New Specialization · AI & LLM Testing

Your AI product needs a
different kind of testing.

Standard QA can't catch hallucinations. Selenium won't tell you if your RAG pipeline retrieves the wrong context. We test what traditional QA misses — before your customers find it.

Why your AI product needs specialized testing

Standard QA techniques don't work for AI-powered software. Unit tests can't catch hallucinations. Your CI/CD pipeline has no idea how to evaluate whether a language model's output is factually correct, safe, or consistent.

Definition: LLM Testing

LLM testing is the practice of systematically evaluating the behavior, accuracy, safety, and reliability of applications built on large language models. Unlike traditional software testing — which checks deterministic inputs and outputs — LLM testing deals with probabilistic systems where the same prompt can produce different responses, and where failures manifest as subtle inaccuracies rather than hard errors. LLM testing covers hallucination detection, output consistency measurement, prompt injection security, contextual relevance evaluation, and performance under load. For SaaS teams building AI-powered products, LLM testing is not optional — it is the difference between a product that earns user trust and one that erodes it.

What we test

🧠

LLM Output Quality & Consistency

We measure whether your model produces accurate, consistent, and contextually appropriate responses — across different prompts, edge cases, and adversarial inputs. We quantify hallucination rates, output drift, and performance degradation over time.

🔗

RAG Pipeline Integrity

For retrieval-augmented generation systems, we test the full pipeline: document ingestion accuracy, embedding quality, retrieval relevance, context assembly, and final output coherence. A RAG system that retrieves the wrong documents will answer confidently — and incorrectly.

🤖

AI Agent Behavior & Safety

Autonomous agents that call external tools, make decisions, or operate with elevated permissions require specific testing for scope creep, unexpected behavior chains, and failure recovery. We define acceptance criteria for AI agents and test systematically.

🔐

Prompt Injection & Security

LLM-powered applications have a new attack surface: the prompt itself. We test for prompt injection vulnerabilities, jailbreak susceptibility, data leakage through model outputs, and unauthorized instruction following — covering the OWASP LLM Top 10.

⚖️

Bias, Fairness & Compliance

For AI products in regulated sectors (HR tech, fintech, healthcare SaaS), we test for systematic bias in model outputs and document findings in a format that supports GDPR and EU AI Act compliance requirements.

Performance & Latency

We establish baseline performance metrics for your AI features under realistic load — because a feature that works perfectly in demo conditions may degrade significantly when 500 concurrent users hit it.


The three layers of RAG pipeline testing

Testing a retrieval-augmented generation (RAG) system requires evaluating three independent layers: retrieval quality, context assembly, and generation accuracy.

Retrieval quality testing checks whether the right documents are retrieved for a given query — measuring precision, recall, and ranking relevance against a labeled test set.

Context assembly testing verifies that retrieved chunks are correctly formatted and passed to the model without truncation or corruption — a subtle failure that causes confident but wrong answers.

Generation accuracy testing evaluates whether the model produces responses that are grounded in the retrieved context, free of hallucination, and consistent across equivalent queries.

At QualityArk, we build custom RAG evaluation pipelines that combine automated metric scoring with human-in-the-loop review for edge cases — giving SaaS teams a repeatable, measurable quality bar for their AI systems.

How we find LLM security vulnerabilities

LLM security vulnerabilities are distinct from traditional software vulnerabilities and require specialized testing techniques. The primary attack vectors include: prompt injection, indirect prompt injection, jailbreaking, data leakage, and excessive agency in autonomous agents.

Finding LLM security vulnerabilities requires a combination of red-teaming (adversarial manual testing), automated fuzzing with adversarial prompt libraries, architecture review to identify over-permissioned tool calls, and output monitoring to detect anomalous responses. QualityArk conducts LLM security assessments covering the OWASP Top 10 for LLM Applications alongside custom threat modeling for each client's specific architecture.


Frequently asked questions about AI testing

Do we need to give you access to our model or training data?
Not necessarily. For most AI testing engagements, we work at the application layer — evaluating inputs and outputs — rather than requiring access to underlying model weights or proprietary training data. In most cases, black-box or gray-box testing is sufficient to identify the most critical issues.
We use a third-party LLM (GPT-4, Claude, Gemini). Can you still help?
Yes. Most of our testing focuses on how your application uses the model — the prompts, retrieval logic, output handling, and integration points — not the model itself. The same testing framework applies regardless of which LLM your product uses.
How is AI testing different from standard UAT?
User acceptance testing checks whether the software behaves as specified — a deterministic pass/fail check. AI testing evaluates whether the model behaves safely, accurately, and consistently across the full distribution of real-world inputs — which is fundamentally a probabilistic challenge. You need different metrics, different test datasets, and different evaluation frameworks.
Can you test our product for EU AI Act compliance?
Yes. We help SaaS teams understand their obligations under the EU AI Act and prepare documentation for high-risk AI systems. This includes risk classification, conformity assessment support, bias testing, and generating technical documentation that satisfies regulatory requirements.
How long does an AI testing engagement take?
The AI & LLM Sprint is 2–3 weeks from kickoff to final report delivery. Ongoing AI quality monitoring as part of a Quality Retainer can be embedded into your sprint cycles with no fixed end date. We can also scope a shorter 1-week assessment for teams that need a rapid pre-launch health check.
What is the difference between LLM testing and penetration testing?
Penetration testing focuses on traditional security vulnerabilities: SQL injection, authentication flaws, network exposures. LLM-specific security testing focuses on AI-native attack vectors: prompt injection, jailbreaking, data extraction through model outputs, and unsafe agent behaviors. We offer both independently and as a combined assessment for AI-powered products.
