A test condition is an item or event of a component or system that can be verified by one or more test cases. A test condition can be derived from various sources of information, such as requirements, specifications, design documents, use cases, user stories, etc. A test condition can also be based on various aspects of a component or system, such as functionality, usability, performance, reliability, security, etc.

The other statements are not true about test conditions because they describe different concepts related to testing. For example:

B. The grouping of a composite set of test cases which, when tested as a whole, reveal a positive or negative result: This statement describes a test suite, which is a collection of test cases that are intended to be executed together to achieve a specific test objective or goal.

C. A testable component derived from business requirements: This statement describes a test basis, which is the source of information or data that provides the basis for designing and executing test cases.

D. Applies to software testing only: This statement is false because test conditions can apply to any type of testing, not just software testing. Test conditions can also be used for testing hardware, systems, processes, etc.

You can find more information about test conditions in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.1.

 Integration testing is a test level that accurately defines the integration testing test level1. Integration testing is a type of testing that verifies that different components or systems work together correctly and consistently1. The test basis for integration testing includes software and system design documents that specify how the components or systems are integrated and interact with each other1. The test objects for integration testing include interfaces between components or systems that enable data exchange or communication1. The tests for integration testing concentrate on the interactions between different parts of a system and check for functional, performance, reliability, security, compatibility, and interoperability issues1. Therefore, integration testing is a test level that accurately defines the integration testing test level.

The Cambrian Pullman Express has special ticketing requirements represented by the partial decision table below. The decision table has six columns representing six rules and eight rows representing eight conditions or actions. The table is filled with “Y” and “N” values indicating whether a particular condition is met for a particular rule.

Carol has a student railcard and is travelling on a Flexible Standard Class ticket. James has a senior railcard and is travelling on a super saver ticket. The question asks which of the options represents the correct actions for these two test cases. To answer this question, we need to find the matching rule for each test case and then look at the corresponding actions. For Carol, the matching rule is rule 2, as she has a student railcard (Y) and a Flexible Standard Class ticket (Y). The actions for rule 2 are: OK to travel (Y), eligible to upgrade (Y), and concessionary fare (N). Therefore, Carol is OK to travel and eligible to upgrade, but not entitled to a concessionary fare. For James, the matching rule is rule 6, as he has a senior railcard (Y) and a super saver ticket (N). The actions for rule 6 are: OK to travel (N), eligible to upgrade (N), and concessionary fare (N). Therefore, James cannot use the service, is not eligible to upgrade, and is not entitled to a concessionary fare. Among the options given in this question, only A correctly represents these actions. A says that Carol is eligible to upgrade and James cannot use the service. Therefore, A is the correct answer.

Testers should be involved in reviewing a UAT specification as soon as the UAT specification has been drafted1. UAT stands for user acceptance testing, which is a type of testing that verifies that the software product meets the acceptance criteria and expectations of the end users or customers1. A UAT specification is a document that defines the scope, objectives, approach, and criteria for UAT1. Testers should be involved in reviewing a UAT specification as soon as the UAT specification has been drafted, as this can help to ensure that the UAT specification is clear, complete, consistent, testable, and aligned with the user requirements1. Testers can also provide feedback and suggestions to improve the UAT specification and avoid potential issues or conflicts during UAT execution1. Therefore, testers should be involved in reviewing a UAT specification as soon as the UAT specification has been drafted.

Static code analysis is a technique that examines the source code or other software artifacts without executing them, and can detect defects, vulnerabilities, code smells, and deviations from standards early in the development process1. According to the ISTQB syllabus, one of the benefits of static testing is early defect detection2, which can reduce the cost and effort of fixing them later.

Statement coverage is not a black box technique, because it requires knowledge of the internal structure of the code. Black box techniques are based on the external behavior and specification of the software, without looking at the code. Equivalence partitioning, state transition testing, and boundary value analysis are all examples of black box techniques12

It can be done without reference to the internal structure of the component or system. Black-box testing techniques are based on the external behavior and functionality of the system, not on its internal structure or code. Black-box testing techniques include equivalence partitioning, boundary value analysis, decision table testing, state transition testing, use case testing, etc. A detailed explanation of black-box testing techniques can be found in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, pages 25-601.

Defect clustering is the phenomenon that a small number of modules contain most of the defects detected. This principle suggests that testing should focus more on the areas where defects are more likely to occur, rather than spreading the testing effort equally across all modules. Therefore, in the next test cycle, the team should allocate more resources to test the module that had most of the critical bugs.

According to the syllabus, decision tables are a technique that shows combinations of inputs and/or stimuli (causes) with their associated outputs and/or actions (effects). The answer B is correct because it matches the rules in the decision table for the given test case. The other answers are incorrect because they do not match the rules in the decision table for the given test case.

Experience-based testing is the test design technique for which a document containing a classification of all the defects found during the system test phase and after the delivery in the production environment can be considered a test basis. Experience-based testing is a technique that relies on the knowledge and intuition of the testers to design and execute test cases based on their experience with similar systems, technologies, domains, or defects. A document containing a classification of all the defects found during the system test phase and after the delivery in the production environment can provide valuable information and insights for testers to identify potential defect-prone areas or scenarios and focus their testing efforts accordingly1 explains experience-based testing as follows:

Experience-based testing techniques are based on the tester’s experience, knowledge and intuition. These techniques leverage the tester’s skill in finding defects and designing tests that are effective in exposing failures. Experience-based testing techniques are often used when there is no or insufficient documentation available for the system under test, or when there is not enough time to apply more formal techniques.

Some examples of experience-based testing techniques are:

Error guessing: The tester uses their personal experience or intuition to guess what functionality might fail or cause errors, and designs test cases accordingly.

Exploratory testing: The tester simultaneously learns about the system, designs test cases, executes tests, and reports results, using an iterative and interactive approach.

Checklist-based testing: The tester uses a list of items or tasks that need to be verified or completed during testing, based on previous experience or best practices.

A, C, and D are incorrect answers. Structure-based testing, decision coverage testing, and specification-based testing are not test design techniques for which a document containing a classification of all the defects found during the system test phase and after the delivery in the production environment can be considered a test basis. Structure-based testing is a technique that uses the information of the internal structure of the component or system to derive test cases. Decision coverage testing is a type of structure-based testing that aims to cover all the possible outcomes of each decision in the code (true and false) at least once. Specification-based testing is a technique that uses the requirements and functionality of the system to derive test cases. These techniques require access to the source code or documentation of the system under test, which are not provided by a document containing a classification of all the defects found during the system test phase and after the delivery in the production environment.
