Regress Analysis & Impact of Requirement Coverage to Minimize Test Suite with Implementation of Incremental Algorithm

Data Mining Techniques can be applied to solve software engineering defects and bugs. Software development team tries to enhance software quality and efficiency by minimizing the defect ratio to the least possible extent. Software life cycle is a human activity dependent

Software testing is the process of evaluating a software item to identify differences between given input and expected output. It also confirms that the feature and functions of the software going to be working according to the specifications and requirements. It is considered as most important part of software development cycle(SDLC). Testing actually defines the quality of the product. Software testing is a process which should be done during the development process and the system is complete.

An inspection or walkthrough is a detailed examination of a product on a step-by-step or line-of-code by line-of-code basis. The purpose of conducting inspections and walkthroughs is to find errors. The group that does an inspection or walkthrough is composed of peers from development, test, and quality assurance. 2. Testing Testing is the operation of the software with real or simulated inputs to demonstrate that a product satisfies its requirements and, if it does not, to identify the specific differences between expected and actual results.

This will enable the user to realize the problems faced by software testers and the importance of software testing. Software testing is the “process of executing a software system to determine whether it matches its specification and executes in its intended environment” (Whittaker 71). It is often associated with locating bugs, program defects, faults in the source code, which cause failures during execution that need to be removed from the program. Locating and removing these defects is called debugging, which is different from the testing that establishes the existence of these defects. Specifications are crucial to testing because they identify correct behavior so that software failures corresponding to incorrect behavior can be identified.

Whenever modifications are done in this phase retesting of software application is required. The process of retesting such a software is called regression testing. Regression testing is a type of software testing that seeks to check that the changes made to a system have not introduced new faults in the system. Though regression testing is expensive, it is necessary to perform it on the modified software. A consistent, repeatable validation of each changes made in the applications, are provided by the regression testing.

Test case design is done a set of techniques for the creation of cases that meet overall testing objectives. Testing Objectives Are • Testing is a process of executing of a program with intend of finding an error. • A good test case is one which is having a high probability of finding an error as yet uncovered error. • A successful test is one that uncovers and yet undiscovered error. Our objectives is to design that systematically uncover different classes of errors and performing the same with minimum amount of time and effort.

In order to overcome these issues and deficiencies, project managers must understand the important of planning that includes detailed requirement analysis, feasibility analysis and identification of specification before initiating the project. Careful planning leads to successful, cost efficient and optimized accomplishment of the projects on time. Moreover, in order to accomplish the project successfully, it must be understood that “Deficient requirements are the single biggest cause of software project failure” [3]. Therefore, special concentration must be paid on proper planning and scheduling. This serves for the process control that “addresses the team's capability to execute according to plan” [3].

Now a days most carefully planned and designed software contains some defects. The Main aim of testing is to identify these defects. It also checks faults, errors, failures, and bugs in specific designed software. It requires creating and executing many tests. Software testing is the mensuration of software quality.

I. Introduction Functional Testing is basically testing software based on its functional requirements. Meaning it makes sure that the SUT (System Under Test) or program physically works the way it is intended. Now that there is a basic understanding of what Functional Testing is by the definition provided above; How about going more In-depth on the topic. This paper will provide answers to questions that the writer had on the topic as well as to the overall importance of Functional Testing.
