QA Testing and Software Development: Critical Tech Roles

When you think about working in the tech world, the first role that comes to mind is likely a software developer. And indeed, software developers play a crucial role in innovation and technological advancement. But they are not the only important specialists in the tech industry. In addition, testers and related quality assurance (QA) professionals play a vital role in the software development lifecycle (SDLC).

Both professions are highly lucrative—according to the Bureau of Labor Statistics (BLS) as of May 2023, software developers and software quality assurance analysts earn an average of 1 million rubles per year (median 50%). And while individuals with similar educational backgrounds (especially those inclined toward math, engineering, and computer science) pursue both roles, these positions involve different responsibilities, accountability, and skill sets.

So, what roles do QA testers and software developers play in the SDLC? And why are they so important? Let’s explore their differences and significance.

Roles of Software Developer and QA Tester

What sets developers apart from testers? Here’s a brief overview of each of these important roles.

Software Developer

Using a variety of tools and skills, software developers create products such as mobile and web applications according to requirements set by clients, employers, or other stakeholders. This role demands extensive knowledge and experience with programming languages and related programming tools like frameworks and environments.

During product development, developers perform basic testing, including unit testing, to ensure proper software functionality. Although developers are expected to identify and fix errors that clearly hinder core product functionality, their role does not include thorough testing and resolution of more subtle defects.

Software development involves more than just writing code. Depending on the specific developer role, they may be responsible for designing and prototyping software, as well as analyzing requirements to determine if and how they can be met.

QA Software Tester

QA testers are not involved in creating software, but they still play a vital role in its lifecycle. As the name suggests, these professionals test software to ensure the product meets specified requirements. There are many different types of testing that assess functionality, performance, usability, capacity, load and stress tolerance, security, and more.

The QA process typically involves a combination of automated and manual testing. Even with automation, a QA specialist must write the test script to be automated. Ultimately, the goal of this process is to ensure the product is as defect-free as possible and ready for end users.

It is important to note that no product can be declared completely bug-free, nor is that the goal of QA testing. Rather, QA professionals catch as many bugs as possible and report them to developers for resolution. If defects are discovered after product release, developers fix them in the next release.

To create a high-quality product and ensure its readiness for market, the development team and QA team must work closely together. Collaboration is essential for every role in the SDLC, perhaps none more so than for these two positions.

While most testing is sometimes conducted at the end or near the end of the development phase, software can also benefit from earlier testing. This allows testers to identify critical defects that hinder functionality and quality early on, before developers invest too much time and effort building the product.

Possible Career Paths

Software development and testing are not standalone professions. Within each field, there are many possible career paths. Here are some of the main developer and tester roles. Note that this list is not exhaustive.

Software Development

• Frontend Developer
• Backend Developer
• Full Stack Developer
• Mobile Engineer
• Web Developer
• Application Developer
• Game Developer
• Data Scientist
• DevOps Engineer

QA Testing

• QA Analyst
• QA Engineer
• Software Test Engineer
• Functional Tester
• Automation Engineer
• Manual Tester
• QA Manager
• Test Architect

One role spans both worlds: the Software Development Engineer in Test (SDET). SDETs create software for QA testing, including automated tests, test code, frameworks, and other tools. Like other roles in these lists, they play a key part in the SDLC.

Skill Sets

There are many overlapping skills that both software developers and QA testers need. However, some skills are more essential to one role than the other. Below are just a few of the many skills required for each role. Note that some skills appear twice as they are mandatory for both groups.

Software Developer

• Programming
• Creativity
• Problem Solving
• Communication
• Attention to Detail
• Adaptability
• Logic
• Multitasking
• Curiosity
• Focus
• Teamwork

QA Tester

• Analytical
• Interpersonal
• Communication
• Attention to Detail
• Organizational
• Efficiency
• Sound Judgment
• Critical Thinking
• Agility
• Data Analysis
• Teamwork

It's clear that both software developers and QA testers play a critical role in creating high-quality, user-friendly software, regardless of their specific job titles. But each requires unique skills and responsibilities. If you are considering a career in tech, think carefully about where your strengths lie.

Also remember that these are just two of many opportunities in the software and technology world. There are numerous roles requiring diverse knowledge and skills—from information technology (IT) to technical writing and project management—you just need to find the right niche for you.
