London Atil, let's discuss software testing now that we are aware of what a software developer works. Software is tested to make sure it functions properly by a software tester, also referred to as a quality assurance engineer. They develop test strategies, carry out tests, and document any problems or faults they encounter. An essential component of the development process is a software tester. Before the programme is made available to the general public, they make sure that it is operationally sound and that any problems are identified and fixed. Functional testing, usability testing, performance testing, and security testing are a few examples.

1. Difference between Software Developer and Software Tester
London Atil says while a software developer creates and develops software applications,
software tester ensures that it works as expected and meets the users' needs. London Atil,
Both roles are essential to the software development process, and they work together to
produce reliable, high-quality software products.
What is a Software Developer?
London Atil, let’s define what a software developer does. Simply put, a software developer
creates applications or software. Creating software, coding, testing, and maintenance are their
duties. They work on developing new software or updating existing software, depending on the
needs of the company or client they are working with. A software developer uses a variety of
programming languages, such as Java, Python, C++, and Ruby, to create software. They often
collaborate with designers, product managers, and other team members to ensure that the
software meets the needs of the user and the company.

2. London Atil, now that we know what a software developer does, let’s move on to software
testing. A software tester, also known as a quality assurance engineer, is responsible for testing
software to ensure that it works correctly. They create test plans, execute tests, and report any
issues or bugs they find. A software tester is an important part of the development process.
They ensure that the software is functioning correctly, and that any issues are found and
addressed before the software is released to the public. This can include functional testing,
usability testing, performance testing, and security testing.
Key Differences between Software Developers and Software Testers
Focus: Software developers focus on creating software, while software testers focus on
ensuring that the software works correctly.
Skill Set: Software developers need to have a strong understanding of programming languages,
software design, and user experience. Software testers need to have strong analytical and
problem-solving skills, as well as the ability to write and execute test plans.
Working Styles: Software developers tend to work in small teams, with each team member
contributing to the creation of the software. Software testers, on the other hand, work more
independently and often report directly to the development team.

3. Timeframe: Software developers work on creating software from the start to finish. It can take
months or maybe years to complete this. Software testers, however, typically work on a project
for a shorter period of time, typically during the testing phase.
Creativity: Software developers have more creative freedom, as they are responsible for
designing and creating software from scratch. Software testers, however, need to be
methodical and precise, as they are following predefined testing plans.
Conclusion
According to London Atil software development and testing are two different roles, each with
its own set of responsibilities and skills. While a software developer focuses on creating
software, a software tester focuses on ensuring that the software works correctly. Both roles
are important in the software development process, and it takes a collaborative effort to create
successful software that meets the needs of the user.
