The team worked in software development and testing had to
deal with a certain type of specification requirements when undertaking a new
project. precise requirements and well defined need for software development
teams to work on the creation of the proper application and documentation have
made the overall development process easier.
There are various kinds of specification requirements, but
now, we will explain the three types of primary documents used exclusively in
software testing. This is a BRD (Business Requirements Document), FRD (document
functional requirements), and SRD (Software requirements document). It should be
noted that all these documents are used depending on the types of companies,
standards, and organizational processes. Further down, we will provide further
details on each of these documents and explain the main differences between the
FRD and SRD documents and differences between BRD and the FRD in software
testing.
Terms of Business Documents
BRD stands for business requirements document is intended to
show how to meet business requirements on a broader level. A document BRD is
one of the specification document most widely accepted. This is quite
important, and BRD are usually made at the very beginning of the life cycle of
the project and define the core project objectives or needs of the client is
willing to achieve with a particular software or platform. This one is usually
made by the business analysts based on the end user specifications and after a
thorough analysis of the company. Typically, the final version of the document
to be reviewed by the end client to ensure that all business stakeholders
expectations are listed correctly.
A BRD covers all the requirements wished by the client. Typically,
it consists of the application of interest, the user, complete the scope of
work, all registered quality and functionality, usability and performance
requirements. A BRD is used primarily by upper and middle management, project
sponsors and business analysts.
Functional Requirements Document
A FRD or functional requirements document is an artifact
that defines all the functions of the software or application should do. In
fact, the structure of the step-by-step all the operations necessary to develop
a product from start to finish. A FRD explain the details of how a particular
software component will behave during user interaction. The main difference,
compared with SRD document, is that FRD not including use cases. It may also
contain diagrams and tables, but this is not mandatory.

FRD to understand what they are supposed to make the application, and software
testers to get a better understanding of different test cases and scenarios in
which the product is expected to be tested.
Software Requirements Document
SRD or Software Requirement Document is a document prepared
by a team of analysts who are used to define the system software to be
developed, the main business purpose and function of certain products and the
way how to perform its core functions. A SRD is the basis for every project as
it consists of a framework that will be followed by each member of the project
team. A SRD is also the basis of a contract with the stakeholders (users /
clients) that includes all the details about the functions of the future
application and how it should be run. A SRD widely used by software developers
for the product or program development.
A SRD includes functional requirements and non-functional
and use cases as well. A perfect SRD document considers not only the software
how to interact with other software or when it is embedded in the hardware, but
also potential users and the ways they interact with software. It also contains
references to tables and diagrams to get a clear understanding of all the
details associated with the product. A document SRD help team member from
different departments at the same fixed and make sure all requirements are met.
This document also allows to minimize software development costs and time.
