Quality Engineering for Financial Services
Your regression cycle is the thing standing between you and a release.
It is also the thing standing between you and an audit finding.
So it grew, because both pressures push the same direction — and now it takes weeks.

Compliance-driven testing is making you less safe
Why does compliance slow down software releases?
Follow the chain.
- Testing gets organised around producing audit evidence.
- That makes it slow.
- Slow makes releases rare.
- Rare makes each release large.
Large releases fail harder, and they fail in ways that are harder to diagnose.
So the spend went up, the cycle got longer, and the actual risk — a bad change reaching production with a dozen other changes hiding it — went up too.
The firms that broke out of this didn't test less. They stopped treating evidence as a separate exercise performed after the fact.
When evidence is a by-product of testing rather than a project of its own, you can release weekly and produce a better audit trail than the firm releasing quarterly.
Traceability generated automatically from requirement to test to result beats a spreadsheet assembled from memory in week eleven — for you and for whoever reviews it.
That's the shift this page is about.
What actually breaks
Why is testing so slow in banking and financial services?
If four of those are true, adding testers will not fix it. The constraint is structural.
The core doesn't cooperate. Batch windows, overnight processing, and a mainframe or vendor platform that has no test instance you can reset. Everything queues behind it.
You can't test with real data. PII rules it out, and the synthetic data you have isn't shaped like reality — so the defects that matter only appear in production, where the data is real.
Reconciliation is where the bugs live. Individual services pass. The numbers still disagree at end of day, and nobody's tests span the boundary where they disagree.
Evidence is assembled, not generated. Someone spends the last two weeks of every cycle building a traceability pack by hand.
Decisioning logic is undertested. Lending rules and pricing models get exercised on happy paths, and the edge cases are discovered by customers or by a regulator asking about outcomes.
DORA changed what testing means
What does DORA require for software testing?
Article 26 requires every in-scope financial entity to run a digital operational resilience testing programme — risk-based, covering critical tools and applications at least annually, with weaknesses identified and closed.
Two details matter commercially. The regulation requires tests to be conducted by independent parties, internal or external — which is what an external quality partner structurally provides. And since January 2025 this has been enforceable rather than upcoming; through 2026 supervisors moved from guidance to assessment.
BaFin's January 2026 guidance confirmed that AI systems, including generative AI and LLMs, sit inside existing ICT testing and third-party risk frameworks rather than under a separate regime. If you have shipped AI features, they are in scope, and most testing programmes have not caught up.
Where we stop. We support Article 26 — scenario-based testing, resilience validation, evidence generation, and bringing AI components into the testing scope. We do not perform threat-led penetration testing under Article 27. TLPT is specialist red-team work under TIBER-EU, and you should engage a specialist for it. We'll say so on the first call.
If you're in the UK. DORA binds EU entities, so an Irish firm is directly in scope and a UK-only firm is not. UK operational resilience runs on its own track: FCA PS21/3 and PRA SS1/21, where the test is whether you can stay within impact tolerances for important business services — and that transition period closed in March 2025. If you have EU subsidiaries or branches, those entities are in DORA scope whatever the group's domicile. Work built to DORA's standard generally satisfies FCA and PRA expectations, and the reverse is not reliably true — so for a group operating on both sides, DORA is the safer bar to build to.
What we do
- Coverage where the money moves.Reconciliation and settlement paths, not just service-level happy paths. The tests that span boundaries are the ones that catch the defects that cost you.
- Test data that behaves like production without being production.Synthetic data shaped to real distributions — the edge cases, the malformed records, the accounts with twenty years of history — provisioned per run and torn down after.
- Evidence generated, not assembled.Requirement-to-test-to-result traceability produced automatically by the pipeline. The audit pack is a report you run, not a project you staff.
- Risk-based prioritisation.What gets tested first is driven by change impact and business exposure, not by whichever suite someone wrote last year.
Delivered through Test Architecture when the constraint is structural, AI-Driven Validation when it's test design, or Intelligent Quality Operations when you need the function run.

AI Test Case Generation
A WeAreQA engagement
A global financial services company.
Manual test design was consuming senior engineering time on every release. We put test scenario generation on models trained against their own requirements and defect history, with risk-based prioritisation deciding what got built first.
- 60%Faster test design
- 35%More test coverage
- 40%Less manual effort
The coverage number is the one to look at. Faster test design is easy if you write fewer tests. Doing it faster and covering more is where the design work paid off.
The business case
For the conversation with your CEO or board.
| Dimension | Today | After |
|---|---|---|
| Release frequency | Constrained by the regression cycle | Constrained by product decisions |
| Audit preparation | A project, every cycle | A report, on demand |
| Risk per release | High — large batches, coupled changes | Lower — small batches, isolated changes |
| DORA Article 26 | A gap to close | An existing programme with evidence |
The number that matters isn't the testing budget. It's what a single material incident costs — remediation, regulatory attention, and the twelve months of supervisory interest that follows. That's what this is competing against.
Where we're not the right fit
Payments and PSP work. Our financial services experience is core banking, trading and wealth, and lending. We don't claim PCI-DSS scope because we don't operate in it.
Threat-led penetration testing. Article 27 TLPT is specialist work. Not ours.
Tier-1 global banks. We're a small senior team. We'd be a subcontractor at that scale, and you'd be better served by someone who does that well.
