Why are client company names anonymized in Qaston's public case studies?

Enterprise software testing and security assessments involve proprietary system architectures, pre-release roadmaps, and vulnerability findings governed by strict Non-Disclosure Agreements (NDAs). We publish anonymized architectural blueprints publicly and share referenceable details during NDA-covered consultations.

Can Qaston run a proof-of-concept (PoC) on our application before a full engagement?

Yes. We frequently start with a focused pilot—such as automating a critical user journey in Playwright, running an initial API contract and security audit, or building a baseline performance test script—so your engineering team can evaluate our code quality and reporting firsthand.

Do we retain full ownership of the test frameworks and scripts developed during an engagement?

Yes. All test plans, test cases, automation framework repositories, CI/CD workflow configurations, and execution reports created for your project are delivered directly inside your version-control and project management systems.

Software Testing Case Studies & QA Blueprints

FinTech & Digital Banking Web, Mobile & API Automation

Continuous Regression & API Contract Architecture for Multi-Tier Payment Workflows

Engineering Challenge: High-frequency sprint releases across web portals, mobile banking apps, and payment gateway microservices often suffer from slow manual regression cycles and breaking API schema changes between squads.

Technical Implementation Approach

Architected a modular Page Object Model (POM) browser suite in Playwright integrated with GitHub Actions pull-request quality gates.

Implemented consumer-driven contract testing using Pact and automated REST API regression collections via Postman and Newman.

Isolated parallel test execution with deterministic synthetic test accounts and automated trace capture on failure.

Retail & Omnichannel eCommerce Performance & Load Engineering

High-Concurrency Checkout, Inventory Locking & Flash-Sale Load Validation

Engineering Challenge: Seasonal promotional events and flash sales create sudden traffic spikes that expose database connection pool limits, cache stampedes, and third-party payment webhook timeouts.

Technical Implementation Approach

Modeled realistic user workload distributions (catalog browsing, cart updates, coupon validation, and checkout completion) using Apache JMeter and k6.

Executed stepped load, spike, and soak tests against staging clusters while correlating APM telemetry in Grafana and Prometheus.

Identified slow SQL queries, unindexed joins, and thread-contention bottlenecks prior to peak promotional windows.

Healthcare & Connected MedTech Security, Privacy & Compliance QA

End-to-End EHR Workflow, IoT Telemetry & Application Security Assessment

Engineering Challenge: Healthcare platforms handling protected health information (PHI) and connected medical device telemetry require strict functional traceability, role-based access enforcement, and vulnerability hardening.

Technical Implementation Approach

Designed requirements-traceable functional and UAT test suites covering patient onboarding, clinical workflows, and role-based access matrices.

Conducted OWASP Top 10 web and API security testing using OWASP ZAP and Burp Suite Professional to verify authentication, session controls, and BOLA/IDOR protections.

Validated synthetic test data masking pipelines so no production patient identifiers entered non-production test environments.

Enterprise ERP & CRM Ecosystems SAP S/4HANA & Salesforce QA

Cross-System Order-to-Cash (O2C) & Procure-to-Pay (P2P) Release Assurance

Engineering Challenge: Enterprise transformations linking Salesforce CPQ frontends with SAP S/4HANA finance and inventory backends face high cutover risk whenever custom code meets quarterly or seasonal vendor updates.

Technical Implementation Approach

Mapped end-to-end business process flows spanning lead-to-quote in Salesforce CPQ through sales order fulfillment, billing, and FICO posting in SAP S/4HANA.

Built reusable, data-driven automated test components for SAP Fiori/GUI transactions and Salesforce Lightning Web Components.

Established pre-cutover smoke and sanity packs alongside data migration reconciliation checks.

Enterprise Generative AI & Knowledge Assistants AI & RAG Pipeline QA

RAG Retrieval Precision, Faithfulness & Prompt-Injection Evaluation Pipeline

Engineering Challenge: Organizations deploying internal or customer-facing LLM assistants over enterprise knowledge bases need objective safeguards against hallucinated answers, stale retrieval context, and prompt-injection exploits.

Technical Implementation Approach

Curated a version-controlled golden evaluation dataset covering domain questions, multi-turn follow-ups, out-of-scope refusals, and adversarial prompts.

Automated retrieval precision, context recall, and answer faithfulness scoring using Ragas and Promptfoo inside CI.

Executed adversarial red-team suites testing system-prompt extraction, indirect injection, and cross-role data boundary enforcement.
