Studio — Performance & NFR Assurance

The complete NFR governance and performance testing platform. Two components working together: a SaaS dashboard for NFR management, results analysis, and sign-off governance, plus a standalone execution framework deployed in your Azure subscription for distributed load testing.

  • Master NFR templates with placeholder-driven generation and 5-stage lifecycle
  • JMeter JTL upload with automated parsing, percentiles (P90/P95/P99), and error RCA
  • Auto-evaluation of test results against NFR thresholds
  • Token-based sign-off workflows, release tracking, and compliance reporting
  • 8 report types with Excel export: compliance, coverage, trends, matrix, and more
  • AI support agent for framework guidance and troubleshooting
  • Available as SaaS or standalone dedicated deployment
Execution Framework

Distributed Performance Testing

A portable, Azure-native load testing framework deployed into your own subscription. Paired with the Studio dashboard for end-to-end NFR governance.

JMeter Distributed Testing
Apache JMeter master + auto-scaling worker VMSS. Scale from 0 to N load injectors on demand. Thread-count-aware parsing with automatic ramp-up detection.
14-Step Analysis Pipeline
Automated results analysis: JTL parsing, percentile calculations, NFR threshold evaluation, error RCA grouping, infrastructure metrics collection, and report generation.
Infrastructure as Code
Full Terraform + Packer deployment. VNet, NSG, Key Vault, SQL Server, shared storage, and self-hosted Azure DevOps agents — all provisioned automatically.
Mock Services & Auth
Built-in generic mock service with OIDC and Entra ID token endpoints. Test against mock APIs with configurable latency, response codes, and authentication flows.
Pipeline Execution Flow
Prepare → Scale Workers → Seed Data → Smoke Test → Execute → Analyse → Archive → Teardown

Built from Experience

Paul Lewis

Founder

Over 35 years in IT, from mainframes to cloud-native architectures. The CEIUS framework emerged from leading performance engineering teams at NHS Digital, DWP, and MOJ, where the cost of missed requirements meant failed tests, blown budgets, and uncomfortable conversations.

Contexta Studio grew from the same experience — a structured, opinionated approach to NFR management and performance testing that gives teams a proven governance framework from day one.
