Validate Financial Data Before It Moves
Tristha validates source-to-target accuracy, transformation logic, reconciliation integrity and load reliability across ETL and ELT pipelines — for banks, insurers and payment providers, and for every enterprise whose reports and decisions run on moving data.
Source-to-target mismatches
corrupt customer records, transaction data, account information and downstream business outputs.
Transformation rule errors
change how data is classified, calculated, formatted, aggregated or reported.
Missing, duplicate or incomplete records
weaken reconciliation, reporting confidence and operational processing.
Schema and field-level drift
source structure, data type or mapping changes break pipelines across releases.
Batch and incremental load failures
delay reporting, reconciliation, statements, settlements, renewals and claims.
Pipeline regression
a change to one job quietly breaks another; without automated regression, defects surface weeks later.
Late data defects
rework near go-live, delayed releases and costly downstream corrections.

ETL Testing Challenges in Enterprise Environments
Our Offerings
Bridging Old and New
We test across legacy and modern systems together, validating integration points so upgrades and patches don't disrupt live operations.
Audit-Ready Compliance
Test coverage mapped to compliance requirements, with audit-ready documentation proving changes introduce zero regulatory gaps.
Precision on Business Logic
Rigorous testing of calculations, account rules, and workflows — because even small changes can break customer accounts and financial reporting.
Accuracy at Every Step
End-to-end validation of balances, calculations, settlements, and reports — catching discrepancies before they hit production.
Built for Scale
Testing under real transaction loads to confirm performance, scalability, and responsiveness hold up at scale.
Smart, Secure Test Data
Realistic, production-like test data — masked and anonymized to protect customer information without compromising coverage.
Build reusable regression suites
that protect critical BFSI functionality across releases, patches, upgrades and enhancements.
Prioritize high-risk test coverage
across transaction paths, regulatory workflows, integration points and revenue-impacting functions.
Execute regression cycles
to confirm that existing features continue to perform after application changes.
Optimize test packs
by removing redundancy, improving coverage and focusing effort on business-critical scenarios.
Identify automation-ready regression scenarios
for faster, repeatable and scalable release validation.
Deliver release-readiness insights
through test progress, defect trends, coverage status and go/no-go support.
ETL Testing Services
Source-to-target validation
across core systems, payments, insurance, CRM, warehouse, lake and reporting layers.
Transformation logic verification
business rules, calculations, classifications, aggregations, formatting and field-level mappings.
Reconciliation testing
missing records, duplicates, mismatched values and incomplete loads, with full-population comparison.
Schema and metadata testing
table structures, columns, data types, formats and mapping rules, including schema-evolution checks.
Batch, incremental and CDC load validation
scheduled jobs, dependencies, exception handling, reload scenarios and processing windows.
Pipeline regression testing in CI/CD
reusable automated suites that re-validate pipelines on every release.
Performance and SLA validation
load-window timing, volume handling and processing throughput.
Report and consumption-layer validation
verify that dashboards, regulatory reports and extracts reflect validated data.
Validate business functionality
across onboarding, payments, cards, lending, deposits, insurance, servicing, reporting and back-office operations.
Design scenario-led test cases
increases as banks, insurers and financial platforms respond to regulatory, product and digital transformation demands
Test end-to-end workflows
across screens, APIs, integrations, data flows, downstream systems and customer-facing channels.
Verify business rules and calculations
for transaction accuracy, eligibility checks, fee logic, interest computation, claims rules and process outcomes.
Execute positive and negative test scenarios
to confirm expected behaviour across standard, alternate and exception conditions.
Report functional defects clearly
with severity, impact, reproduction steps and business context for faster resolution.
Why Tristha
Financial domain depth
we validate ETL workflows through the lens of financial processes, not just technical data movement.
Techno-functional QA
source-to-target validation connected to business rules, reporting needs and operational dependencies.
TraviS-powered automation
automated reconciliation, field-level comparison, schema checks and duplicate detection, integrated with CI/CD.
Mapping-led method
testing anchored to documented source definitions, transformation rules and target expectations.
Reusable validation assets
repeatable suites across data flows, migration cycles and release programmes.
Release-readiness focus
clear, evidence-based visibility into data gaps, defect impact and downstream readiness before go-live.
Find data gaps before they move into reports, records and decisions.
Client Outcomes,
in Their Own Words
We sincerely appreciate the expertise and dedication demonstrated by Tristha & Finonyx in supporting our Performance Engineering and Test Automation efforts during the Flexcube 14.7 upgrade project. Their proactive approach, technical proficiency, and untiring commitment were instrumental in the success of this upgrade.
A key highlight was their exceptional performance engineering efforts, which covered all critical transactions across Flexcube Modules, OBBRN, APIs, ATMs, Mobile Applications and Other Application Interfaces. The team effectively simulated real-world production scenarios, generating various transaction loads within SLA-defined timeframes. This rigorous testing helped validate the application’s performance under actual operating conditions.
Additionally, TerrA’s capability to automate testing across various Flexcube 14.7 modules, including Web and APIs ensured comprehensive end-to-end test coverage for the base Flexcube modules. We also greatly appreciate the extensive training and dedicated support provided to the QA & Testing team and various Business Units/Teams on TerrA.
We are truly grateful for their contributions on this great Project Everest and looking forward to future collaborations.

We appreciate the support provided by Tristha & Ifinity in our Test Automation and Performance Engineering efforts during the Temenos T24 upgrade project. Their structured approach and technical expertise contributed to the overall execution of the upgrade. One key aspect was the ability of their automation platform ‘TerrA’ to support testing across multiple platforms, including web, mobile, APIs, databases, and file validations, enhancing test coverage. Additionally, their performance engineering efforts included testing critical transactions across T24, ATMs, and mobile applications. By simulating real-world transaction loads within SLA-defined parameters, they contributed to the validation of the application’s performance under operational conditions. We acknowledge their contributions to the project and appreciate the collaboration.

We had been constrained for months by our dependency on the switch and a rigid simulator that forced all test traffic through the switch layer. Working with Tristha’s SiPay simulator, we were able to bypass switch entirely and test directly against the core by building the required AS 2805 flows in SiPay, with no new code and no configuration changes to our environment, and this has now unlocked faster regression and far better reuse of our existing script automation assets.
