Client Intro
Our client is a major European retail and corporate banking institution with operations across multiple countries, serving millions of customers through branch networks, digital channels and wholesale banking. As part of its strategy to modernize its core banking platform, the bank chose the Temenos Core Banking System (Temenos T24/Transact) to power its account servicing, payments, lending and customer-data operations.
With several large change-programmes running concurrently—including regulatory changes, customer experience enhancements and digital channel launches—the bank required a robust, scalable and sustainable test automation strategy supporting the Temenos landscape. The engagement described here covered the Temenos front-office and back-office modules, interfaces (SWIFT, SEPA, PSD2), and associated digital channels.
Business Objectives
- Accelerate time-to-market for major Temenos releases, including periodic version upgrades, regulatory patches and new digital feature deployments.
- Improve test efficiency and reduce manual regression effort across the Temenos ecosystem (core banking plus interfaces plus digital channels).
- Establish a reliable “in-sprint” automation capability so that testing could keep pace with agile feature delivery rather than trailing it.
- Ensure high quality of release deliverables into the Temenos production environment—minimising defects, reducing re-work and supporting business continuity.
- Deploy a single, unified automation platform that could support not just UI testing of Temenos but also APIs, batch jobs, interface validations and data-flows—thereby reducing tool sprawl and maintenance burden.
Automation Challenges:
- Complex packaged-application behaviour: Temenos modules include embedded workflows, pop-ups, dynamically loaded grids, batch jobs and interface triggers. Traditional UI automation frameworks struggled with the dynamic controls, frames and asynchronous behaviour.
- Interfaces and eco-system integration: The Temenos rollout included SWIFT messages, SEPA/Instant payments, PSD2 APIs, legacy interface systems and data-warehouse feeds. Automating test flows end-to-end—from core to interface to downstream system—posed major complexity.
- Frequent version upgrades + regulatory patches: Temenos version upgrades (for example moving from Transact v14 to v15) and regulatory patches required regression coverage across a huge feature set. Conventional automation frameworks could not sustain the elevated maintenance load.
- Tight release windows: Because the bank adopted agile/delivery-train models for new banking features (digital onboarding, mobile payments, loan workflows) the testing cycle had to compress from days/weeks to hours. Manual regression was a bottleneck.
- Data-state and environment management: Temenos deployments require large volumes of test data (customer accounts, payment flows, exceptions, settlements). Setting up the right data-state was time-consuming. Additionally, automating interfaces required clean state, message queues and backend verification.
- Skills & reusability constraints: The bank’s test teams included business testers, functional test analysts and a small automation team versed in legacy tools. Transitioning them to handle Temenos automation, maintaining reusable assets across modules, and building a sustainable automation architecture was non-trivial.
The shift from fragmented tools and brittle scripts to ACCELQ’s unified automation platform has been transformative for our Temenos rollout. We now run dependable nightly suites, support in-sprint automation, and release major features with the speed and assurance our business demands.

Benefits
Reduced regression-cycle time by ~75 %:
- Before ACCELQ deployment, regression for a Temenos release averaged ~4 days of manual and semi-automated effort. With ACCELQ’s codeless automation and reuse model, the regression cycle dropped to under 1 day.
Re-use of ~80 % of automation assets across Temenos modules:
- ACCELQ’s modular business-process modelling enabled automation assets in one module (e.g., account opening) to be reused for another (e.g., loan origination), reducing incremental scripting for new features by ~80 %.
Maintenance effort cut by ~60 %:
- Because Temenos upgrades often trigger UI changes, many scripts would break. ACCELQ’s AI-driven object-handling and model-based design meant that maintenance required far fewer manual interventions—in one instance the bank reported the maintenance cost per test case fell to one-third of previous levels.
Full-stack coverage (UI + API + batch + interface) from one platform:
- ACCELQ supported Temenos UI, REST/SOAP interface automation, database validations and batch-job triggers. The bank consolidated from three separate tools to one unified platform—reducing license, training and tool-integration cost by ~25 %.
In-sprint automation enabled:
- Business testers and feature teams could trigger automation during the sprint rather than waiting for end-of-sprint regression. As a result, defect-leakage into production dropped by ~40 % and time to remediate fell by ~50 %.
Improved release confidence and business-continuity:
- With regular unattended execution of nightly automation suites and detailed business-process dashboards, the QA leadership had actionable visibility into risk prior to go-live. One release went live with zero Severity-1 defects in production, a historic first for the bank.
Quantifiable ROI:
- Manual effort avoided: ~1,200 tester-days per year.
- Automation-development and maintenance cost: reduced, achieving pay-back of the ACCELQ investment within ~10 months.
- Cost of Quality improved – the bank estimated ~45 % reduction in defect-remediation cost post go-live.
- Release-frequency improved from quarterly to bi-monthly for large Temenos module releases—enabling faster business value realisation.
