 Point)

Which of the following test cases, represented as sequences of events, achieves the highest level of valid transitions coverage?
Deselect Answer

Question #24 (1 Point)

You run two test cases, T1 and T2, on the same code. Test T1 achieved 40% statement coverage and test T2 achieved 65% statement coverage.

Which of the following sentences must be necessarily true?Deselect Answer

Question #25 (1 Point)

The estimated development effort for the new project is $800,000. What is your estimate of the test effort in this project?
Deselect Answer

Question #32 (1 Point)

You are testing a web application that allows users to SEARCH for products, VIEW product details, ADD products to a shopping cart, and place an ORDER.

You have prepared the following five test cases, which you want to execute according to their priorities:

You also identified the following logical dependencies between test cases:

  • SEARCH functionality must be tested before VIEW functionality can be tested, as product details rely on search functionality.
  • VIEW functionality must be tested before ADD functionality, as adding products relies on the availability of accurate product details.
  • ADD functionality must be tested before ORDER functionality, as placing an order relies on the availability of accurate shopping cart information.
