Structural testing on the other hand is concerned with testing the implementation of the program. The intent of structural testing is not to exercise all the different input or output conditions but to exercise the different programming structures and data structures used in the program.

IEEE defines requirements analysis as (1) the process of studying user needs to arrive at a definition of a system, hardware or software requirements. (2) The process of studying and refining system, hardware or software requirements.' Requirements analysis helps to understand, interpret, classify, and organize the software requirements in order to assess the feasibility, completeness, and consistency of the requirements. Various other tasks performed using requirements analysis are listed below.

The rapid application development model emphasizes on delivering projects in small pieces. If the project is large, it is divided into a series of smaller projects. Each of these smaller projects is planned and delivered individually. Thus, with a series of smaller projects, the final project is delivered quickly and in a less structured manner. The major characteristic of the RAD model is that it focuses on the reuse of code, processes, templates, and tools.

In top down strategy we start by testing the top of the hierarchy and we incrementally add modules that it calls and then test the new combined system. This approach of testing requires stubs to be written. A stub is a dummy routine that simulates a module.

The term error is used in two different ways. It refers to the discrepancy between a computed, observed, or measured value and the true, specified, or theoretically correct value. That is error refers to the difference between the actual output of software and the correct output.

A software process as mentioned earlier, specifies a method of development software. A software project, on the other hand is a development project in which a software process is used. And software products are the outcomes of a software project.

The shift from traditional to object-oriented environment involves looking at and reconsidering old strategies and methods for testing the software. The traditional programming consists of procedures operating on data, while the object-oriented paradigm focuses on objects that are instances of classes. In object-oriented (OO) paradigm, software engineers identify and specify the objects and services provided by each object. In addition, interaction of any two objects and constraints on each identified object are also determined. The main advantages of OO paradigm include increased reusability, reliability, interoperability, and extendibility.

Once measures are collected they are converted into metrics for use. IEEE defines metric as 'a quantitative measure of the degree to which a system, component, or process possesses a given attribute.' The goal of software metrics is to identify and control essential parameters that affect software development. Other objectives of using software metrics are listed below.

In the software development process, requirement phase is the first software engineering activity. This phase is a user-dominated phase and translates the ideas or views into a requirements document. Note that defining and documenting the user requirements in a concise and unambiguous manner is the first major step to achieve a high-quality product.

In a top-down implementation, the implementation starts from the top of the hierarchy and proceeds to the lower levels. First the main module is implemented, then its subordinates are implemented, and their subordinates, and so on.
