  4. developers would typically use ii, iv and vi; test team I, ii and v

Show answer
Correct Option: B

The main focus of acceptance testing is:

technology testing

  1. finding faults in the system

  2. ensuring that the system is acceptable to all users

  3. testing the system with other systems

  4. testing for a business perspective

Show answer
Correct Option: D

Which of the following statements about the component testing standard is false:

  2. white box design techniques all have an associated measurement technique

  3. black box measurement techniques all have an associated test design technique

  4. white box measurement techniques all have an associated test design technique

Show answer
Correct Option: A

Which of the following statements is NOT true:

technology testing

  1. inspection is the most formal review process

  2. inspections should be led by a trained leader

  3. managers can perform inspections on management documents

  4. inspection is appropriate even when there are no written documents

Show answer
Correct Option: D

AI Explanation

To answer this question, you need to understand the concept of inspections and review processes. Let's go through each option to understand why it is correct or incorrect:

Option A) Inspection is the most formal review process - This option is incorrect. Inspections are a type of review process, but they are not necessarily the most formal. Other review processes, such as audits, can be more formal depending on the context.

Option B) Inspections should be led by a trained leader - This option is correct. Inspections should be led by a trained leader who is familiar with the inspection process and can effectively guide the team through the review.

Option C) Managers can perform inspections on management documents - This option is correct. Managers can perform inspections on management documents as part of the review and quality assurance processes.

Option D) Inspection is appropriate even when there are no written documents - This option is incorrect. Inspections typically involve the review of written documents, such as code, designs, or specifications. Without written documents, there would be nothing to inspect.

The correct answer is D. This option is incorrect because inspections require written documents to review and inspect.

A typical commercial test execution tool would be able to perform all of the following EXCEPT:

technology testing

  1. generating expected outputs

  2. replaying inputs according to a programmed script

  3. comparison of expected outcomes with actual outcomes

  4. recording test inputs

Show answer
Correct Option: A

The difference between re-testing and regression testing is

technology testing

  1. re-testing is running a test again; regression testing looks for unexpected side

  2. re-testing looks for unexpected side effects; regression testing is repeating

  3. re-testing is done after faults are fixed; regression testing is done earlier

  4. re-testing uses different environments, regression testing uses the same

Show answer
Correct Option: A

Expected results are:

technology testing

  1. only important in system testing

  2. only used in component testing

  3. most useful when specified in advance

  4. derived from the code

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of expected results in software testing.

Expected results are the predicted outcomes or behavior of a system or component under test. They are typically determined in advance based on the requirements or specifications of the system.

Let's go through each option to understand why it is correct or incorrect:

Option A) only important in system testing - This option is incorrect because expected results are important in all types of testing, not just system testing.

Option B) only used in component testing - This option is incorrect because expected results are used in all types of testing, not just component testing.

Option C) most useful when specified in advance - This option is correct because expected results are most useful when they are specified in advance. By defining the expected results before the testing phase, testers can compare the actual results with the expected results to determine if the system or component is functioning correctly.

Option D) derived from the code - This option is incorrect because expected results are not derived from the code itself. They are determined based on the requirements or specifications of the system, not the code.

The correct answer is C) most useful when specified in advance. This option is correct because expected results are most effective when they are defined before the testing phase, allowing testers to compare the actual results with the expected results.

Test managers should not:

technology testing

  1. report on deviations from the project plan

  2. sign the system off for release

  3. re-allocate resource to meet original plans

  4. raise incidents on faults that they have found

Show answer
Correct Option: C

Unreachable code would best be found using:

technology testing

  1. a dynamic analysis tool

  2. a debugging tool

  3. a test management tool

  4. a configuration management tool

Show answer
Correct Option: D

What information need not be included in a test incident report:

technology testing

  1. how to fix the fault

  2. how to reproduce the fault

  3. test environment details

  4. severity, priority

Show answer

  1. s = 4, t = 3, u = 2 and 5, v = 1

  2. s = 4 and 5, t = 3, u = 2, v = 1

  3. s = 1 and 5, t = 3, u = 2, v = 4

  4. s = 5, t = 4, u = 3, v = 1 and 2

Which of the following is NOT part of system testing:

technology testing

  1. performance, load and stress testing

  2. requirements-based testing

  3. usability testing

  4. top-down integration testing

What statement about expected outcomes is FALSE:

technology testing

  1. expected outcomes are defined by the software’s behaviour

  2. expected outcomes are derived from a specification, not from the code

  3. expected outcomes include outputs to a screen and changes to files and

  4. expected outcomes should be predicted before a test is run

Show answer
Correct Option: A

The standard that gives definitions of testing terms is:

technology testing

  1. ISO/IEC 12207

  2. BS7925-1

  3. BS7925-2

  4. ANSI/IEEE 829

Show answer
Correct Option: B

The cost of fixing a fault:

technology testing

  1. Is not important
