Component Based Software development is used for making the software applications quickly and rapidly. In Component Based Development, the software product is build by gathering different components of existing software from different vendors. By using this process cost and time of the software product is reduced. But in testing phase there arises many difficulties for a tester because he has a very limited access to the source code of the reusable component of the product. The component meta-data can be used to attach additional information with the components to facilitate testing. Black box testing is used where code of the component is not available. Usually, a component has a hidden interface and a tester cannot input the values in it unless its interface is not completed. In this paper, the issues in component based testing using metadata approach for black box testing will be discussed when component's interface not available. We present the methodology that how metadata can be used in black box testing. We have also proposed an application (tool) which can be used in automated black box testing of a <.dll> component.

Autonomous agents perform on behalf of the user to achieve defined goals or objectives. They are situated in dynamic environment and are able to operate autonomously to achieve their goals. In a multiagent system, agents cooperate with each other to achieve a common goal. Testing of multiagent systems is a challenging task due to the autonomous and proactive behavior of agents. However, testing is required to build confidence into the working of a multiagent system. Prometheus methodology is a commonly used approach to design multiagents systems. Systematic and thorough testing of each interaction is necessary. This paper proposes a novel approach to testing of multiagent systems based on Prometheus design artifacts. In the proposed approach, different interactions between the agent and actors are considered to test the multiagent system. These interactions include percepts and actions along with messages between the agents which can be modeled in a protocol diagram. The protocol diagram is converted into a protocol graph, on which different coverage criteria are applied to generate test paths that cover interactions between the agents. A prototype tool has been developed to generate test paths from protocol graph according to the specified coverage criterion.

Aspect oriented software development is an emerging paradigm of software development. The notion of this technique is separation of concerns which means to implement each concern in a single object in object oriented programming but still there are concerns which are distributed on different objects and are called crosscutting concerns while another form is Core concerns are the core functionality provided by the system but crosscutting concerns are the concerns like logging, performance etc. Modeling of aspect oriented software is different from the normal modeling of object-oriented or procedural language software, because aspects don’t have the independent identity or existence and they are tightly coupled to their woven context so it is difficult to model them. The one aim of our research paper is to explore the domain of Modeling of the aspect-oriented software. The goal of this research paper is to give a UML Behavioral modeling techniques in the domain of aspect oriented software development. This technique of generating UML Behavioral Model for aspects will give better understating of separations concerns.

Worldwide Health care services are provided and regulated as well as monitored by applying standard regimens. It is pivotal for patient health, safety and efficient treatment and health services provision. Objective: To assess the knowledge, attitude and Practices of healthcare service providers about Minimum Service Delivery Standards. Methods: It is a cross sectional study in which questionnaire was developed to study minimum service delivery provision towards patients by professional health care providers. A complete Performa was filled by interviewing doctors (MBBS), dentists, nurses, dispensers and para medical staff working at BHUs and RHCs. The data was collected after informed consent following ethical considerations and guidelines by University of Lahore. The data was entered and analyzed using SPSS version 22. Results: The results show the good knowledge of HCPs was resounded in lowest parameter of 1.5% while poor knowledge was scored 95.5%. The attitude of HCPs toward was recorded the positive attitude 58.3% neutral 40.2% while negative attitude 1.5%. the Practices of MSDS at health facility was scored good Practices 4.9% Satisfactory Practices was recorded 0.4% while poor Practices of MSDS was recorded 94.7%. Conclusion: Using MSDS parameter the one can create a better environment of health care to patients. The medical and para medical staff should meet all standards assured in the current study to make a better place for the sake of health and treatment.
