Developer Self-QA
Before a build reaches us, your developers run their own pass against the ticket — catching the obvious issues early, when they’re cheapest to fix.
For CRO agencies, ecommerce teams, and Shopify, WordPress & AEM builds
Catch It Before Your Traffic Does.
QA for website builds, platform migrations, ecommerce storefronts, and A/B tests — on Shopify, WordPress, AEM, and beyond. Cross-browser, cross-device, tracking verified, and checked against the edge cases that invalidate results and cost revenue. Checked again before it ships, and again after it’s live.
- Self-QA, Final QA & Post-Launch QA
- Playwright / Cypress automation + manual UI QA
- Weekly check-ins on retainer

OUR SERVICES
Ensuring Quality at Every Stage of Development
10+ Years of Experience. One Goal: Better Results.
Our services include
What we hear
What we do
A/B Test QA
Variation renders correctly against the control, flicker, layout shift, and flash of original content, goal, event, and revenue tracking fires accurately, audience targeting and traffic allocation behave as configured, no console errors and no conflict with existing site scripts, and test does not break on repeat visits or after a session reset. Every pass runs against Brillmark’s built-in QA checklist, scripted in Cypress, so results are checked the same way every time.
What we hear
What we do
Functional QA
Forms submit, validate, and deliver; navigation, filters, search, and sorting; cart, checkout, and payment flows end to end; account creation, login, and password recovery; third-party app and integration behavior. Same rigor whether it’s a Shopify storefront, a WordPress build, an AEM site, or a custom platform.

What we do
Visual and Device QA
Chrome, Safari, Firefox, and Edge on desktop; iOS Safari and Android Chrome; tablet and common mobile breakpoints; responsive behavior between breakpoints, not just at them. Covers platform migrations and rebuilds too — Shopify, WordPress, AEM, and headless — not just A/B test variations.

What we do
Tracking and Analytics QA
GA4 events, parameters, and conversions; data layer structure and values; tag manager trigger and variable behavior; cross-domain and subdomain session continuity; consent mode behavior on accept and on deny. Plus third-party tracking and analytics tools — Adobe Analytics, Hotjar, Microsoft Clarity, and similar — checked for correct firing, accurate session/event capture, and no conflicts with the rest of the stack.
Trust Is the Deliverable.
Every long-term partnership we have started the same way: a QA report a client could actually rely on. That’s the real product — not just catching bugs, but giving your team a reason to trust the next release, and the one after that. We don’t sell long-term relationships separately. They’re what happens when QA holds up, release after release.
200+ agencies and brands — many of them years-long partnerships.

Send Your RequirementQA Doesn’t Stop at Launch.
Every release is checked at three points, not one:
Final QA
We run the full checklist — functional, visual, cross-device, and tracking — before anything ships. This is the pass your team signs off on.
Post-Launch QA
We check again once it’s live — real traffic, real devices, and the edge cases staging can’t fully simulate.

I can’t imagine any other companies out there in a similar situation where we are that couldn’t benefit from the services that Brillmark offers.
Gayla WorrellCRO at Snap Finance
Finding competent professionals to bring conversion research ideas to life and deliver results for clients without breaking their websites was challenging – until I found Brillmark. Abdullah and his team are a group of technical A-players with whom anyone serious about CRO and experimentation should work. I’ve collaborated with them on multiple projects, and they consistently prove they’re the real deal

Quality Assurance FAQs.
If yours isn’t here, send it with your requirement and we’ll answer it in the reply.
How fast is your QA turnaround?
Standard A/B test QA is returned within 24 hours of receiving the preview link. Priority QA on retainer and dedicated analyst plans is same day. Full site regression cycles are scoped individually, typically two to five days depending on the number of flows.
Do you QA tests that another team built?
Yes. Most of our QA work is on builds we did not develop. We test against your design and hypothesis rather than against the code, which means we catch cases where the build technically works but does not match what was intended.
What browsers and devices do you cover?
Chrome, Safari, Firefox, and Edge on desktop. iOS Safari and Android Chrome on mobile. Tablet and common mobile breakpoints. We test responsive behavior between breakpoints as well as at them, since that is where most layout issues actually appear.
Do you check that tracking is firing correctly?
Yes, and it is the check most often skipped. We verify GA4 events, parameters, data layer values, Tag Manager triggers, and consent mode behavior, plus any other analytics or behavioral tracking tool in your stack — Adobe Analytics, Hotjar, Microsoft Clarity, and similar. A test with correct rendering and broken tracking produces confident, wrong conclusions.
What does your QA report look like?
An annotated document with a screenshot, reproduction steps, affected browser or device, and severity for each issue. Not a pass or fail summary. Your developer should be able to reproduce and fix from the report without a follow-up call.
Can you fix the issues you find?
If we built the test, fixes are included. If another team built it, we can quote the fix separately or hand the report to your developers. Most clients on retainer have us do both, since re-verification is faster when the same team handles the fix.
Will my clients know you exist?
Not on white-label engagements. We QA under your brand, communicate only with your team, and never appear in client-facing documents or calls. Several agencies have worked with us for years without a client ever knowing.
What's the difference between your three QA options?
UI QA Only is a manual pass — cross-browser, cross-device, and interaction checks with no automation build. QA with Automation adds a maintained script suite for ongoing regression coverage. QA with Automation using Playwright/Cypress + UI combines both — automation for repeatable coverage, manual QA for what automation can’t see. Most retainer clients run the combined option; one-off releases often start with UI QA Only.
Do you QA after launch, or just before?
Both, plus a check before that. Your developers run their own self-QA first, we run a full QA pass before anything ships, and we check again after launch against real traffic and devices. Retainer clients also get a weekly check-in to review anything flagged.
Do you only QA A/B tests?
No — A/B tests are one part of it. We QA any release: Shopify and WordPress builds, AEM sites, headless migrations, feature launches, and full site rebuilds, using the same functional, visual, cross-device, and tracking checklist either way.
