Global Software Leader Achieves 100% Test Automation Coverage Across 33 Markets
How Crestech Cut Manual QA by 95% and Enabled Faster Global Releases
The Problem
A Fortune 500 enterprise with a product deployed across 33 global markets faced growing complexity in its QA process. Each quarterly release required over 300 hours of manual testing to validate functional flows, UI layouts, and localized content across multiple environments.
Testing 33 language versions - with over 1,600 UI strings per locale - led to bottlenecks, human error, and release delays. Flaky test runs, inconsistent validation between Stage and Preview environments, and lack of automation made the process unsustainable. The QA team needed a scalable, reliable solution.
The Engagement
In early 2025, the client partnered with Crestech to transform their testing approach. The objective was clear:
"Automate sanity and regression testing across all 33 locales. Eliminate manual effort. Improve test stability. Deliver results within the quarter."
A lean, two-member Crestech team collaborated closely with QA and localization leads to deliver a scalable, CI-integrated automation framework in just three months.
Our Approach
1. Scalable Automation Framework
Crestech built a modular test framework using Selenium + Java, orchestrated via TestNG, and integrated into CI/CD pipelines using Jenkins and GitHub Actions. Locale-specific data was injected through CSV and DB-driven parameterization, with all string validation mapped to the client's internal APIs and locale-specific repositories.
Designed for maintainability, the framework separated functional and locale logic - enabling rapid onboarding of new locales or test scenarios.
2. Localized Testing & String Validation
To avoid bloated test cycles, Crestech implemented a tiered locale rotation model. Locales were grouped into Tier 1-4 based on business priority, and coverage was distributed across test runs using parameterized scripts and environment variables.
A centralized string validation engine compared 1,600+ UI elements per locale against source strings retrieved via internal APIs. It included language-aware tokenization to prevent false positives and produced detailed mismatch reports for quick triage - replacing error-prone manual checks.
3. Stability & Environment Parity Enhancements
Crestech resolved inconsistencies between Stage and Preview by introducing script-based environment toggling and automated parity checks - resulting in a 90% reduction in environment-related test failures.
To improve reliability, the team added smart waits, retry logic, and parallel execution, reducing end-to-end cycle time from days to hours while eliminating flaky tests.
Impact & Results
By Q3 2025, the automation framework was fully operational, delivering significant cost, time, and quality improvements.
