Though the terms ‘software testing’ and ‘software development’ sound similar, they actually go on to mean
completely different things. However, both occupy great importance in the software industry and offer
great opportunities to those who are eager to make a career in the field. They come with their own set of
challenges, technical requirements, and experience and they are greatly needed in the industry. Here are
the major differences between software testing and software development:

Software development
Software development refers to computer programming that involves developing and maintaining a source
code in a structured manner. The concept involves an entire procedure to be followed to develop high-
quality and bug-free software, such as research, product development, prototyping, reengineering,
modification, reuse, and maintenance. Thus, a software developer caters to the functions of software
development as mentioned above.

Software testing
Software testing refers to the identification and verification of the computer software that has been
developed – the major elements being quality, correctness, and completeness. This process is followed to
check for any bugs or errors in the software so that those can be corrected before it is delivered and
deployed to the end users. Software testers ensure that the product results match with the expected
results and that the system is error-free under controlled situations. Apart from identifying defects and
solving them, software testing companies in India analyze a particular software to check the differences
between the ideal and existing conditions.

Major Differences between Software Development and Software Testing
Software development focuses on developing the code and testing so that it fits the requirements, while
software testing is about testing the developed software under controlled circumstances to ensure that
only high-quality product reaches the clients and users.

Software development is known by several other names such as software design, software application
development, platform development, application development, and enterprise application development –
all of which mean the same thing and are performed by software developers. On the other hand, software
testing is done by software testers who are professionally trained to execute programmes and find defects
in the product before final delivery.

Software development involves the developer, publisher, system development timeline, and programmer

or coder. Software testing involves the tester, test lead, test administrator, manager, test designer, and test
developer.

Now that you know the difference between software development and software testing, you need to look
for the right organization for your purpose.
