Testing With AI. Testing AI-powered products, and using AI to test faster with fewer escaped defects. We validate your AI products and features for accuracy, hallucinations, bias, and prompt robustness with a framework built for non-deterministic systems. And we bring AI into how we test everything else — risk-based prioritization, test-data generation, and flaky-test detection that take regression from days to hours. * * * \> 60% Fewer AI Hallucinations Validated output quality on B2B sales copilots — cutting irrelevant and unsafe responses. \> 35% Higher Response Accuracy Structured scoring across quality, safety, and tone lifted accuracy on generated content. \> 160+ AI Edge-Case Prompts A reusable library of edge-case prompts stress-tests your AI for bias, tone, and failure modes. ## Real Projects, Impactful Results: QA and AI Testing Cases AI Testing for a B2B Sales Copilot **Problem.** A sales copilot designed to automate email drafts was generating irrelevant, unprofessional, and sometimes biased content, leading to low user adoption. **Solution.** We implemented a custom testing framework focused on prompt engineering, output validation, and bias detection.  Our team created a comprehensive library of edge-case prompts and a scoring system to evaluate the quality, safety, and tone of the generated content. - Over 60% reduction in hallucination rate - Over 35%  improvement in response accuracy - Eliminated key instances of gender and racial bias - From 6.5 to 8.7 average user satisfaction rating growth. ![](https://testfort.com/wp-content/uploads/2025/10/il_AI-Testing-for-a-B2B-Sales-Copilot-1.png.webp) QA for an E-commerce Recommendation Engine **Problem.** An e-commerce platform’s recommendation engine was providing irrelevant product suggestions and its performance was degrading over time due to model drift and poor data quality. This resulted in a over **20% drop in click-through rates**. **Solution.** We developed an automated regression testing pipeline that monitored the model’s performance on live production data. Our data validation strategy identified and rectified data quality issues, and we set up continuous monitoring to prevent future drift. - From 6.5 to 8.7 average user satisfaction rating growth - 95% model accuracy validation - Restored click-through rates to pre-drift levels - Identified 2 critical data leakage risks. ![](https://testfort.com/wp-content/uploads/2025/10/Cases-page-eCommerce-Recommendation-487-%C3%97-383.png) AI Quality Audit for a CI/CD Assistant **Problem.** The client’s AI assistant for CI/CD workflows struggled with accuracy, adaptability, and security, often producing hallucinated or inconsistent responses and failing to deliver proactive, context-aware support. **Solution.** TestFort conducted a full AI quality audit using manual, automated, and usability testing to identify weaknesses and implement a continuous monitoring and regression testing framework. - 20% increase in user satisfaction - 25 critical AI defects identified - 60% reduction in hallucinations - 17% higher reply accuracy ![](https://testfort.com/wp-content/uploads/2025/10/Cases-page-Idera-Travis-AI-case-illustrations-487-%C3%97-383.png) AI-Powered Testing Boost for Creative Console Builder **Problem.** The client’s QA process struggled with duplicated bugs, limited test coverage, and inefficient reporting, slowing down releases and damaging overall QA efficiency. **Solution.** TestFort applied AI tools like DeepTriage, ChatGPT, and Power BI to automate bug triage, enhance test coverage, and accelerate reporting while maintaining data security and smooth integration. - 80% faster bug report creation - 80% faster test case generation - 40% broader edge-case coverage - 50% more accurate documentation ![](https://testfort.com/wp-content/uploads/2024/11/Cases-page-AI-Enhanced-Testing-for-Creative-Console-Systems.png) ## Prefer to just talk it through?

Yes. Larger organizations come to us for mature, audited processes — CMMI Level 3 and ISO 27001 — and the ability to stand up a dedicated QA team that plugs into existing SDLC and compliance requirements. We’re used to structured environments, formal documentation, and regulated industries like fintech, banking, and healthcare. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) Do you work with startups? Absolutely — a large share of our clients are startups and scale-ups. When you’re moving fast, we help you catch critical issues before they reach users, set up automation early so quality scales with you, and start small without committing to a big in-house QA hire. You get senior QA expertise without the headcount. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) Do you test AI products? Yes — it’s one of our core strengths. We test LLM apps, copilots, and AI agents for the things traditional QA misses: accuracy, hallucination rate, bias, prompt robustness, and output safety. It runs on a dedicated AI testing framework built for non-deterministic systems, backed by AI security practices that keep these products safe and compliant. On a recent B2B sales copilot, we cut hallucinations by 60% and lifted response accuracy by 35%. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) What engagement models do you offer? **Fixed-Cost Packages** — a defined scope and budget, best for regression suites, release hardening, migrations, or compliance sprints; you get a test plan, automated suite, coverage dashboards, and handover docs. **Dedicated Team** — an embedded QA squad (QA leads, automation and manual engineers, performance/security as needed) that works in your sprint cadence for ongoing quality. We’ll recommend the model that fits where you are. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) Do you offer fixed-price projects? Yes. If your scope is clear, we’ll quote a fixed price with defined deliverables and timelines — so you have budget certainty up front, with no open-ended billing. For evolving or long-term work, a dedicated team is usually the better fit, and we’ll tell you honestly which one suits your project. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) What kind of commitment do you need from us? As little as you’re ready for. Most engagements start with a **free QA audit** — no commitment — so you can see the value before signing anything. Fixed-cost projects are scoped and time-boxed. Dedicated teams run on flexible terms rather than long lock-ins, and because you own every test asset from day one, you’re never tied to us to keep your QA running. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) Can you cover project management too? Yes. Our dedicated teams include QA leads who own test planning, coordination, and reporting, so you don’t have to manage the testing process day to day. We integrate with your PM tools and cadence and give you a single point of contact — useful when your team is lean or QA isn’t your core focus. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) How quickly can you start? Typically within about 10 days from first conversation to active testing. A free QA audit can begin even sooner and gives you a concrete picture of risks and quick wins before any commitment. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) What types of software do you test? We do full-cycle: web & web apps, mobile, desktop, CMS/ERP/CRM, IoT, cloud, games, and AI products. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) What tools and methodologies do you use? Agile/Lean/Waterfall/V-model to match your SDLC; Selenium, Appium, Jenkins + AI-powered tools like Virtuoso AI; emulators and real devices. ![](https://testfort.com/wp-content/uploads/2022/01/faq_block_one_white_title.svg) Do you provide QA documentation? Yes: test plans, strategies, cases, traceability matrices, summary reports; refined over 25 years so you can switch vendors or go in-house cleanly. ## Latest news and Insights ![](https://testfort.com/wp-content/uploads/2022/01/get_in_touch.png) ## Ready to start testing?
