Software Testing And White Box 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

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

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

Testing – Testing shows the material practiced, learned and the recall process. The limitations of testing are static analysis as well as model checking. Tests are not always better than re-studying.

An acceptance test is the process of the user testing the system and, based on the results, either granting or refusing acceptance of the software/system being tested. It is often referred to as functional testing, beta testing, quality assurance (QA) testing, application testing, or end user testing. [26]

In data flow testing, the program graph for the software component under test is further analyzed. Data flow

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. (Referenced from Software Engineering - A Practitioner 's Approach by - Roger S. Pressman).

Software and software-based systems testing is a technical discipline of systems engineering. The purpose of software and software-based systems testing is to help the development organization build quality into the software and system during the life cycle processes and to validate that the quality was achieved. The test process determines whether the products of a given life cycle activity conform to the requirements of that activity, and whether the product satisfies its intended use and user needs. This determination can include inspection, demonstration, analysis, and testing of software and software-based system products. Test activities are performed in parallel with software and system development, not just at the conclusion of the development effort.

This report is going to explain my opinion on how testing software has the ability to significantly improve the quality. I have read certain books that give different reasons for the purpose of testing and how well it actually improves the software, and will reference these as I use them throughout the report. Firstly my opinion on testing is that from experience, I have found testing to help greatly towards improving the quality of the software as it basically breaks down the frame and structure of the software which allows you to see every single line of code in detail and gives you a different perspective so that you can decide what you can do exactly in order to improve the quality. “Software Quality is something everyone wants. Managers know that they want high quality, software developers know they want to produce a quality product, and users insist that software work consistently and be reliable.” (William E. Lewis, 2004)

The main aim of software development is to produce high quality software. Superior quality software has characteristics like low cost, reliability and user satisfactory. Software testing is the process of assessing the software in order to discover any defects and determine if the software satisfies all the requirements. It is a step by step process of planning the requirements, executing the program and finding any defects to verify that the program meets its required

“Software Testing is a process of evaluating a system or its components with the intention of checking whether the system developed satisfy the requirements. Testing is done for finding gaps, errors, or missing requirements causing hindrance to systems functionality”.

There are two fundamental purposes of testing they are verifying procurement specifications and managing risk. First, testing is about verifying that what was specified is what was delivered it verifies that the product meets the functional, performance, design, and implementation requirements

To provide an overview of the various tools and techniques available for software testing, the coursework comprised of five assignments. Each assignment was to study, how to use an existing testing tool or technique to aid the process of verification and validation of the software.

Software testing is a technical task, but it also involves some important considerations of economics and human psychology. In technical aspects it is the process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item”. A software error occurs when the program does not do, what its end user reasonably expects it to do.

Introduction: Software testing is a very important part of software development process. Software testing is a very important part of software development process. Software testing is analysis of a system by giving defined inputs and contrasting them with the desired outputs to check the errors between the desired and actual outputs and correct them. Essentially software testing can be separated into two classes manual testing, automated software testing.
