Services / QA and Testing

QA and Testing Services

Independent quality assurance and testing for complex enterprise and government services — from strategy through automation to operational acceptance.

Nash QA and testing team reviewing release readiness together

Quality is engineered in, not inspected at the end. Our testers embed with your delivery teams, build the automation your release cycle needs and give leadership an honest, evidence-backed view of whether the service is ready to go live — and ready to be run.

What we do

Eight testing disciplines, one accountable team.

Consultants planning a test strategy around printed analytics

Test Strategy and Management

We set the quality direction before a single script is written — mapping business risk to test scope, defining entry and exit criteria, and shaping a delivery-ready test plan your programme board can hold us to.

Risk-based scoping and coverage modelling
Test governance, RAID and defect management
Environment, data and release planning
Live readiness reporting for programme leadership

E2E Testing Services

Real business journeys tested the way users actually work — across front-end, middleware, batch jobs and downstream systems, so integration gaps surface long before go-live.

Journey-led scenarios built with your service teams
Cross-system flows spanning SAP, portals and third parties
Functional, regression and exploratory testing
Traceability from requirement to executed test

Automated and Continuous Testing

Automation designed to outlive change. We build maintainable frameworks — Tricentis Tosca, Playwright, Selenium and Cypress — and wire them into your pipelines so every commit is checked, not just every release.

Model-based Tosca automation for SAP GUI, Fiori and SuccessFactors
Open-source frameworks for web, mobile and services
CI/CD integration with quality gates and fast feedback
Self-healing locators and reusable component libraries

Developer inspecting API responses across multiple monitors

API and Data Migration Testing

Contracts, payloads and records verified at the layer where most defects hide. We validate every interface and prove that migrated data is complete, accurate and reconciled before cutover.

Contract, schema and negative-path API testing
Performance and resilience checks on critical interfaces
Row-count, field-level and business-rule reconciliation
Mock services and virtualised dependencies for early testing

Business users running acceptance testing sessions together

SAP SIT and UAT Testing

Deep SAP specialism across SuccessFactors EC and Payroll, S/4HANA and EWM. We run system integration testing and steer business-led UAT with the structure, tooling and coaching that gets sign-off on time.

Parallel payroll runs, retro and FI posting validation
Business process validation across Finance, HR and Supply Chain
UAT facilitation, scripting and business user enablement
Half-yearly SuccessFactors release readiness testing

Accessibility Testing

Inclusive services, evidenced. We combine automated scanning with manual assistive-technology testing so your service meets WCAG 2.2 AA and stands up to a public sector accessibility audit.

WCAG 2.2 AA audits with prioritised remediation advice
Screen reader, keyboard-only and magnification testing
Accessibility statements and audit-ready evidence packs
Design and developer coaching to prevent repeat issues

Security analyst reviewing threat data on screen

Security Testing

Security defects found by us, not by an attacker. We test applications, APIs and SAP authorisations against real threat models and integrate scanning into the pipeline so protection holds as the product changes.

Application and API penetration-style testing
SAST, DAST and dependency scanning in CI/CD
SAP roles, authorisations and segregation-of-duties checks
Clear remediation guidance and retest verification

Operations engineer monitoring systems overnight

Operational Acceptance Testing

Proof the service can actually be run. We test backup and recovery, failover, monitoring, batch scheduling and support runbooks so day-one operations are rehearsed rather than hoped for.

Backup, restore and disaster recovery rehearsals
Failover, resilience and performance-under-load checks
Monitoring, alerting and runbook validation
Operational readiness sign-off with your service teams

How we engage

A delivery approach built for regulated programmes.

Assess

We review your current quality maturity, risks, tooling and release cadence.

Design

A pragmatic test strategy with scope, environments, data and automation targets.

Build

Frameworks, scripts and pipelines built alongside your delivery squads.

Execute

SIT, UAT, accessibility, security and OAT run with live defect and readiness reporting.

Sustain

Handover, coaching and managed regression so quality holds after go-live.

Why Nash

Testing that reduces UAT to go-live.

Risk-based prioritisation, reusable automation assets and AI-assisted defect triage shrink test cycles by up to 35% — without trading away coverage or evidence.
