Automated Test Case Generation Techniques For Object Oriented Software

Programming testing is the methodology of executing a program or framework with the purpose of finding faults. Testing is a procedure of affirming that item is working as per the requirments, fulfilling the client needs. Programming testing gives a way to decrease errors, cut maintenance and general programming costs. Various programming testing strategies, techniques, and systems have developed in the course of the most recent couple of decades promising to improve programming quality. Programming testing is vital part in the product development life cycle. Two regular methodologies are white box testing and discovery testing. There are diverse scope measure for testability to the source code, for example, statement coverage, branch coverage and condition coverage. In the branch coverage we ensure that we execute each branch in any event once For conditional branches, this implies, we execute the TRUE branch in any event once and the FALSE branch in any event once conditions for conditional branches can be compound boolean expressions a compound boolean

Only a small number of possible inputs can be tested and many program paths will be left untested.

Integration tests are used to test integrated software components that determines they actually run as one program. This testing is more concerned and the event driven with the basic outcome of the fields or screens. Integration tests demonstrate that even the components were individually satisfaction, as shown before by the successful unit testing, the both combination of the component is consistent and correct. Integration testing is mainly used at showing the problem that arise from the combination of components.

Black box testing involves in generation of the test case using strategies like mutation, without considering source code structure. Which are fed to the system later [12]. The

Software engineering is the branch of computer science that helps in developing good software. Good software is that software that can handle all kinds of runtime situations and provide user friendly messages. Software process models strive to help developers to build applications in systematic manner. However, software industry has plethora of illustrations that prove that the developed software has defects. Defect is something that does not comply with the functional requirement of the system. Finding fixing defects in the software system is to be given paramount importance it helps in improving quality of the software under test.

Only a small number of possible inputs can be tested and many program paths will be left untested.

Testing is an important process in software development and widely used by developers to reveal bugs. Often, software failures can lead to disastrous consequences such as loss of data, fortune and lives. Test engineers have generated a set of test cases to validate against the user requirements. The highest number of reduction can save a cost of testing. When dealing with a large line of code (LOCs) there still has redundancy happened. Our experiment studies about hybrid tReduct GNA_SA and the existing strategies to counter test redundancy reduction issues. In our experiment, we apply four (tReductLAHC, tReductSA, tReductGNA and tReduct GNA_SA) test-suite reduction strategies for six different situation. After that, we then measure the effectiveness of the diversified solutions of four test suite reduction strategies. Our experiment shows that a new hybrid strategy tReduct GNA_SA offers more effectiveness to reduce redundancy compared to existing work.

Software testing can be defined as the process of accessing the correctness of a software through an analysis of the system. The main purpose can be validation, verification and quality assurance and to affirm the quality of software system by systematically testing the software in controlled environments and to identify whether the software is complete as well as correct. For a software to be considered complete or fit for use it must pass each of the test. The fundamental problem that not all errors in a program are possible to find throws a question as to what method to adopt for testing. This paper discusses and compares the two most prevalent software testing techniques which are white box testing and black box testing. We will discuss the pros and cons of both approaches and which method should be used to deliver a quality software to the market.

The quality of the generated tests permits to verify the absence of critical errors in the use cases. The tool is able to build and execute generated tests and detect the problems of all kinds of emitted signals, non-zero program return code and also program hanging.

This report, entitled “Software Testing and Test Cases”, aims to assess the importance of software testing in developing successful software, and how to write effective and efficient unit test to fulfill testing requirements. As a Front-end Engineer Intern in the Web Development Team, I participated in designing and implementing front-end features to achieve and optimize users’ needs when using Verdigris’ internal utility dashboard. During the development procedure, software testing manifests itself as indispensible in determining the soundness, completeness, security and quality of the developed software. To fulfill testing goals, it is crucial to write effective unit test.

Software testing is an important means of accessing quality of software which is an essential, but time and resource consuming activity in the software development process. Though a lot of advancements have been done in formal methods and verification techniques, still we need software to be fully tested before it could be handled to the customer. Thus there are a number of testing techniques and tools made to accomplish the task. Software testing is an important area of research and a lot of development has been made in this field and gaining more and more importance in the future. Test automation has been done to reduce the cost of testing. Traditionally the test automation has been focused mainly on automating the test management and test execution. Unfortunately, the test design often still remains a manual activity. The test design itself concerns making the decisions on

Class Performance: This work made classes have enough attributes and enabled them to improve performance as a refining object-oriented system by deleting unnecessary relationship of classes on applying various equipment in object-oriented supporting for software system refining.

Testing can be done either manually or automatically. Testing is an important and heavily used technique to measure and ensure software quality. It is part of almost any software project. The testing phase of typical projects take up to 50% of the total project effort, [1] and hence contributes significantly to the project costs. Any change in the software can potentially influence the result of a test. For this reason tests have to be repeated often. This is error-prone, time consuming and expensive. Automatic testing significantly reduces the effort of individual tests. This implies that performing the same test becomes cheaper, or one can do more tests within the same budget. Manual testing is time consuming, unreliable and costly while Automated testing in contrast is reliable and requires less investment in human resources.

Integration testing is a systematic technique for constructing the software architecture while at the same time conducting tests to uncover errors associated with interfacing. The different modules in our project were interfaced and tested in small increments, thus making the errors easy to isolate and correct. This is known as incremental

Combinatorial Interaction Testing (CIT) is a disclosure system in recognizing programming blemishes. CIT is used to test significantly configurable programming structures & GUI event progressions. Combinatorial Interaction Testing (CIT) is Associate in nursing calm and capable strategy for police work disillusionments that square measure realized by the relationship of changed systems illumination parameters. Combinatorial Interaction Testing (CIT) is a compelling and reasonable framework for perceiving accuses or dissatisfactions that are brought for by the associations of distinctive structure data parameters. Earlier work used Feedback Driven Adaptable Combinatorial Interaction Testing method (FDA-CIT) to recognize the accuse that happened in every one examinations. At each attention of FDA-CIT issues are perceived and the recognized imperfections are represented and indicated. However change in accuracy for deficiency correction is not gained. To address this issues this present work proposes issue characterization concentrated around
