A software development approach is a methodology that is
used to guide the processes involved in the development of a software system.
Different software development approaches provide different ways of organizing
and coordinating the activities and tasks involved in the development of
software. Some of the most common software development approaches include Agile
development, Extreme programming (XP), Lean development, Test-driven
development (TDD), and Waterfall model among many much more. These are just a
few of the many different approaches to software development. Each approach has
its own unique set of principles and practices that help guide the development
process and ensure the successful delivery of high-quality software.
Agile development is a software development approach that
emphasizes collaboration, flexibility, and continuous improvement. Extreme
programming (XP) is a software development approach that emphasizes
collaboration, simplicity, and feedback. Lean development is a software
development approach that emphasizes the elimination of waste and the
continuous improvement of processes. The Waterfall model is a software
development approach in which the development process is organized into
distinct phases, and each phase must be completed before the next phase can
begin.
Test-driven development (TDD) is a software development
approach in which tests are written for a new piece of code before the code
itself is written. The goal of this approach is to ensure that the new code
meets the required specifications and behaves as expected. In TDD, developers
write a test that defines the desired behavior of the new code, and then they
write the code itself. Once the code is written, it is run against the test to
see if it passes the test. If it does, the code is correct and is ready for
integration with the rest of the system. If it does not, the code is revised
until it passes the test.
I selected this
blog post because I am interested in learning more about Test-driven
development. After reading this blog post, I learned about the principles
and practices of TDD and how it can be applied in the software development
process. I also learned about the steps involved in TDD, including writing a
test that defines the desired behavior of new code, writing the code itself,
and running the code against the test to see if it passes. I found this process
to be logical and straightforward, and I can see how it would be a useful
approach for ensuring the quality of new code. I made use of this method (to a
degree) while working on the homework assignments for this class. I believe
that it significantly simplified the process as having a set goal in the form
of tests, made it easier to update/ add code that will work with it. Overall, I
found this blog post to be very informative and useful. I learned a lot about development
approaches, and I plan to use them for my future projects.
