What we ship

Six concrete deliverables.

Every QA & Automation engagement maps to a specific deliverable below. We commit to it in the SOW, demo it weekly, and you own the result.

01

E2E test suites

Playwright + Cypress. Stable across browsers, fast in CI, run in parallel, deterministic.

QA & Automation
02

Unit + integration

Vitest, Jest, PyTest, Go test. Coverage thresholds gated in CI.

QA & Automation
03

Performance

k6 + Gatling for load. Web Vitals budgets in CI. Synthetic monitoring after deploy.

QA & Automation
04

Visual regression

Percy + Chromatic. Catch the unintended pixel change before it ships.

QA & Automation
05

Accessibility

axe-core, Lighthouse, Pa11y. WCAG 2.1 AA audits + keyboard walk-throughs.

QA & Automation
06

Test infrastructure

Parallel runners, sharding, flake detection, test analytics. Tests stay fast as you grow.

The stack

The tools we reach for.

Solid line: what we use every day. Dashed line: what we reach for when the brief justifies it. We will work in your stack if you have a strong reason; otherwise these defaults serve us well.

How we engage

Four steps. Real demos every Friday.

From signed SOW to first demo is one week. No discovery loops that bill for months without showing software. No silent stretches between status decks.

01

Audit

Current test landscape, flake rate, CI duration, coverage gaps. Output: priority backlog.

Week 0-1
02

Foundation

CI config, parallel runners, base Playwright + Vitest projects.

Week 1-2
03

Coverage

Critical user journeys covered E2E. Unit coverage to threshold. a11y baselines set.

Week 2-6
04

Retainer

Ongoing test maintenance, flake reduction, performance budgets.

Ongoing
CI went from 28 minutes to 6 minutes. Flake rate is under 2%. Devs now actually run the tests locally.

Frequently asked

The questions buyers ask first.

How much should we invest in tests?
Enough that the team trusts the suite. If devs are skipping CI or pushing through reds, the suite is broken. Our default split: 70% unit, 25% integration, 5% E2E on critical journeys.
Playwright or Cypress?
Playwright by default. Multi-browser, multi-language, faster, official Microsoft maintenance. Cypress is a fine choice if your team already knows it.
Do you do accessibility audits?
Yes. WCAG 2.1 AA, screen-reader walk-throughs, keyboard nav verification, contrast checks, focus management review. Output: prioritized fix list with engineering specs.
Performance budgets?
Yes. Web Vitals baselines, Lighthouse thresholds gated in CI, k6 load profiles. Performance regressions block merges, not just generate warnings.

Frequently asked

Quick answers.

The questions buyers in this service ask in week one.

What's in your test pyramid?+

Unit (Vitest/Pytest), Integration (testcontainers), Contract (Pact), Component (Playwright), End-to-end (Playwright sharded), Visual (Percy/Chromatic), Performance (k6), A11y (axe), Mutation (Stryker).

Coverage requirements?+

80% line coverage on new code as hard CI gate. 95% with 70%+ mutation score on critical paths.

Do you support WCAG 2.1 AA?+

Yes. Manual + automated. VPAT delivered as project artifact. Section 508 for federal customers.

Performance testing?+

k6 with thresholds wired to CI. Budgets per request path. Synthetic monitoring post-launch.

Can you take over an existing test suite?+

Yes. Audit identifies flaky tests, gaps, and brittle patterns. Stabilization sprint before adding coverage.
