QUESTION 11

QUESTION 13
Your agile project has scheduled a final sprint before release to fix and re-test all open defects with a priority level of 3 or above.
The following defect report shows the defect fields that are currently being captured on the system.
Title: Unable to add excursions to pre-paid cruises
Date raised: 21/05/18
Author: Emma Rigby
Status: Fixed
What occurred: I went to book an excursion for a pre-paid cruise but received an error message saying,
‘Facility not available’. I can book excursions on cruises that have not yet been fully paid.
What should have occurred: Requirement 3.12 says clearly that customers can add excursions after cruises have been fully paid so the facility should have been available (when an additional amount may now need to be paid).
Priority: 2
Software build: 2.1
Test level: System test
Environment details: System test 3
Which of ONE of the following additional defect report fields would be MOST beneficial for the sprint team to add?

Severity.

Test Script Id.

Actual results.

Expected results.

QUESTION 14
Which of the following is an approach that can be used for exploratory testing?

Time-boxed test sessions are created, during which a tester uses a test charter containing test objectives to guide the testing.

A tester analyses, designs and implements tests based on external rules and standards.

Tests are designed based on the guidance of stakeholders and experts outside the test team.

QUESTION 15
Which of the following is NOT a valid use of decision coverage?

Checking that all decisions have been exercised in a single program.

Checking that all decisions have been exercised in a business process.

Checking that all decisions are based on a numeric value.

Checking that at least 100% decision coverage has been achieved, as this guarantees 100% statement coverage.

QUESTION 16
Tests have been specified for the latest software release and users have prioritised these.

Which test execution schedule best meets the prioritisation and dependency conditions?

3, 5, 7, 10, 2, 4, 6, 8, 9, 1.

5, 7, 4, 3, 9, 10, 1, 6, 8, 2.

6, 1, 2, 9, 4, 3, 5, 7, 8, 10.

1, 4, 3, 5, 2, 7, 9, 10, 6, 8.

QUESTION 17
Which of the following is a key difference between black box and white box test design techniques?

Black box techniques use software code to derive test cases, white box techniques do not.

White box techniques use functional design specifications to derive test cases, black box techniques do not.

White box techniques can measure the extent of code coverage, black box techniques can not.

White box techniques derive test cases from models of the software, black box techniques do not.

QUESTION 18
Which of the following BEST describes a methodical approach to the Error Guessing test technique?

A tester dynamically designs and executes tests based on their knowledge, exploration of the test item and the results of previous tests.

An experienced tester makes a list of potential defects and failures, and designs and runs tests to generate these failures should the defects be present in the code.

A tester designs, implements and executes tests to cover test conditions found in checklists that are based on what is important for the user.

An inexperienced tester is asked to attempt to guess errors that may have been missed by experienced testers during formal test design.

QUESTION 19
Which of the following would achieve the HIGHEST level of testing independence for a project’s system test level?

Training developers to design good tests for the test team to execute.

Outsourcing test design and execution to a different company.

Having the company’s independent test team design and execute the tests.

Minimising contact between testers and developers during test design to avoid bias.

QUESTION 20
Which of the following BEST describes a Test Case?

A statement about “what to test” in terms of measurable coverage criteria from analysis of the test basis.

A set of preconditions, inputs, actions, expected results and postconditions developed based on test conditions.

A description of the test objectives to be achieved and the means and the schedule for achieving them.

A source to determine expected results to compare with the actual result of the system under test.

QUESTION 21
A holiday club restricts those booking the holiday, to people between the ages of 18 and 30 inclusive.
Using three-point boundary values, what ages would be required to test the lower and upper boundary?

17, 18, 19, 29, 30, 31.

17, 18, 19, 30, 31, 32.

18, 19, 20, 28, 29, 30.

QUESTION 22
A car insurance policy has 3 rates of insurance depending on the age of the driver. For drivers aged between
17 and 25 inclusive they are charged at rate A, drivers aged between 26 and 50 inclusive are charged at rate B and those drivers aged over 50 are charged at rate C.
You are designing test cases, which of the following three ages would test all valid equivalence partitions and therefore test rate A, B and C?

26, 45, 50.

10, 21, 55.

20, 35, 65.

QUESTION 23
Which of the following options BEST explains the pesticide paradox principle of testing?

If we do not regularly review and revise our tests, we’ll stop finding defects.

Repeatedly running a set of tests will ensure that a system is defect free.

Defects are, paradoxically, often contained in a small number of modules.

Testing, like spraying pesticide, is an effective bug/defect removal activity.

QUESTION 24
Which statement about deriving test cases from a use case is TRUE?

There should only be one test case for each use case.

Test cases can only be derived if there is an activity diagram.
