Pair
programming
One of the recommended approaches in the agile method ‘eXtreme Programming’ is called pair
programming. In this
technique, two programmers
always work
together in front of a single computer.
The idea is that their constant
interaction should stimulate good ideas and prevent errors.
Whether this approach should
be widely adopted is still being studied and debatedOne of the objectives of
software engineering researchers has been to automate programming. There
has been some success in this regard
– some tools now generate
much of the code for you from models typically represented in UML.
However, there
will always be a need
for some programming done by humans.
We assume
that readers of this book have some object-oriented program- ming background. We will
use Java for the
example code in this book,
and you will be asked
to translate designs
into programs so you can get a feel for the
effects of various
design decisions. If you know an object-oriented language other than Java (e.g.
C++, C# or Smalltalk) it should not be difficult to learn enough Java to use the book effectively.
Quality assurance
Quality assurance (QA) encompasses all the processes needed to ensure that the quality objectives discussed in Section 1.5 are met. Quality assurance occurs throughout a project, and includes many activities, including the following: Reviews and inspections. These are formal meetings organized to discuss requirements, designs or code to see if they are satisfactory.
<!--[endif]-->Testing. This is the process of systematically executing the software to see if it
behaves as
expected.
Quality assurance is also often
divided into validation, which is the
process of determining whether the requirements
will solve the customer’s problem,
and verification, which
is the process of making
sure the requirements have been adhered to.
In various
chapters, we present
checklists that you can use to conduct
reviews. Testing and some other aspects of quality.
Deployment
Deployment involves
distributing and installing the software and any other
components of the system such as databases, special hardware etc. It also
involves managing the
transition from any previous systemRelated Articles
