Software testing plays an important role in the achievement of software quality and reliability. Testing process can start at initial phase of development and continue till the deployment phase. Testing the software module by module reduces the number of bugs released during the deployment. Unit testing is used to determine whether the source code is fit for use. The major goal of unit testing is to separate each part of the program and test that the individual modules are working correctly. It isolates the modules of testable software from the entire code and finds whether it behaves exactly as your expectation. It is proven that a large percentage of defects are identified during unit testing. It supports automation and reduces the difficulty of discovering errors contained in more complex parts of the application. It gives attention to each unit of the code. In unit testing, JUnit framework with GUI techniques plays a significant role in development of real time software. Since the bugs are found early, Junit testing helps reduce the cost of bug fixes. Because the cost of debugging at the deployment phase is higher than the cost at module building phase. It deals with multiple test cases so that various boundary conditions are checked for each module.

IoT is an emerging technology in recent times. Fog computing is a part of Internet of Things. Fog computing has good business agility, high security, deeper privacy control, lesser operating expenses. Scheduling of task is an importance function in multitasking systems where multiple requests are submitted for processing simultaneously. Various scheduling algorithms are available for ordering the requests in cloud type of storage. But tasks are handles differently in fog computing. Fog nodes are the devices involved in fog computing. The fog computing devices can be used anywhere in the open space with a network establishment without any constraints on environment like cloud servers.

Ophthalmic exercise is massage method that aims at promoting students awareness of eye production, improving blood circulation and relaxing muscles in ocular region, reducing the eye strain of students with myopia. The aim of the study to identify the effect of ophthalmic exercise among students with myopia at selected college Coimbatore. Quasi experimental one group pretest and post test research design was adopted in this study. The samples were selected using Non probability purposive sampling technique. Among 35 samples, 23 samples were Iyear, four samples were IIyear and eight samples were III year. The level of knowledge among students with myopia was assessed using self structured questionnaire before and after ophthalmic exercise. Ophthalmic exercise were demonstrated by using flashcard and slide projector and students continued to practice the exercises for 15 minutes twice a day for one week. The duration of exercise was 20 minutes. The level of eye strain was assessed by using asthenopic symptoms scale before and after intervention. It was identified that the mean level of knowledge among students with myopia during pre test and post test was 13.6 and 16.08 respectively with the standard deviation of pre test and post test was 0.64 and 1.59 respectively. The calculated ‘t ’ value 10.75 was greater than the table value 1.96 at 0.05 level of significance. It was identified that the mean level of eye strain among students during pretest and post test was 4.08 and 2 respectively with a standard deviation of pre test and post test was 2.01 and 1.19 respectively. The calculated ‘t’ value 5.94 was greater than the table value 1.96 at 0.001 Level of significance. Hence it was concluded that ophthalmic exercises is an effective intervention in reducing the level of eye strain among students with myopia.Keywords
