Sayah ConsultingLet’s talk
Evidence before confidence

Write better tests.
Make releases easier to judge.

AI can propose scenarios, generate synthetic test data and explain failures. The evidence comes from executing the tests, reviewing the results and checking the journeys that matter to the business.

The challenge

A large number of tests is not the same as useful coverage. Payment safety, access controls, data correctness and recovery paths need deliberate cases and independent review.

What we can design and deliver

A defined scope.
A useful outcome.

01

Plans and acceptance

Risk-based test plans, missing-scenario reviews, traceable acceptance criteria and synthetic test data.

02

Application and API tests

Unit, integration, API and regression checks built around meaningful behaviour and error paths.

03

Browser and mobile journeys

Responsive layouts, key user journeys, device/browser coverage and visual regression checks.

04

Performance and security

Authorised load profiles, bottleneck analysis, abuse cases, dependency checks and code review.

05

Data and migration verification

Reconciliation, completeness, transformation and recovery checks against agreed acceptance rules.

06

AI system evaluation

Scope evaluation sets for grounded answers, permission boundaries, prompt injection, tool actions and human handover.

A controlled workflow

Clear steps. Visible decisions.

  1. 01Agree the risks
  2. 02Design the cases
  3. 03Generate and review tests
  4. 04Run and inspect evidence
  5. 05Approve the release

Engineers review test intent and results. Security and load tests run only within authorised scope. Agree the environments, workload, acceptance thresholds and release decision before execution.

Your delivery pack

What you take away.

  • Test strategy and critical-journey inventory
  • Executable test suite and synthetic data
  • Failure traces and reviewable reports
  • CI integration and release checks
  • Ownership and maintenance guide
Evidence from the pilot

What we measure.

  • Critical acceptance criteria exercised
  • Defects found before and after release
  • Flaky tests and maintenance effort
  • Performance against an agreed workload

Baseline, workload, scope and success criteria are agreed before the pilot. Results and savings are measured, not guaranteed.

Testing coverage

Choose the tests
that change the decision.

The engagement defines which testing types, environments and licences are in scope. The tools listed are options; we agree the right ones with you for each engagement.

Works with your environment.

A starting stack may include Playwright, Selenium, k6, pytest or Jest, OWASP ZAP, SonarQube and GitHub Actions. Alternative tools are assessed against the application and existing licences.
