![]() In babies with hypoplastic left heart syndrome, the left side of the heart cannot pump oxygen-rich blood to the body properly. ![]() Normally, these openings will close a few days after birth. When a baby is growing in a mother’s womb during pregnancy, there are two small openings between the left and right sides of the heart: the patent ductus arteriosus and the patent foramen ovale. The left side of the heart pumps oxygen-rich blood to the rest of the body. In a baby without a congenital heart defect, the right side of the heart pumps oxygen-poor blood from the heart to the lungs. Often, babies with hypoplastic left heart syndrome also have an atrial septal defect, which is a hole between the left and right upper chambers (atria) of the heart.The ascending portion of the aorta is underdeveloped or is too small.The aortic valve is not formed or is very small.The mitral valves is not formed or is very small.The left ventricle is underdeveloped and too small.Hypoplastic left heart syndrome affects a number of structures on the left side of the heart that do not fully develop, for example: Because a baby with this defect needs surgery or other procedures soon after birth, HLHS is considered a critical congenital heart defect (CCHD). Hypoplastic left heart syndrome is one type of congenital heart defect. As the baby develops during pregnancy, the left side of the heart does not form correctly. Hypoplastic left heart syndrome (HLHS) is a birth defect that affects normal blood flow through the heart. Closure: Ideally the test manager should close the defect after all the relevant issues have been resolved.Hypoplastic (pronounced hi-puh-PLAS-tik) left heart syndrome or HLHS is a birth defect that affects normal blood flow through the heart.Recurrence: How shall a recurring defect be tracked is or handled should be analysed, whether the defect needs to be marked as a new defect or the previous defect be reopened.Defect Entry: If it occurs to the tester that an unexpected system behaviour has occurred which turns out to be a defect, it should be entered into the defect tracking tool by the tester.A tester is expected to apply diagnostic observation to be able to uncover the test scenarios, from both a positive as well as negative approach. ![]() Analysis: In analysing an application, a tester needs to be a keen observer and should also possess a great deal of knowledge in this regard.Precisely these can be described as the steps or process of defect tracking. ![]() The following points describe the ways to carry out defect tracking. The fixed defect status report must include the description of the fixed as well as other affected areas of the system. The testers record such proceedings into the defect tracking tool. Defects must therefore be prioritized so that high priority defects are dealt with first gradually moving on to the lower priority defects.Įventually as the team keeps solving the issues/defects, the solutions are integrated into a new software build, which instigates retesting. A proper defect tracking system shall aid the developers in their defect correction activities. When the software testing life cycle is planned, the details regarding uncovered defects must be clearly documented by the test team. The implications of defects hidden within the system may prove to be a peril, if not handled with the right acumen. Each phase can be backtracked to a previous one in order to map the defect to its appropriate root cause.ĭefect tracking mechanism is a very crucial aspect of a software development process which must be dealt with great deal of accuracy. A defect may be captured during design, development or testing phase. Defect tracking spans across various levels of software testing. ![]()
