A potential infinite loop is a type of defect that can be typically identified using static analysis by tools1. Static 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. Static analysis tools are software tools that automate the static analysis technique and provide various features and functionalities to support it1. Static analysis tools can identify a potential infinite loop by analyzing the control flow and data flow of the source code and checking for conditions or statements that may cause an endless repetition or iteration1. A potential infinite loop can cause serious problems in software performance, functionality, reliability, and security1. Therefore, a potential infinite loop is a type of defect that can be typically identified using static analysis by tools.

 Test objectives are specific goals or targets that define what testing activities should achieve or accomplish1. Test objectives for systems testing of a safety critical system include completion of all outstanding defect correction. Regression testing is required following defect correction at all test levels. Therefore, to determine whether this test objective has been met, two metrics that would be most suitable are:

• Regression tests run and passed in systems testing: This metric measures how many regression tests have been executed and passed in systems testing1. Regression testing is a type of testing that verifies that previously tested software still performs correctly after changes or defect corrections1. This metric can indicate whether all outstanding defect corrections have been completed and verified in systems testing.
• Incidents raised and closed at all levels of testing: This metric measures how many incidents have been reported and resolved at all levels of testing1. An incident is any event occurring during testing that requires investigation1. This metric can indicate whether all defects have been identified and corrected at all levels of testing.

It is not allowed as organizations can’t change the test levels as these are chosen on the basis of the SDLC (software development life cycle) model. The V-model is a type of SDLC model that defines four test levels: component testing, integration testing, system testing, and acceptance testing. Each test level corresponds to a development phase in a parallel manner. Integration testing is an essential part of the V-model, as it verifies that the components work together correctly and consistently2 explains this as follows:

The V-model is a graphical representation of a systems development lifecycle. It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model and the US government standard.

The V-model summarizes the main steps to be taken in conjunction with the corresponding deliverables within project execution and delivery. It describes software development activities from requirements specification to maintenance.

The V-Model demonstrates the relationships between each phase of the development life cycle and its associated phase of testing.

A, C, and D are incorrect answers. A implies that integration testing is not an important test level and can be dispensed with, which is not true as integration testing ensures that the system functions as a whole and meets its requirements. C implies that organizations can decide on which test levels to do depending on the context of the system under test, which is not true as test levels are determined by the chosen SDLC model and its objectives. D implies that integration testing is a very important test level and ignoring it means definite poor product quality, which is true but not relevant to why it is not allowed to do away with integration testing in a V-model.
