To answer this question, you need to understand the concept of fault masking.

Option A) Error condition hiding another error condition - This option is correct because fault masking refers to a situation where one error condition hides or masks another error condition. In other words, the presence of one fault in a system may prevent the detection of another fault.

Option B) Creating a test case which does not reveal a fault - This option is incorrect because fault masking is not related to creating test cases. It is about the presence of one error condition hiding another error condition.

Option C) Masking a fault by a developer - This option is incorrect because fault masking is not done intentionally by a developer. It is a situation that can occur unintentionally in a system when one fault hides another fault.

Option D) Masking a fault by a tester - This option is incorrect because fault masking is not done intentionally by a tester. It is a situation that can occur unintentionally in a system when one fault hides another fault.

The correct answer is A) Error condition hiding another error condition. This option is correct because it accurately describes the concept of fault masking.

To answer this question, you need to understand test coverage criteria. Test coverage criteria refer to the extent to which a test suite or set of tests covers the requirements or components of a system. Let's go through each option to understand why it is correct or incorrect:

Option A) A measure of test coverage criteria is the percentage of user requirements covered. - This option is correct because one of the measures of test coverage criteria is indeed the percentage of user requirements covered. It helps determine how well the test suite covers the specified requirements.

Option B) Test coverage criteria can be measured in terms of items exercised by a test suite. - This option is incorrect because measuring test coverage criteria in terms of items exercised by a test suite is a valid approach. It helps assess the effectiveness of the tests in exercising the different components or functionalities of a system.

Option C) A measure of test coverage criteria is the percentage of faults found. - This option is correct because one of the measures of test coverage criteria is indeed the percentage of faults found. It helps evaluate how well the tests are able to detect faults or defects in the system.

Option D) Test coverage criteria are often used when specifying test completion criteria. - This option is correct because test coverage criteria are commonly used when determining test completion criteria. Test coverage criteria help define the minimum level of coverage that needs to be achieved before considering the testing phase complete.

The correct answer is Option B. This option is not true because test coverage criteria can indeed be measured in terms of items exercised by a test suite.

Therefore, the correct answer is B.

To answer this question, you need to understand the activities involved in the selection and implementation of a testing tool. Let's go through each option to understand why it is correct or incorrect:

Option A) i, ii, iii - This option is incorrect because it includes activity iii, which suggests implementing the selected tool on a project behind schedule to save time. This is not a recommended practice as it can introduce additional risks and potentially worsen the situation.

Option B) ii, iii, iv - This option is incorrect because it does not include activity i, which is to investigate the organization's test process. Understanding the organization's test process is crucial in selecting and implementing a testing tool that aligns with the organization's needs and requirements.

Option C) i, iii, iv - This option is incorrect because it does not include activity ii, which is to conduct a proof of concept. Conducting a proof of concept helps evaluate the tool's capabilities and suitability before making a final decision.

Option D) i, ii, iv - This option is correct because it includes all the recommended activities during the selection and implementation of a testing tool.

The correct answer is D. This option is correct because it includes investigating the organization's test process (i), conducting a proof of concept (ii), and identifying coaching and mentoring requirements (iv), which are all important steps in ensuring the successful selection and implementation of a testing tool.

To answer this question, you need to understand the benefits of using test tools. Let's go through each option to understand why it is correct or incorrect:

Option A) ii and iv - This option is incorrect because it includes only two benefits, but the correct answer has four benefits.

Option B) ii and iii - This option is incorrect because it includes only two benefits, but the correct answer has four benefits.

Option C) i and iv - This option is correct because it includes the benefits of easy access to information about tests and testing (i) and greater consistency of tests (iv), both of which are likely to be achieved by using test tools.

Option D) i and iii - This option is incorrect because it includes the benefit of easy access to information about tests and testing (i), but it does not include the benefit of reduced maintenance of testware (ii), which is also likely to be achieved by using test tools.

The correct answer is C. This option is correct because it includes both the benefits of easy access to information about tests and testing and greater consistency of tests, which are likely to be achieved by using test tools.

To answer this question, you need to understand the different categories of tool support in software testing.

Option A) Tool support for performance and monitoring - This option is incorrect. Tools associated with performance and monitoring typically focus on measuring and analyzing the performance of the software during runtime, rather than comparing the actual results of a test with the expected results.

Option B) Tool support for static testing - This option is incorrect. Static testing tools are used to analyze the source code or documentation of the software without executing it. They do not involve comparing test results.

Option C) Tool support for test execution and logging - This option is correct. A test comparator tool is usually associated with test execution and logging. It is used to compare the actual results of a test with the expected results and log any discrepancies or failures.

Option D) Tool support for the management of testing and tests - This option is incorrect. Tools for the management of testing and tests typically focus on test planning, test case management, and test reporting. They do not specifically deal with comparing test results.

The correct answer is C) Tool support for test execution and logging. This option is correct because test comparator tools are commonly used in the execution phase of testing to compare actual and expected results and log any deviations or failures.
