عدالتی خلع اورپاکستانی عدالتوں کے فیصلوں کی روشنی میں اس کی قانونی بنیادیں Judicial Khul’ and its Legal Grounds in the light of Decisions of Pakistani Courts

The doctrine of Khul’ has, within the course of last few years, assumed a great deal of importance in Pakistan because literacy rate in women is increasing rapidly and their dependency on men is decreasing. Now, women can easily make their own decisions with free consent due to their some awareness about their rights, especially regarding dissolution of marriage. Majority of women is still ignorant about dissolution of marriage on the ground of Khul’. Therefore, it is very necessary to explain all different aspects of “doctrine of Khul’” for ensuring justice in our society. The present research has mainly explored the grounds of judicial Khul’ and other relevant incidents in the light of Pakistani Case Law based on Islamic family Law. The research is based primarily on the decisions of superior courts of Pakistan. The decisions of family courts of Pakistan have been included in the discussion. The relevant provisions of the Dissolution of Muslim Marriages Act, 1939 and the Family Courts Act, 1964 have also been debated. The difference between Khul’ and other modes of dissolution of marriage have also been elaborated briefly.

Automated Testing of Object Oriented Systems Using Vdm++ and Uml Communication Diagrams

The rapidly growing applications of software in critical systems such as railways, aviation, automobiles, and medicine, demand a much higher level of reliability and error- free operation. The use of formal methods in such applications not only helps avoid specification errors, ambiguities, and inconsistencies in early phases of software life cycle, but also provides a sound basis for generation of an effective set of test cases. However, the existing research on formal specification based testing has focused on unit level testing only. This research is aimed at automating the generation of class level as well as integration level test cases for an object-oriented system using formal specifications. We use VDM++ formal specification language for this purpose. As a result of our research, we present a framework, called SpecTGS, that automatically generates specification based test cases for object-oriented systems using VDM++ as the specification language. For class testing, the SpecTGS uses the trace structure definition of a VDM++ class specification to derive allowable method call sequences, and partition analysis to generate test data. For integration testing, we have proposed a novel idea that extracts testing information from the VDM++ specification and UML communication diagrams. The SpecTGS derives message sequences from a UML communication diagram, and uses the VDM++ specification to construct state invariants for the states in which a class can receive a message. A new strategy for constructing sub-states from a state invariant called partitioned boundary state coverage that combines two existing strategies, i.e. partition ivanalysis strategy and the boundary state coverage strategy. Each message sequence generated from the UML communication diagrams is combined with the sub-states to construct a test model. The test model is then used to derive the test paths under various coverage criteria. A proof-of-concept tool has been developed to implement and evaluate the SpecTGS framework. The results for the integration testing approach have been shown for a real-life case study selected from the literature.
