Proven, world-class, state-of-the-practice software testing services built on a patented Keyword Test Automation framework. Trusted by Startups and Fortune 500 organizations for 30+ years.
Startup to $30B+, we host solutions from industry builders to industry titans.
SDT delivers end-to-end software testing powered by our patented framework — so your releases ship on time, production bugs stop escaping, and your automation actually scales without ballooning maintenance costs.
Missed release windows. Defects reaching production. An automation suite that nobody trusts — and costs a fortune to maintain. These aren’t just QA problems. They’re business problems that slow growth, damage customer trust, and drain engineering capacity.
SDT solves the root cause. We replace fragile, script-heavy test cases with Keyword-Driven Test Automation built for speed, reuse, and long-term maintainability — using your existing technology stack and open-source tools so costs stay under control.
Utilizing our SDT IP Library, we build reusable building blocks (Keywords) to ensure rapid test development and low-effort maintenance.
Validating that your applications meet expectations for speed, scalability, and stability under load.
Rigorous testing to ensure your software and APIs meet the highest expectations for security and reliability.
Comprehensive testing to ensure your products are usable and compliant for all users.
SDT has helped companies across healthcare, finance, aerospace, retail, and technology and many more transform their software quality — on time and at scale. But don’t take our word for it. Hear directly from the teams we’ve partnered with.
SDT’s patented Keyword Test Automation framework is the foundation of every engagement we run. Test cases are designed in plain business language — no scripting required from your QA team.
SDT handles all automation engineering underneath.
Test cases are written using Keywords that represent real business flows — readable by anyone on your team, not just engineers. Test Designers define coverage. Automation Engineers implement it. The roles are separate, and that separation is what makes the framework maintainable.
SDT selects and integrates the best-in-class available testing tools for your environment. No tool purchase required. No vendor lock-in. The Keyword framework operates across your existing stack.
The regression library wires directly into your existing CI/CD pipeline — so automated regression runs on every build, every deployment, without manual trigger or human sign-off.
Keyword reuse ensures fast development, efficient methodology and practice, and easy maintenance.
SDT's framework leverages AI to keep your test library healthy and coverage sharp. Self-healing keywords adapt automatically to application changes, while AI-driven anomaly detection flags failures before they reach production — reducing maintenance overhead and making every regression cycle smarter than the last.
This enables technical and non-technical stakeholders to contribute to test creation while dramatically lowering maintenance costs.
SDT partners with the most proven tools in the industry — and works with proprietary ones when off-the-shelf solutions fall short. At the heart of our approach is Keyword-Driven Test Automation, a powerful methodology that separates test design from test automation implementation, allowing teams to build, manage, and scale automated test suites without deep scripting expertise.
By using modular, reusable keyword components, our frameworks dramatically reduce maintenance costs, accelerate test development, and put quality control in the hands of your entire team.
Paired with leading open-source and commercial tools, our approach covers every technology platform — Web, API, Mobile, Mainframe, and beyond — so your software is tested thoroughly, efficiently, and at scale.

A test automation library is only as strong as the framework underneath it. Without a dynamic, globally-structured framework, every application change triggers a wave of manual rework. Your team spends more time keeping tests alive than building new coverage. Static frameworks break as your codebase evolves Test assets can't scale across platforms or releases No structure means no repeatability — and no ROI Maintenance cost grows faster than coverage does
Scripted testing looks like automation, but without a keyword-driven approach it becomes an unmanageable tangle. Test code grows longer than the product it covers, because you have to test every angle of every change. Without proper architecture, it's impossible to unwind. Scripts are fragile — one change breaks dozens of tests The test library grows larger than the product itself Too much code, too few engineers who understand it Trust in test data collapses — so humans still approve releases No keyword structure means no clean path forward
Modern codebases demand a world-class framework, not a patched-together script library. SDT builds the automation infrastructure that matches the complexity of what you're testing — and then uses AI to keep it healthy. Self-healing keywords adapt as your UI and APIs change AI-assisted KT sessions: record your codebase walkthroughs, feed to AI, generate full test case sets AI queues test cases and maintains the library automatically Most teams are still scripting manually — SDT uses AI to engineer it better The data you could capture is infinite — SDT helps you engineer it right
When release cycles stretch past their target, the conversation usually starts with development velocity. The real drag is almost always QA — manual regression sign-offs, test suites that need babysitting before every build, and an automation library that adds overhead instead of removing it. Every week a release slips is a week of revenue, competitive position, and team confidence you don't get back.
· Manual regression sign-off holds every release hostage to someone's availability
· Brittle test suites require rework on every build — adding days to every cycle
· No CI/CD integration means regression is a gating event, not a continuous one
· Slow QA cycles compound — delayed features, missed market windows, eroded trust
· Teams work around the testing bottleneck instead of fixing it — and it gets worse every release

The MMC case study features Fred Berkowitz, VP of Development, as the direct buyer and champion. This role owns engineering quality, has headcount budget, and is accountable for product delivery. The copy could speak to needing confidence in test coverage without scaling their team.
You own the testing organization — and when releases slip, the responsibility lands on you. SDT helps you modernize your testing practice from the ground up, introducing keyword-driven frameworks that upgrade your coverage and process without requiring a full rewrite of your existing environment.
You need release confidence that doesn't require a manual sign-off. SDT builds regression libraries powered by AI, promoting healthy, maintainable environments that keep your test assets accurate, current, and ready to scale.
You’re evaluating whether your testing organization can scale with the product. SDT’s methodology is documented, patented, and transferable — it doesn’t walk out the door when a contractor leaves.
Most testing approaches trap teams in complex scripting cycles — where building a test requires an engineer, maintaining it requires constant rework, and scaling it requires starting over. SDT’s approach was engineered from first principles — and protected by a U.S. patent. The Keyword framework separates test design from automation engineering, freeing your team from script dependency and producing regression libraries that stay maintainable as your software grows. AI reinforces that maintainability — continuously optimizing your regression library so your test assets remain healthy, accurate, and ready to scale.
Engineered from first principles — not assembled from borrowed tools. The patented Keyword framework is the foundation everything else builds on.
Your QA team designs coverage. SDT engineers implement automation underneath. The separation is what makes the framework maintainable at scale.
