Why clients call us
In regulated flows, working is not enough. You have to demonstrate that it works. Certification windows, migrations and regulatory audits all ask for the same artefact: a reproducible test dossier mapping requirements to executed cases to results.
We build that dossier as a deliverable in its own right. Our test sets for SWIFT MT/MX, ISO 20022, EDIFACT and X12 come from 21 years of production incidents, which is a materially different asset from a test plan written out of a specification.
What we do
- Test strategy and coverage designRequirement-to-case traceability, risk-based prioritisation, and an explicit statement of what is deliberately not covered.
- Reference test sets by protocolCurated message corpora for SWIFT MT/MX, ISO 20022, EDIFACT and X12, including the malformed and boundary cases that break mappings in production.
- Replay and pilot-mode environmentsProduction-like replay of real traffic in a pilot environment, so behaviour is observed rather than assumed before cut-over.
- Reconciliation and regression testingAutomated source-to-target comparison across the full record set, and a regression suite that survives the next release.
- Audit evidence packA structured dossier covering scope, cases, executions, deviations and sign-offs, written to be read by internal audit or a regulator, not only by the project team.
The dossier ties every requirement to an executed case and a result. Everything downstream inherits the error rate you signed off here.
Buying triggers
- A dated certification or scheme compliance window
- A migration or platform upgrade approaching cut-over
- An auditor or regulator asking for proof of control
- Recurring regressions after each release
- A first release that failed acceptance
Technical foundation
- SWIFT MT / MX and ISO 20022 test sets
- EDIFACT and X12 corpora
- Replay environments
- Automated comparison tooling
- CI-integrated regression suites
