About RBI

Raiffeisen Bank International (RBI) is one of Austria's leading corporate and investment banks, operating across 11 Central and Eastern European markets. With 42,600 employees serving almost 18 million customers, RBI operates strictly under European Banking Supervision. Their large team of developers competes with digital-first banks and fintech companies while maintaining the highest security standards required in the heavily regulated banking industry.

Introduction

RBI’s existing setup served its purpose early on. But growing demands for faster feedback, broader device and browser coverage, and team-specific execution called for a more scalable approach. They partnered with LambdaTest to build an infrastructure that matched its organizational structure.

As RBI's digital banking services became core business offerings serving millions of customers, LambdaTest helped ensure seamless, secure banking experiences by scaling their testing infrastructure across 40+ teams while meeting strict regulatory compliance requirements for data isolation.

As RBI's digital banking services became essential to serving millions of customers daily, LambdaTest helped ensure reliable, secure banking experiences that customers can trust across any device or browser, while enabling RBI's 40+ teams to deliver faster improvements and maintain the strict compliance standards that protect customer data.

LambdaTest built a custom enterprise architecture using sub-organizations that gave each team complete independence while sharing underlying infrastructure, including secure access to private environments and coverage across 30+ devices and multiple browsers.

Today, RBI runs thousands of tests daily across 40+ teams with secure access to real devices and browsers, all within a setup that meets stringent regulatory requirements.

Solving RBI's Core Challenges: Compliance, Team Separation, Infrastructure Modernization, and Scale

Operating across multiple European markets, RBI needed tooling that could better support its growing testing requirements while staying aligned with strict compliance standards.

To support rapid delivery across multiple teams, RBI needed a frontend testing approach that was flexible, scalable, and easy to integrate into existing pipelines. Tests written in frameworks like Selenium, Playwright, or Robot Framework had to run reliably across devices and browsers, without sacrificing speed or coverage.

Meeting those requirements resulted in four core challenges: compliance, team separation, infrastructure modernization, and scale.

1. Building Custom Team Architecture for Regulatory Compliance

RBI required a solution that would allow centralized control while ensuring strict data isolation across different testing groups. The challenge was to create a setup that could support multiple teams working independently, without cross-contamination of data, in compliance with European banking regulations.

As test automation is a key priority within RBI, we were looking for a model that fits our organizational structure and ensures that every team is able to execute their tests independently and in isolation from each other.

CTO, RBI

LambdaTest collaborated with RBI to implement an enterprise setup with sub-organizations, allowing each group to operate as an isolated entity. We implemented sub-organizations to represent individual teams.

This approach made it possible to manage licensing, usage tracking, and data isolation more effectively.

Key enterprise features like SSO and secure tunnels were also integrated, enabling seamless access to private banking environments while maintaining compliance across all layers. This enterprise setup now allows developers to test independently under a shared infrastructure, with full control and auditability.

2. Replacing Older Infrastructure with Modern Device Coverage

RBI needed comprehensive coverage across devices and browsers that their customers actually use, requiring access to modern devices and browser variants for seamless application performance.

LambdaTest's device farm provided access to 10,000+ real mobile devices and extensive browser coverage, significantly expanding testing capabilities with tools developers could use effectively.

LambdaTest's tunneling feature addressed secure connection requirements, providing the essential bridge to RBI's private banking environments while maintaining strict banking security standards.

3. Developing True Partnership Beyond Standard Vendor Support

RBI looked for a technology partner who could collaborate and show flexibility when unique requirements were presented, rather than just offering a one-size-fits-all solution.

When the RBI requested better insights into test execution, LambdaTest implemented custom dashboard features specifically based on their request, demonstrating the collaborative development approach.

The partnership provides enterprise-level support with custom development capabilities, delivering fast issue resolution combined with listening to specific problems and building solutions accordingly.

4. Scaling Operations to 8,000+ Daily Tests Right After Implementation

RBI’s Selenium Grid implementation now supports over 8,000 tests daily across their 40+ teams. The teams run tests in parallel, significantly reducing execution time and enabling faster feedback and more frequent deployments.

The test workload spans a variety of scenarios, including smoke and sanity checks, full regression suites before release, nightly builds, and interoperability testing across devices and browsers. Each team can run tests independently, without interference, while maintaining compliance with strict data isolation policies.

LambdaTest’s infrastructure supports this scale while maintaining the autonomy each team needs, enabling consistent, high-coverage testing across both web and mobile platforms.

5. Planning Future Enhancements with Accessibility Testing and Better Team Models

RBI continues expanding testing capabilities through ongoing collaboration with LambdaTest, exploring accessibility testing support to ensure banking applications work for all customers.

The collaboration includes optimizing team setup and sub-organization structure as operations expand, with LambdaTest working to enhance existing architecture and explore additional capabilities supporting evolving testing requirements.

RBI Achieved Enterprise Testing Success By Partnering with LambdaTest

Through collaborative development of custom solutions, both organizations achieved their objectives: RBI gained a scalable, compliant testing infrastructure while LambdaTest developed innovative enterprise solutions for banking requirements.

The partnership enabled RBI to scale its daily QA while maintaining regulatory compliance. The collaboration delivers complete test coverage through Selenium Grid implementation, parallel execution for faster deployment cycles, and secure access across 30+ devices and multiple browsers.

From the beginning, our collaboration with LambdaTest has been one of our biggest advantages.
