QA in the DevOps World

‍

Working to ensure quality in the world of software development is much more than just running tests before a production release. The role of QA or QE has evolved significantly—far from being limited to the final stage of the software lifecycle, it now spans the entire process end to end. This transformation affects not only how testing is done, but also the mindset required to guarantee quality in products that change, scale, and deploy in a matter of minutes.

We are in the era of automation, continuous integration, multiple daily deployments, and microservices. Quality can’t be a mandatory pit stop before a release—it must be present from the very first commit. This is where QA becomes a crucial piece of the DevOps puzzle and knowledge framework.

QA Is Not the End of the Road—It's the Common Thread

When we talk about QA in DevOps environments, we’re no longer just talking about "checking if everything works." Quality assurance becomes a strategic role that supports development from the start. QA gets involved in code and architecture decisions, understands how the product will be deployed, knows which tools are in play, and how pipelines are used.

Having a good eye for bugs or defining comprehensive test coverage in a particular environment is no longer enough. Today’s QA must understand the infrastructure the product runs on—what happens in each environment, how code flows from development to production, and how each change could impact the user experience. This holistic view allows for early anticipation, error prevention, and building quality from the ground up.

What Happens Behind Each Deploy?

In many teams, code is versioned and deployed daily to various environments. Knowing how to use GitHub or Bitbucket isn’t just for devs. Understanding how branches are managed, how merges are handled, and what exactly is being shipped in each pull request is essential for a QA who wants to keep up with today’s development pace.

Was there a hotfix? QA should know where it came from, what impact it has, which environment it’s going to, and whether it affects something that was already working. Knowing how code moves between environments—from testing to UAT to production—enables smarter, more focused test design. Most importantly, it provides context to determine what needs regression testing and what doesn’t.

Being familiar with the CI/CD pipeline is another key factor. When a feature is integrated, automated tests, quality validations, static code analysis, and more are executed. QA shouldn’t just know this is happening—they must understand how it’s configured, how to interpret results, and how to optimize these processes so that quality becomes a constant, not a roadblock.

Infrastructure and Environments: The Hidden Side (That Every QA Should Know)

To fully ensure quality, one must understand where what’s being tested is running. Is it running in a container? On which server? What database is in use? How do the microservices connect to each other? These questions used to fall solely to infrastructure teams, but today they’re part of the knowledge that empowers the modern QA.

Development, testing, staging, and production environments aren’t identical—but they should be as similar as possible to avoid surprises. Knowing how these environments are created and managed with tools like Docker, Kubernetes, or even Infrastructure as Code (IaC), allows QA to validate that what’s being tested truly reflects what the end user will see.

A great example is when a bug is found in UAT. If the QA knows how that environment is set up, they can investigate whether the issue is in the code, a misconfiguration, a bad branch merge, a difference from staging, or even a failed update. That technical analysis capability gives QA a huge advantage in solving problems quickly and collaborating more effectively with other teams.

Focus on Infrastructure

This new approach requires skills that go beyond clicking through the UI or backend. A technical QA is a mix of detective, developer, analyst, and, in many cases, systems operator. They not only need to know how to automate tests, but also read logs, interpret metrics, understand the code flow, and predict what could break when something changes.

Knowing how to automate isn’t enough without context. The same goes for regression testing—it’s not about rerunning the full test suite, but knowing exactly what needs to be validated. A QA with a DevOps mindset can access and read a PR, understand what module was touched, what services are involved, and which user paths might be affected. That saves time, improves test coverage, and prevents bottlenecks.

QA as a Technical Voice in Decision-Making

Another shift that comes with this vision is QA’s role in decision-making. Participating in dailies, retrospectives, and technical planning is no longer optional. QA doesn’t wait for instructions—they propose, ask questions, get involved.

When QA understands how a feature is deployed, how the infrastructure is structured, and what each change implies, they can give well-founded opinions. They can raise red flags early, suggest better testing strategies, or even recommend deployment process improvements.

It’s Not Just About Quality—It’s About Culture

The DevOps culture breaks down the walls that used to separate development, operations, and QA. Today, everything is interconnected, and within that mix, QA becomes the glue that holds it all together. But for that to work, a mindset of constant collaboration is essential.

QA must talk to developers—understand what they’re building and how. They must talk to the infrastructure team—learn how environments work. And they must talk to product—to know what the user wants. This ability to connect means QA doesn’t just find bugs—they prevent them, starting from the system’s very design.

At SWITCH, we believe in QA as a technical, curious professional with a global vision. It’s about moving beyond thinking of the "testing environment" as a black box and starting to look under the hood. It’s about getting involved, giving feedback, automating, breaking, and rebuilding.

A good QA in a DevOps team doesn’t just ensure quality.
They build it.
