CTFL_Syll2018 Exam Dumps : ISTQB Certified Tester Foundation Level (Syllabus 2018)

The statement that use case testing is designed to find defects in the process flow is true, because use case testing is a technique that tests the end-to-end user interactions and outcomes based on use cases or scenarios that describe how the software under test should be used . Use case testing can help to find defects in the process flow, such as missing steps, incorrect sequences, or invalid transitions . The other options are not true statements about use case testing. Option A is false, because use case testing is not designed to be used by real users, but rather by professional testers who design and execute test cases based on use cases or scenarios . Option C is false, because use case testing is not designed to find defects in the data flow, but rather in the process flow. Data flow testing is a different technique that tests how data values are defined, used, and modified by the software under test . Option D is false, because use case testing is not always designed by customers or end users, but rather by testers who analyse the requirements or specifications of the software under test to identify use cases or scenarios .

The Test Analysis and Design activity of the test process is the activity where test conditions and test cases are identified and specified based on the test objectives and criteria. The Test Analysis and Design activity also involves identifying and preparing the necessary test data and test environment to support the test execution. Some of the tasks of the Test Analysis and Design activity are:

• Reviewing the test basis: This task involves reviewing the requirements, specifications, design documents, or other sources of information that form the basis for testing.
• Identifying test conditions: This task involves identifying what needs to be tested based on the test basis and objectives.
• Designing and prioritizing test cases: This task involves designing specific scenarios or steps to verify each test condition and assigning priorities to them based on their importance or risk level.
• Identifying necessary test data to support the test conditions and test cases: This task involves identifying what data is needed to execute each test case and how to obtain or generate it.
• Identifying and preparing the test environment: This task involves identifying what hardware, software, network, data, tools, etc., are needed to execute the test cases and how to set up and maintain them.

Measuring the percentage of prepared test cases with what was actually prepared is not a task of the Test Analysis and Design activity because it does not involve identifying or specifying anything related to testing. Rather, it is a task of the Test Monitoring and Control activity, which involves measuring and reporting the progress and status of testing against the planned activities and criteria. You can find more information about the Test Analysis and Design activity in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 31.

Memory leaks are errors that occur when a program does not release memory that it has allocated, causing the system to run out of memory and slow down or crash. Memory leaks cannot be detected by structure-based testing techniques, which are based on the code structure and logic. Structure-based testing techniques can only find errors that are related to the control flow, data flow, or logic of the program. For example, they can find errors such as features that are only partially implemented, data structures that are used before initialization, or division by zero. To detect memory leaks, you need dynamic analysis tools that monitor the memory usage of the program during execution. You can find more information about structure-based testing techniques and dynamic analysis tools in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, Chapter 4, Sections 4.2 and 4.31.
