Testing can demonstrate that there are defects in the software, by finding and reporting them. Testing cannot demonstrate that there are no defects, because it is impossible to test all possible scenarios and inputs. Testing cannot demonstrate that the software is correct, because correctness is a subjective and relative concept that depends on the expectations and requirements of the stakeholders. Testing cannot demonstrate that there are no hidden defects in the software, because hidden defects are those that are not detected by testing or other quality assurance activities.

The fundamental test process is a generic model that describes the main activities and tasks involved in testing. The fundamental test process consists of five phases: planning and control, analysis and design, implementation and execution, evaluation of exit criteria and reporting, and test closure activities. Implementation and execution is the phase where test cases and test procedures are implemented according to test specifications and executed on the system or component under test using test tools or manual methods. Implementation and execution also involves verifying that the test environment set up is correct, which means ensuring that the test environment (such as hardware, software, network, data, etc.) is ready and suitable for testing the system or component under test. A detailed explanation of implementation and execution can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 19-21.

 S2 and O2 are the finishing state and the output(s) from the test case1. The question asks about a test case that starts at S1 and triggers 4 events in sequence: E1, E4, E5, E7. The question refers to a state diagram that shows the logic of a system with six states (S1, S2, S3, S4, S5, S6) and seven events (E1, E2, E3, E4, E5, E6, E7). The state diagram also shows four outputs (O1, O2, O3, O4) that are produced by some events. The state diagram is shown below:

!state diagram

To answer this question, we need to follow the path of the test case on the state diagram and observe the state transitions and outputs that occur. The path of the test case is:

• Start at S1
• Trigger E1
• Transition to S2
• Trigger E4
• Transition to S3
• Trigger E5
• Transition to S2
• Output O2
• Trigger E7
• Transition to S6

Therefore, the finishing state of the test case is S2 and the output(s) from the test case is O2. Hence, D is the correct answer.

A testing design technique based in the system requirements. Decision table testing is a black-box testing technique that is used to test complex business rules or logic that involve multiple conditions and actions. Decision table testing uses a tabular format to represent all possible combinations of inputs (conditions) and outputs (actions) for a given decision. Decision table testing helps to ensure that all scenarios are covered and tested. A detailed explanation of decision table testing can be found in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, pages 47-511.

Performance, Load, Stress. Performance testing is a type of non-functional testing that measures how well the system performs under various conditions, such as response time, throughput, resource utilization, etc. Load testing is a type of performance testing that simulates a high volume of user requests or transactions on the system and measures its behavior under normal and peak load conditions. Stress testing is a type of performance testing that simulates extreme or abnormal conditions on the system and measures its behavior under stress or overload conditions. These test types would help verify the requirements such as minimum number of enquiries per hour, availability, and response time under peak loads. A detailed explanation of performance, load, and stress testing can be found in Software Testing Foundations: A Study Guide for the Certified Tester Exam, pages 187-1913.

Testing is the process of evaluating a software product by learning about it through exploration and experimentation, which includes running tests, observing outcomes, making inferences, and creating and refining test ideas. Testing has many objectives, such as finding defects, providing information, improving quality, reducing risks, etc. One of the objectives of testing is preventing defects, which means avoiding or minimizing the occurrence of defects in the software product by applying good practices and techniques throughout the software development life cycle. Preventing defects can help to save time, cost, and effort in testing and development, and improve customer satisfaction and confidence. A detailed explanation of testing objectives can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 7-8.

Metrics are quantitative measures that can be used to monitor and control various aspects of software testing processes and products1. Metrics can be used to monitor progress along with test preparation and execution by providing information about the status of testing activities, such as test planning, test design, test execution, test evaluation, defect management, etc1. Among the options given in this question, only C is a suitable metric for monitoring progress along with test preparation and execution. The failure rate in testing already completed is a metric that measures how many tests have failed out of the total number of tests executed1. This metric can indicate the quality of the software product under test and the effectiveness of the test cases1. It can also help to identify areas that need more attention or improvement in testing1. Therefore, this metric can be used to monitor progress along with test preparation and execution.

The main reason for using a pilot project to introduce a testing tool into an organization is C. To assess whether the tool will be cost-effective. A pilot project is a small-scale trial or experiment that is used to evaluate the feasibility, benefits, risks, and challenges of introducing a testing tool into an organization. A pilot project can help to assess whether the tool will be cost-effective, by comparing the costs of acquiring, deploying, using, and maintaining the tool with the benefits of using the tool, such as increased efficiency, effectiveness, quality, etc. A pilot project can also help to identify any technical, organizational, or human factors that may affect the successful adoption of the tool, and plan for any necessary actions or changes to address them. A detailed explanation of pilot projects can be found in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, pages 115-1161.

A consideration when deploying test execution tools is B. Recorded manual tests may become unstable in use. Test execution tools can record manual tests performed by a tester and replay them automatically on demand. However, recorded manual tests may become unstable or unreliable in use, due to various factors, such as changes in the system under test, changes in the test environment, changes in the user interface, timing issues, synchronization issues, etc. Therefore, recorded manual tests may require frequent maintenance or modification to keep them up to date and consistent with the system under test. A detailed explanation of recorded manual tests can be found in A Study Guide to the ISTQB® Foundation Level 2018 Syllabus, pages 112-113

 These are some of the factors that should be considered to determine whether enough testing has been performed. The exit criteria define the specific goals and requirements for testing completion. The budget limits the resources and time available for testing. The product’s risk profile indicates the areas of highest priority and impact for testing. Sufficient details of the system status allow decisions on whether further testing is needed or not. The other options are not relevant factors for determining enough testing.
