QE from Nothing — and Then Some: Full-Cycle Quality Engineering for DealerClub’s Wholesale Auction Platform
DealerClub is the first and only reputation-based wholesale automotive auction platform, built by dealers for dealers — and recently entering an acquisition agreement with Cars Commerce, the parent company of Cars.com and Dealer Inspire. We built their entire QE practice from zero and went further, delivering proactive automation the client never asked for.
The first reputation-based wholesale auction — built by dealers, for dealers.
DealerClub is the first and only reputation-based wholesale automotive auction platform, purpose-built for automotive professionals. It enables dealers to buy and sell vehicles through a streamlined online marketplace where reputation is the currency — building a trust layer that traditional wholesale channels have never had. The platform serves automotive professionals across the United States and recently entered an acquisition agreement with Cars Commerce — the parent company of Cars.com and Dealer Inspire — a significant validation of DealerClub's position in the automotive digital commerce landscape. With a complex multi-platform product spanning web and native iOS and Android mobile apps, deeply interconnected auction flows, and no quality engineering infrastructure when the engagement began, DealerClub represented a clean-slate QE build in a fast-moving, high-stakes marketplace environment.
They had zero QA infrastructure and a complex multi-platform product in a live market. We built the full practice, then went further — delivering automation no one asked for.
At a glance.
Built, scaled, sustained.
The engagement moved through two clear phases — a foundation period focused entirely on building the documentation and testing infrastructure from scratch, followed by a scale phase that introduced structured cycles, mobile coverage, and proactive Playwright automation the client hadn't requested.
QE from scratch on a live marketplace.
When the QE team joined DealerClub, there was no quality engineering process in place. No test cases, no documentation, no defect tracking, no regression structure, and no mobile testing — for a complex, multi-platform product operating in a live wholesale automotive marketplace.
No QE Process or Documentation
No test cases, no feature matrix, no test plans, no documented approach. The team was starting from zero on a live, production product with active dealers transacting on the platform daily.
No Defect Tracking Structure
Defects were being tracked informally in Trello with no consistent format, no severity classification, and no structured workflow. Trello was later migrated to Jira as part of the QE team's process improvements.
Complex Multi-Platform Product
DealerClub operates across web and native iOS and Android mobile apps, with deeply interconnected auction flows, vehicle listing management, reputation systems, and dealer-to-dealer communication. Each platform required independent test coverage and had unique behaviours to validate.
No Automation Coverage
No automation existed anywhere in the QE process. Building automation for a platform with no existing test infrastructure required establishing the full manual foundation first — then identifying and delivering automation coverage on top.
From zero coverage to a full-cycle QE practice — and then proactive automation.
The team built DealerClub's entire QE capability from the ground up — starting with documentation and test case design, scaling into structured regression cycles and mobile coverage, and then going further than asked by delivering proactive Playwright automation that the client had no roadmap for.
Built the QE Documentation Layer
Created a complete Feature Matrix mapping every product area, then authored 300+ structured test cases covering all key flows across web and mobile. Every auction flow, vehicle listing, reputation mechanism, and communication feature was documented and test-covered before the first structured regression cycle ran.
Established Structured Testing Cycles
Introduced daily sanity testing and weekly regression cycles — giving DealerClub consistent quality checkpoints for the first time. Pre-release regression runs were structured to cover critical paths first, ensuring high-risk flows were always validated before new features went live.
Defect Management & Platform Migration
Defects were tracked initially in Trello, then fully migrated to Jira as the engagement matured. The migration introduced consistent defect formats, severity ratings, structured reproduction steps, and environment context — bringing professional defect management to a platform that had never had it.
Mobile App Testing via BrowserStack
iOS and Android native mobile testing introduced in Q3 2025, using BrowserStack for real-device coverage. Cross-platform parity was validated across core auction flows, vehicle browsing, listing management, and dealer communication to ensure consistent behaviour across all platforms.
Proactive Playwright Automation
Without being asked, the team identified the highest-value automation targets and delivered 28 end-to-end Playwright test cases. This proactive initiative gave DealerClub an automation foundation it had no roadmap for — and demonstrated what a QE partner does versus what a QA vendor does.
Continuous Feature Coverage Expansion
As DealerClub shipped new features and auction flows, the QE team absorbed them into the coverage matrix without gaps. New feature test cases were authored as features landed, ensuring the 300+ test case library remained current with the live product at all times.
The numbers.
Test Cases Created
Manual Test Executions
E2E Flows Automated
Defects Raised in Q3
What changed.
Test Cases Built from Scratch
Covering every product area — web auction flows, vehicle listings, reputation systems, dealer communication, and native mobile.
Manual Test Executions
Delivered in the Q3 engagement period across daily sanity, weekly regression, and mobile test cycles.
E2E Flows Automated
Playwright automation delivered proactively — without being requested — giving DealerClub an automation foundation it hadn't planned for.
Defects Raised in Q3
Across functional, regression, mobile, and exploratory test cycles covering the full platform.
Q2 Defect Closure Rate
Strong early-engagement closure rate, demonstrating rapid defect resolution alignment between QE and the development team.
Native Mobile Coverage
BrowserStack cross-platform parity testing introduced in Q3 — validating auction and listing flows across real iOS and Android device configurations.
The stack.
The DealerClub engagement demonstrates what it looks like to build quality engineering from nothing — and then go further than asked. The team stepped in with no process, no documentation, and no automation, and built the full QE practice from scratch. Then, without being asked, they delivered 28 Playwright end-to-end flows — giving DealerClub an automation foundation it had no roadmap for. The result: a platform that ships faster, breaks less, and has the test infrastructure to scale confidently into its next phase as part of the Cars Commerce family.
