Which of the following metrics would be MOST useful to monitor during test execution?

• Percentage of executed test cases
• Average number of testers involved in the test execution
• Coverage of requirements by source code
• Percentage of test cases already created and reviewed

Consider a mobile app that allows customers to access and manage their bank accounts. A user story has just been added to the set of features that checks customers’ social media accounts and bank records to give personalized greetings on birthdays and other personal milestones. Which of the following test techniques could a PROGRAMMER use during a unit test of the code to ensure that coverage of situations when the greetings ARE supposed to occur and when the greetings ARE NOT supposed to occur?

• Statement testing
• Exploratory testing
• State transition testing
• Decision testing

Which of the following options are roles in a formal review?

• Developer, Moderator, Review leader, Reviewer, Tester
• Author, Moderator, Manager, Reviewer, Developer
• Author, Manager, Review leader, Reviewer, Designer
• Author, Moderator, Review leader, Reviewer, Scribe

Which of the following statements comparing component testing and system testing is TRUE?

• Component testing verifies the functionality of software modules, program objects, and classes that are separately testable, whereas system testing verifies interfaces between components and interactions between different parts of the system
• Test cases for component testing are usually derived from component specifications, design specifications, or data models, whereas test cases for system testing are usually derived from requirement specifications or use cases
• Component testing only focuses on functional characteristics, whereas system testing focuses on functional and non-functional characteristics
• Component testing is the responsibility of the testers, whereas system testing typically is the responsibility of the users of the system

Which of the following provides the BEST description of exploratory testing?

• A testing practice in which an in-depth investigation of the background of the test object is used to identify potential weaknesses that are examined by test cases
• An approach to testing whereby the testers dynamically design and execute tests based on their knowledge, exploration of the test item and the results of previous tests
• An approach to test design in which test activities are planned as uninterrupted sessions of test analysis and design, often used in conjunction with checklist-based testing
• Testing based on the tester's experience, knowledge, and intuition

Which of the following statements correctly describes the difference between testing and debugging?

• Testing identifies the source of defects; debugging analyzes the defects and proposes prevention activities
• Dynamic testing shows failures caused by defects; debugging eliminates the defects, which are the source of failures
• Testing removes faults; but debugging removes defects that cause the faults
• Dynamic testing prevents the causes of failures; debugging removes the failures

Which of the following statements CORRECTLY reflects the value of static testing?

• By introducing reviews, we have found that both the quality of specifications and the time required for development and testing have increased
• Using static testing means we have better control and cheaper defect management due to the ease of detecting defects later in the lifecycle
• Now that we require the use of static analysis, missed requirements have decreased and communication between testers and developers has improved
• Since we started using static analysis, we find coding defects that might have not been found by performing only dynamic testing

You are testing a mobile app that allows customers to access and manage their bank accounts. You are running a test suite that involves evaluating each screen and each field on each screen against a general list of user interface best practices, derived from a popular book on the topic, that maximize attractiveness, ease-of-use, and accessibility for such apps. Which of the following options BEST categorizes the test technique you are using?

• Specification-based
• Exploratory
• Checklist-based
• Error guessing

Which of the following statements CORRECTLY describes a role of impact analysis in Maintenance Testing?

• Impact analysis is used when deciding if a fix to a maintained system is worthwhile
• Impact analysis is used to identify how data should be migrated into the maintained system
• Impact analysis is used to decide which hot fixes are of most value to the user
• Impact analysis is used to determine the effectiveness of new maintenance test cases

A mass market operating system software product is designed to run on any PC hardware with an x86-family processor. You are running a set of tests to look for defects related to support of the various PCs that use such a processor and to build confidence that important PC brands will work. What type of test are you performing?

• Performance test
• Processor test
• Functional test
• Portability test
