Running Head: Metamorphic Relastion For Effective Testing

Software testing involves execution of a software or service to check the quality of software product or service. It evaluates whether software components meet the given requirements or not. It also evaluates functionality of the software and time taken by it to run. [1] Software testing is very important for controlling the cost of the software project. Traditionally, we design and develop the program first. However, Test Driven Design (TDD) involves writing the test cases for new functions of a software first and then implementation of the code to pass these tests. This cycle of writing test cases and implementing the code is repeated till all the functionalities of the code are implemented. [2] Now, we

The Verification and Validation, or V-model, Software Development Paradigm will be used to define the development life cycle of the software product. This paradigm was chosen because it allows us to test the software during each stage of the project in an inverse way. Also, because the validation and verification of

Test Plan: The software is tested using two levels of testing viz. black box testing and white box testing. White box testing could be carried out in three different phases viz. unit testing system/integration testing and validation testing. • Unit Testing: Unit testing, also known as Module Testing, focuses verification efforts on the module. The module is tested separately and this is carried out at the programming stage itself.Unit Test comprises of the set of tests performed by an individual programmer before integration of the unit into the system. Unit test focuses on the smallest unit of software design- the software component or module. Using component level design, important control paths are tested to uncover errors within the boundary of the module. Unit test is white box oriented and the step can be conducted in parallel for

Purpose: Programmers continually write tests to go along with their code. The tests reflect the stories. Whether you write program before or after you code, write them. Add them to your test suite and make sure to run them every time code changes.

Test-driven design: Developers identify the testing required before beginning to write the code for the system.

Unit testing is a software development process where the smallest testable parts of an application are independently tested in isolation for proper operation. It is often automated and can be done manually. This form of testing is a component of Extreme Programming, where it takes a meticulous approach towards software development by means of continual and revision testing. The unit tests should be calls to these routines with different input parameters. In addition, unit testing involves only the characteristics that are vital to unit performance under test, which encourages the developers to manipulate the source code without immediate concerns about how such changes would affect the functioning of the program as a whole. Once all units in a program has been found to be working efficiently, larger components of the program can be evaluated via integration testing.

Abstract—Although Concolic testing is increasingly being explored as a viable software verification technique, its adoption in mainstream software development and testing in the industry is not yet extensive. In this paper, we discuss challenges to widespread adoption of Concolic testing in an industrial setting and highlight further opportunities where Concolic testing can find renewed applicability.

Software Vulnerability is an unintended flaw in software code or system that leaves it open to the potential for exploitation in the form of unauthorized access or malicious behavior such as viruses, worm and other forms of malware [12]. In order to avoid vulnerabilities in a software, security testing has been implemented, which helps in detecting software vulnerabilities effectively. Some of the methods which help in security testing are black box testing and white box testing [12].

Also Known as functional testing or specification based testing is a method of evaluate the system functionality by ignoring internal mechanism, by a set of valid and invalid data input and code execution conditions the tester tests the systems output response and this method

This research report discusses about the object oriented (OO) environment and the strategies that are used for testing an object oriented environment. The report also lists the tactics and metrics for testing in an object oriented environment. The object oriented approach closely relates the programs to the real world with the help of objects. The popularity of OO approach has increased due to ease of reuse and modular architecture that leads to quality software. Software testing is important to ensure delivery of error free software. Testing an OO program is challenging because of the complexity due to interconnection among the components. Various testing strategies and methods can be followed to test OO software. Apart from the strategies and methods certain metrics need to be considered and used to measure the quality of the projects. Software metrics are proven measures for measuring the development of the software process.

The experience deepens my understanding of software testing as an indispensible element in software development, strengthens my knowledge about software testing and improves my skills of writing effective unit test. Software testing is a widely practiced method for verifying and validating developed software, which is unlikely to fade away in spite of advances in automatic testing and verification. I will reason in this report why testing constitutes an important phase in software development, and try to provide some insights in performing effective testing. Unit testing, among others, is a fundamental approach for software

Though there are many languages currently used for verification, a unique aspect of system Verilog is its support for object-oriented programming. This feature makes it usable in a complex environment for testing higher order systems. Being a language that supports object-oriented programming (OOP), the concept of inheritance can be used that increases the code re-usability and provides better control over the objects used in the environment. Even though the language supports inheritance, there is a lack of support for multiple inheritances and [#inheritance_solution] provides a novel way to overcome this problem.

The testing stage is a basic bit of programming progression .It is the path toward finding process and missing operations moreover a whole affirmation to make sense of if the objectives are met and the customer need are satisfied.

Component based system development offer great flexibility and improvements in large software systems development. Developer of system needs not to start from scratch, but by using Commercial-Off-The-Shelf (COTS) component he can integrate the whole system applying the glue code with component interface. Most of the COTS-components are black box in nature because of source code unavailability, which makes the testing process difficult in development leading to greater testing time and higher cost. Using the test case prioritization technique, we can reduce the cost and time of testing. Most of the test case prioritization techniques proposed in previous works applies source code information as prioritization factors because

The testing discipline includes activities that verify correct functioning of infrastructure and application software components.
