The software is tested at different levels. Initially, the individual units are tested arid once they are tested, they are integrated and checked for interfaces established between them. After this, the entire software is tested to ensure that the output produced is according to user requirements. There are four levels of software testing, namely, unit testing, integration testing, system testing, and acceptance testing.

Code documentation is a manual-cum-guide that helps in understanding and correctly utilizing the software code. The coding standards and naming conventions written in a commonly spoken language in code documentation provide enhanced clarity for the designer. Moreover, they act as a guide for the software maintenance team (this team focuses on maintaining software by improving and enhancing the software after it has been delivered to the end user) while the software maintenance process is carried out. In this way, code documentation facilitates code reusability.

There are a few techniques available to verify that the detailed design is consistent with the system design. The focus of verification in the detailed design phase is on showing that the detailed design meets the specifications laid down in the system design. The three verification methods we consider are design walkthrough, critical design review, and consistency checkers.

Having test cases that are good at revealing the presence of faults is central to successful testing. Ideally, we would like to determine a set of test cases such that successful execution of all of them implies that there are no errors in the program. This ideal goal cannot usually be achieved due to practical and theoretical constraints.

For effective project monitoring, the information coming from the development process to the management process should be objective and quantitative data about the project. Software matrices are quantifiable measures that could be used to measure different characteristics of a software system or the software development process.

This methodology refers to a set of well-documented procedures and guidelines used in the analysis, design, and implementation of programs. Coding methodology includes a diagrammatic notation for documenting the results of the procedure. It also includes an objective set (ideally quantified) of criteria for determining whether the results of the procedure are of the desired quality. The steps to use coding' methodology are listed below.

There are two basic approaches to testing: functional and structural. In functional testing   the structure of the program is not considered. Test cases are decided solely on the basis of the requirements or specifications of the program or module, and the internals module of the program are not considered for selection of test cases.

A test oracle is a mechanism; different from the program itself that can be used to check the correctness of the output of the program for the test cases. Conceptually, we can consider testing a process in which the test cases are given to the test oracle and the program under testing.

Software Design: It is the first step in moving from problem domain to solution domain. The purpose of the design phase is to plan a solution of the problem specified by the requirements document. Starting with what is needed, design takes towards how to satisfy the needs.

Pure object-oriented development requires that object-oriented techniques be used during the analysis, design, and implementation of the system. Various methods have been proposed for OOA and OOD, many of which propose a combined analysis and design technique.
