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

An item or event that could be verified by one or more test cases. A test condition is a general term that refers to anything that can be tested by a test case, such as a requirement, a function, a feature, a use case, a user story, etc. A test condition is derived from the test basis (the source of information for testing) and serves as an input for test design and test case creation. A test condition can be expressed in natural language or in a formal notation. A detailed explanation of test condition can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 17-18.

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.

Multiple condition coverage is a structure-based test technique that aims to achieve a high level of coverage by testing all possible combinations of conditions and outcomes in each decision point of the code or design of the system under test. Multiple condition coverage verifies that each condition in a decision point has an effect on the outcome and that there are no hidden defects or logical errors in the code or design. Multiple condition coverage requires some knowledge of the internal structure or implementation of the system under test; it focuses on how the system does what it does rather than what it does. Multiple condition coverage is one of the most rigorous and complex structure-based test techniques because it can generate a large number of test cases for each decision point, especially if there are many conditions involved. You can find more information about multiple condition coverage in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.3.
