Client
A multinational professional services firm and one of the Big Four accounting organizations, the client offers assurance, tax, transaction, and advisory services globally. To improve testing consistency, reduce cycle times, and support enterprise-wide digital transformation, the client partnered with Hexaware to establish a centralized Testing Center of Excellence—a key pillar in its quality engineering strategy.
Challenge
Fragmented Testing, Rising Costs, and Slow Releases
The client managed over 45 business-critical applications across six portfolios, with technologies ranging from Java and .NET to Azure, ServiceNow, Informatica, Hive, and mobile platforms. Testing operations were siloed, leading to inconsistent practices and mounting costs.
Key pain points included:
- Diverse technology stacks and integration complexities across enterprise applications
- Limited reuse and visibility due to fragmented testing efforts
- Low automation levels increasing the cost and time of quality assurance cycles
- Gaps in test data availability, impacting test coverage
- A growing business imperative to implement continuous testing and CI/CD integration
- Difficulty in meeting quality standards for both functional and non-functional requirements (performance, mobile, data, APIs)
To meet the demands of faster, high-quality releases, the client needed a unified and scalable test automation solution that could enable full-lifecycle quality engineering.
Solution
A Strategic Testing Center of Excellence
Hexaware took full ownership of the transformation by establishing a Testing Center of Excellence with a strong governance model, SLA framework, and KPI tracking.
Key actions included:
- Onboarding of domain-specific and cross-functional testers, including ServiceNow-certified professionals
- Upskilling 30% of manual testers to SDETs, expanding in-house automation capabilities
- Adopting an automation-first strategy across the testing lifecycle
- Implementing a comprehensive test automation framework:
- Automated Testing Framework (ATF) for ServiceNow
- SoapUI for API testing
- SeeTest (Experitest) for automated mobile testing on iOS and Android
- Integrating continuous testing into the Jenkins CI/CD pipeline
- Automating synthetic test data generation with GenRocket for production-like scenarios
- Deploying , Hexaware’s big data testing platform, to validate high-volume data and transformation logic
This unified testing ecosystem enabled cross-portfolio reuse, full-stack coverage, and seamless integration with the client’s DevOps pipeline.
Benefits
Faster Testing. Better Coverage. Zero Critical Defects.
The engagement delivered significant results, including:
- 70% reduction in test cycle time through test automation and continuous integration
- No P1/P2 defects in production—thanks to rigorous, early-stage quality checks
- Single-pane visibility across applications with defined quality gates, SLA adherence, and productivity metrics
- Scalable test automation assets enabling consistency and reuse across portfolios
- Lower cost of quality, accelerated time-to-market, and higher release confidence
By embedding quality across the lifecycle, Hexaware helped the client move from reactive testing to proactive assurance.
Summary
Hexaware’s end-to-end test automation solution, driven by a centralized Testing Center of Excellence, enabled a global professional services firm to cut test cycles by 70%, prevent critical production defects, and drive testing maturity across 45+ applications. With an automation-first strategy and a unified test automation framework, the client transformed testing into a strategic enabler of speed, quality, and business resilience.
