Quality

QA that catches bugs
before your users do

Playwright, Cypress, Jest, and k6 — we build automated testing strategies that give your team confidence to ship fast without sacrificing quality.

What we build

QA & testing services

From unit tests to load testing, we build quality into every stage of your pipeline.

01 / E2E

End-to-End Testing

Playwright and Cypress tests that simulate real user journeys — login, checkout, edge cases — running in CI on every pull request.

  • Playwright with auto-waiting & tracing
  • Cypress for component & E2E tests
  • Page Object Model for maintainable tests
  • Visual regression with Percy / Argos
02 / Unit & Integration

Unit & Integration Tests

Jest, Vitest, and pytest for fast, focused tests that verify business logic — running in seconds, not minutes.

  • Jest / Vitest for JavaScript/TypeScript
  • pytest with fixtures & parametrize
  • Test doubles with MSW for API mocking
  • Database integration tests with testcontainers
03 / Performance

Load & Performance Testing

k6 and Artillery scripts that simulate production traffic patterns — find bottlenecks before launch, not during Black Friday.

  • k6 load tests with realistic scenarios
  • Stress testing & soak testing strategies
  • Performance budgets in CI/CD
  • Core Web Vitals monitoring & alerting
04 / Strategy

QA Strategy & Automation

Testing pyramids, flaky test triage, and CI optimization — we help teams test smarter, not just test more.

  • Testing pyramid design & implementation
  • Flaky test detection & quarantine systems
  • Test data management & seeding
  • CI parallelization & sharding strategies

Use cases

QA in practice

E-commerce checkout testing

Playwright test suite covering 47 checkout scenarios including coupon codes, split payments, address validation, and inventory race conditions — running in 4 minutes on CI.

API regression suite

Comprehensive API test suite with 600+ scenarios validating request/response contracts, error codes, pagination, and auth flows — catching breaking changes before merge.

Mobile app testing

Detox and Maestro test suites for iOS and Android covering onboarding, payments, push notifications, and deep links — running on real device farms in CI.

Black Friday load test

k6 load tests simulating 100k concurrent users across product browse, cart, and checkout flows — identifying database bottlenecks and cache misses before the sale.

Accessibility audit

Automated axe-core scans plus manual WCAG 2.1 AA audit across 200 pages — generating remediation tickets with severity ratings and code fix suggestions.

Legacy test rescue

Triage and fix a 2,000-test suite with 30% flake rate — quarantine unreliable tests, fix root causes, add retry policies, and reduce CI time from 45 to 8 minutes.

How it looks

Playwright tests that read like specs

Page Object Model, auto-waiting, and assertions that verify real user outcomes.

// Playwright E2E — checkout flow with POM
import { test, expect } from "@playwright/test";
import { CheckoutPage } from "./pages/checkout";

test("complete purchase with promo code", async ({ page }) => {
  const checkout = new CheckoutPage(page);
  await checkout.addItem("wireless-headphones");
  await checkout.applyPromo("SAVE20");

  await expect(checkout.discount).toContainText("-20%");
  await expect(checkout.total).not.toEqual(
    checkout.subtotal
  );

  await checkout.fillPayment(testCard());
  await checkout.submit();
  await expect(page).toHaveURL(/\/confirmation/);
});
FAQ

Common questions.

Playwright or Cypress — which E2E framework?

Playwright for most new projects — it supports all browsers, runs faster with parallel workers, and handles multiple tabs/iframes natively. Cypress if your team already knows it or you need its excellent component testing. We've shipped production suites with both.

How many tests do we need?

Quality over quantity. We follow the testing pyramid: many fast unit tests for business logic, integration tests for API contracts and database queries, and focused E2E tests for critical user journeys (sign up, purchase, core workflows). A well-designed 200-test suite catches more bugs than a flaky 2,000-test suite.

How do you handle flaky tests?

First, we quarantine known flaky tests so they don't block CI. Then we fix root causes: replace arbitrary waits with proper assertions, use MSW for deterministic API mocking, isolate test data with factories, and add retry logic only as a last resort. We track flake rates and treat them as bugs.

Should we test in CI or locally?

Both. Local tests for rapid feedback during development. CI tests as the quality gate before merge. We optimize CI pipelines with parallelization, sharding, and selective test execution (only run affected tests) to keep feedback loops under 10 minutes.

What about manual QA — do you do that too?

We focus on automation, but some testing benefits from human judgment: exploratory testing, UX review, accessibility audits, and edge case discovery. We help define what to automate vs. what to explore manually, and we train your QA team on automation tools.

Ready to ship with confidence?

Let's build a testing strategy that catches bugs in CI, not in production.
