Service Overview

QA & Testing Solutions for New York Businesses

New York City runs the most demanding QA environments in the United States because Wall Street, Madison Avenue, and the city's HR-tech and accessibility-lawsuit landscape all converge here. JPMorgan, Goldman Sachs, Bridgewater Associates, Two Sigma, Citadel, and BlackRock each run massive in-house QA organisations for trading, risk, compliance, and reporting systems where a defect in production can mean a FINRA fine, an SEC enforcement action, or an unrecoverable market loss inside a sixty-second window. Codazz delivers production QA and test engineering for NYC banks, hedge funds, HR technology vendors, retailers, media platforms, and public-sector teams operating under this pressure. We build Playwright, Cypress, and Selenium end-to-end suites, Postman and REST Assured API contract tests, k6 and Gatling load harnesses, axe-core and Pa11y accessibility pipelines, BrowserStack and Sauce Labs device matrices, and trading-system specific test rigs that capture latency, correctness, and audit trails to a degree that survives a NYDFS or FINRA examiner walkthrough. Every engagement respects the regulatory layer NYC clients face today, including FINRA and SEC algorithmic trading test obligations under Rule 15c3-5 and Reg ATS, Federal Reserve SR 11-7 model risk testing, NYDFS Part 500 cyber QA, NYC Local Law 144 mandatory annual bias audits for Automated Employment Decision Tools (AEDT), and ADA Title III defensibility against the highest-volume accessibility litigation docket in the country. Our engineers work EST hours from our Edmonton and Chandigarh hubs and deliver test plans, evidence packages, and audit artefacts your internal audit, legal, and compliance teams can sign off without a second vendor engagement.

What We Build

QA & Testing Services We Offer in New York

NYC QA expectations are set by the trading floors and the plaintiffs' bar in equal measure. JPMorgan and Goldman Sachs run zero-defect-tolerance QA on order management, smart order routing, and post-trade reconciliation, where a single regression triggers a regulatory disclosure. The plaintiffs' bar files more ADA Title III digital accessibility lawsuits in the Southern and Eastern Districts of New York than in any other federal districts combined, which makes accessibility QA a board-level risk for any NYC consumer site. And as of July 5, 2023, NYC Local Law 144 requires a bias audit by an independent auditor for any AEDT used in hiring or promotion within the city. Our QA services mirror this reality. We build Playwright and Cypress end-to-end suites with deterministic data setup, REST Assured and Postman API contract tests with consumer-driven contracts where appropriate, k6 and Gatling load and soak tests for capacity and latency profiles, axe-core, Pa11y, and Lighthouse accessibility pipelines integrated into CI, BrowserStack and Sauce Labs cross-browser matrices, and bias audit harnesses for AEDT systems that produce the artefacts Local Law 144 mandates for the annual posting.

Industry Expertise

QA & Testing for New York's Key Industries

NYC QA demand concentrates in four verticals, and we have shipped in all of them. In capital markets, JPMorgan, Goldman Sachs, Bridgewater, Two Sigma, Citadel, BlackRock, and a long tail of hedge funds and broker-dealers need QA on order management, smart order routing, post-trade reconciliation, risk engines, and regulatory reporting (CAT, MiFIR equivalent, OATS legacy). We deliver test rigs that measure correctness under wire-speed latency, with audit trails that satisfy FINRA Rule 15c3-5 market access controls and SEC Reg ATS obligations. In HR technology, NYC is the global epicentre for AEDT vendors, and any tool used in hiring or promotion within city limits must clear a Local Law 144 bias audit by July 5 of each year. We build bias audit harnesses that compute the impact ratios the rule requires, document selection rates by sex, race, and intersectional categories, and produce the public-facing summary the law mandates. In media and consumer, HBO, Disney, Hearst, Condé Nast, and major NYC retailers run high-volume sites where ADA Title III lawsuits cost six figures to settle on the low end, and our axe-core, Pa11y, and manual screen reader pipelines produce evidence that has held up in actual settlement negotiations. In public sector, NYC agencies and New York State entities have growing QA obligations under NY SHIELD and the proposed NY AI Act.

Our Process

Our QA & Testing Development Process

We run discovery, test design, automation, execution, and audit support on EST hours so NYC compliance, legal, and engineering leads get synchronous standups rather than overnight async reports. Discovery opens with a regulatory scope review (FINRA, SEC, NYDFS Part 500, SR 11-7, Local Law 144, ADA Title III, COPPA, NY SHIELD) and a risk register that ranks defects by financial, regulatory, and litigation exposure rather than just by severity. Test design produces a traceability matrix linking requirements, controls, and tests, which is the artefact internal audit and external examiners actually request. Automation sprints are two weeks and reviewed against coverage targets and flake-rate budgets, with hard caps on tests that have been quarantined more than seven days. Execution runs against staging environments that mirror production data classifications, with synthetic data generation for PII-sensitive flows. Audit support includes Local Law 144 bias audit drafting in collaboration with an independent auditor, NYDFS Part 500 control evidence packaging, and ADA Title III defensibility documentation.

Technology

Technologies We Use for QA & Testing

NYC QA stacks vary widely by industry, and we adapt rather than force one toolchain. For web end-to-end we default to Playwright in TypeScript with the trace viewer and CI parallelisation, Cypress for component-heavy React apps, and Selenium 4 with Java or Python only when legacy maintenance demands it. For API testing we use Postman with Newman in CI, REST Assured for Java back ends, and Pact for consumer-driven contracts on microservices. For load we use k6 in JavaScript, Gatling in Scala, and Locust in Python depending on protocol mix and existing team familiarity. For accessibility we run axe-core inside Playwright and Cypress, Pa11y in CI for sitewide audits, Lighthouse for performance and a11y signals, and manual screen reader QA with NVDA, JAWS, and VoiceOver for ADA-defensibility work. For cross-device coverage we use BrowserStack Live and Automate or Sauce Labs Real Device Cloud. For mobile we add Appium 2 and the platform-native UI test frameworks. Test infrastructure runs on AWS us-east-1 for low-latency proximity to client environments.

FAQs

Frequently Asked Questions About QA & Testing in New York

Have a question not listed here? Reach out to our team and we will get back to you within 4 hours.

Ask a Question
How much does professional QA and test automation cost in New York City?

Local Law 144 changed what QA means for a lot of New York employers, and the budget follows which world you are operating in. Standing up Playwright or Cypress automation on a mid-size product is straightforward engineering. A trading-system or AEDT QA program at a Wall Street firm or HR-tech vendor is a compliance artefact. A Local Law 144 bias audit project (independent auditor coordination, harness development, statistical analysis, and public posting drafting) is a legal deliverable with code attached. Scope drivers include framework, CI integration, baseline coverage, and team handover. NYC rates sit above most US markets because the Wall Street and HR-tech QA talent pool commands a premium. We give fixed-fee proposals on bounded scopes and milestone-based contracts on multi-year programs.

How do you support NYC Local Law 144 AEDT bias audits?

NYC Local Law 144, effective July 5, 2023 with enforcement starting January 1 in subsequent years, requires that any Automated Employment Decision Tool used to substantially assist or replace human discretion in hiring or promotion decisions for NYC roles undergo an annual bias audit by an independent auditor. Our role is technical: we build the harness that pulls historic decision data, computes selection rates and impact ratios across sex, race and ethnicity, and intersectional categories using the formulas in the final DCWP rule, produces the data tables an independent auditor needs to issue an opinion, and drafts the public-facing summary the law requires be posted on the employer's website. We coordinate with auditors but do not act as one. We have built this harness for multiple AEDT vendors and employers and can move quickly inside the annual deadline.

Can you deliver QA for FINRA, SEC, and NYDFS-regulated trading systems?

Yes. We build test rigs that exercise order management, smart order routing, risk checks under FINRA Rule 15c3-5 market access, post-trade reconciliation, and regulatory reporting feeds (CAT, blue sheets, large trader reporting). Latency tests capture wire-speed timing distributions on the order path, correctness tests cover the FIX, OUCH, ITCH, and proprietary protocols in play, and audit-trail tests verify that every decision the system makes is reconstructable for an examiner. Under NYDFS Part 500, we produce evidence on access control, segregation of duties in deployment, and change-management testing that maps to the cybersecurity program requirements. We do not move client trading code; we test it inside their controlled environments, with our staff cleared through the firm's standard onboarding.

How do you handle ADA Title III accessibility QA in NYC's litigation environment?

The Southern and Eastern Districts of New York lead the US in ADA Title III digital accessibility filings, and a single demand letter typically costs USD $20,000 to $50,000 to settle before any remediation work, with worse outcomes if WCAG conformance is weak. Our accessibility QA program produces a current-state audit against WCAG 2.1 AA (and 2.2 AA where the client's accessibility statement commits to it), an automated pipeline using axe-core inside Playwright or Cypress with Pa11y for sitewide sweeps and Lighthouse for performance and a11y signals, and a manual screen reader QA pass using NVDA, JAWS, and VoiceOver. We produce a VPAT (Voluntary Product Accessibility Template) where procurement demands it. The evidence trail has held up in actual settlement negotiations our clients have walked through.

Do you support SR 11-7 model risk testing for NYC banks and hedge funds?

Yes. Federal Reserve SR 11-7 on model risk management requires effective challenge of models through independent testing, including conceptual soundness, ongoing monitoring, and outcomes analysis. Our QA team operates as the independent test function for client models (credit, market risk, AML, fraud, algorithmic trading) and produces challenger model results, backtesting, benchmarking, and the documentation Model Risk Management functions submit to internal audit and Federal Reserve examiners. We coordinate with internal MRM teams on scope, do not produce the validation opinion ourselves (that remains an independent function), and provide the test engineering that frees senior validators to focus on judgment rather than infrastructure.

Can you run cross-browser and cross-device QA for NYC consumer brands?

Yes. NYC consumer brands (Madison Avenue retail, Hearst and Condé Nast publishing, HBO and Disney consumer products, hospitality and restaurant groups) need cross-browser and cross-device coverage that reflects an audience using Safari on iOS 18, Chrome on Android 14 and 15, and an unusually high share of older Android devices through tourists and outer-borough demographics. We build BrowserStack Live and Automate or Sauce Labs Real Device Cloud matrices that target the device, OS, and browser distribution your analytics actually show, not a generic top-ten list. Visual regression tests use Percy or Chromatic against design system tokens. Mobile-specific flows are covered with Appium 2 and the platform-native frameworks.

How do you handle test data and PII for QA on NYC financial and HR systems?

PII handling under NY SHIELD, GLBA for financial firms, and federal employment law for HR data does not allow casual use of production data in non-production environments. Our default is synthetic data generation aligned with the production schema and distribution (using Faker, custom generators, or commercial tools like Tonic.ai or Gretel), with masking for any unavoidable production-derived test data, and a documented data flow that auditors can trace. For trading systems we generate realistic FIX message flows from market data replays. For AEDT bias audits we work with anonymised decision data that has been aggregated to the level needed for impact ratio computation. Data classification is reviewed in discovery and revisited at every milestone.

How quickly can you stand up a QA program for a NYC client?

For a mid-size SaaS or consumer product we can have Playwright or Cypress automation running in CI within four to six weeks, with meaningful coverage on the top user journeys by week eight. For a trading-system or AEDT QA program the ramp is longer (twelve to twenty weeks) because regulatory scope review, data classification, and the production-mirror staging environment all need to be in place first. For an emergency engagement (an active ADA Title III demand letter, a Local Law 144 audit window closing in weeks, a Federal Reserve exam looming) we can mobilise a dedicated pod within two weeks, working alongside the client's incumbent QA staff rather than replacing them. We have run this acceleration on real NYC client crises.
