Exsited - Subscription billing platform

Exsited is an enterprise subscription-billing and ERP platform where every release moves money - accounts, items, orders, invoices, payments and the full purchase cycle, all feeding live dashboards, so the cost of a missed defect is high. Quality ran end to end: requirements breakdown and test-case design, manual regression, API testing, and a 500+ test hybrid UI + API framework across 11 modules, architected so a single command produces a full regression and a stakeholder-ready report.

Approach

The framework drives the entire order-to-cash flow - create account, create item, place order, generate invoice, take payment - plus the mirror purchase cycle and the approvals in between, the exact paths a release is most likely to break. It pairs realism with speed by seeding preconditions through the API and driving the UI for the behaviour under test, and it catches a class of bugs screen-only testing misses: a single test reconciles the same figure across the dashboard, list, API and report, failing if any disagree. The genuinely hard workflows are covered too - two-person approvals run through a second operator context that approves or rejects independently while the first asserts the result.

It’s built to run fully parallel - collision-free data and a clean global reset keep it reliable at any worker count - with stress repeats that flush out race conditions, and every API call is timed so performance regressions show up as numbers against a baseline.

Impact

A slow, headcount-bound manual regression became a release gate the team trusts - delivering a verdict and a stakeholder-ready report on every run - and the cross-layer checks routinely surface money-movement defects that would otherwise reach production, where they cost the most.
