1. 1. Which one of the following answers describes a test condition?

• A distinguishing characteristic of a component or system
• A testable aspect of a component or system identified as a basis for testing
• The degree to which a software product provides functions which meet stated and implied needs when the software is used under specified conditions
• Test cases designed to execute combinations of conditions and actions resulting from them

2. 2. Which of the following statements is a valid objective for testing?

• The test should start as late as possible so that development had enough time to create a good product

• To find as many failures as possible so that defects can be identified and corrected

• To prove that all possible defects are identified

• To prove that any remaining defects will not cause any failures

3. 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 does removes faults; but debugging removes defects that cause the faults
• Dynamic testing prevents the causes of failures; debugging removes the failures

4. Which one of the statements below describes the most common situation for a failure discovered during testing or in production?

• The product crashed when the user selected an option in a dialog box

• The wrong version of a compiled source code file was included in the build

• The computation algorithm used the wrong input variables

• The developer misinterpreted the requirement for the algorithm

5. 5. Mr. Test has been testing software applications on mobile devices for a period of 5 years. He has a wealth of experience in testing mobile applications and achieves better results in a shorter time than others. Over several months Mr. Test did not modify the existing automated test cases and did not create any new test cases. This leads to fewer and fewer defects being found by executing the tests. What principle of testing did Mr. Test not observe?

• Testing depends on the environment

• Exhaustive testing is not possible

• Repeating of same tests will not find new defects

• Defects cluster together

6. In what way can testing be part of Quality Assurance?

• It ensures that requirements are detailed enough

• It contributes to the achievement of quality in a variety of ways

• It ensures that standards in the organization are followed

• It measures the quality of software in terms of number of executed test cases

7. Which of the following activities is part of the main activity "test analysis" in the test process?

• Identifying any required infrastructure and tools

• Creating test suites from test scripts

• Analyzing lessons learned for process improvement

• Evaluating the test basis for testability

8. Match the following test work products (1-4) with the right description (A-D).

1. Test suite

2. Test case

3. Test script

4. Test charter

*****

A. A set of test scripts to be executed in a specific test run

B. A set of instructions for the execution of a test

C. Contains expected results

D. Documentation of test activities in session-based exploratory testing

• 1A, 2C, 3B, 4D
• 1D, 2B, 3A, 4C
• 1A, 2C, 3D, 4B
• 1D, 2C, 3B, 4A

9. How can white-box testing be applied during acceptance testing?

• To check if large volumes of data can be transferred between integrated systems

• To check if all code statements and code decision paths have been executed

• To check if all work process flows have been covered

• To cover all web page navigations

10. 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 nonfunctional characteristics

• Component testing is the responsibility of the testers, whereas system testing typically is the responsibility of the users of the system
