Lack of formal QA processes

QA practices were not standardized across teams, with no consistent regression strategy or scalable automation in place, reducing confidence in frequent releases.

Insufficient test coverage

With only about 300 tests, coverage was fragmented and incomplete, leaving critical user flows and cross-platform scenarios exposed to regressions.

Phase 1

Establishing QA strategy and embedding teams

Zoolatech introduced a comprehensive QA strategy across both mobile and web platforms. Seven cross-functional teams were staffed with paired iOS, Android, and Manual QA engineers working side by side to increase collaboration, ensure accurate test coverage, strengthen product understanding, and maximize delivery efficiency.

Phase 2

Introducing processes and scalable best practices

The team built and continuously refined dedicated testing backlogs aligned to business goals. Automation frameworks were architected for scalability and low maintenance, supported by clear and readable test cases that simplified onboarding. Network mocking techniques were adopted to achieve the 98% test stability, and CI/CD pipelines were configured to run thousands of automated tests in under 15 minutes.

Phase 3

Implementing mobile and web testing frameworks

Zoolatech implemented platform-specific frameworks to ensure consistency and depth of coverage: XCUITest for iOS, Espresso and Robolectric for Android, and Playwright/Cypress for web testing.

Phase 4

Developing custom tools and libraries

To enhance reliability and extend platform capabilities, the team introduced custom tooling. On iOS, this included StubProxy for network stubbing and Custom Mutators to expand XCTest functionality. On Android, custom utilities improved execution stability and strengthened code coverage.

Leveraging Salesforce out-of-the-box features when possible.
Prototyping and deploying alternatives when features were missing or costly.
Setting up CI/CD for faster, automated deployments.
Applying Agile best practices with short feedback loops.
Ensuring continuous QA and system monitoring.

Phase 5

Optimizing CI/CD and test execution

Using GitLab CI/CD, the team built optimized pipelines designed for speed and resilience. Test sharding enabled parallel execution across devices, drastically reducing total test runtime and supporting fast development cycles.

Phase 6

Enhancing observability and reporting

Allure reporting was integrated to provide real-time visibility into test health, performance metrics, and overall system behavior, enabling fast diagnostics and continuous quality monitoring.

Phase 7

Ensuring long-term enablement and continuous improvement

Zoolatech provided ongoing improvements to test suites, regularly refining strategies to match evolving business needs. The team also invested heavily in knowledge sharing, training, and internal enablement to strengthen the client’s long-term QA capabilities.

Scalable automation is the foundation of modern quality. We built a QA system designed to support fast releases without sacrificing stability or customer experience.

Mobile and web QA strategy

Zoolatech introduced a full QA strategy across mobile and web, embedding manual and automated testing into seven cross-functional teams. Paired iOS, Android, and Manual QA engineers worked together to strengthen collaboration, coverage, and delivery efficiency.

Processes, architecture, and frameworks

The team maintained focused testing backlogs and built scalable automation frameworks supported by readable test cases. The network mocking achieved the 98% test stability, and CI/CD pipelines executed thousands of tests in under 15 minutes using XCUITest, Espresso, Robolectric, Playwright, and Cypress.

Custom tools and execution enhancements

The implemented custom iOS tools (StubProxy, Mutators) and Android utilities enhanced test reliability and coverage. GitLab CI/CD and test sharding improved speed and stability, while Allure reporting provided real-time observability.

Analytics automation and AI localization QA

Custom analytics interceptors detected malformed or misfired events and staging-to-production discrepancies, preventing a major revenue attribution loss and ensuring zero tracking gaps at launch. An AI-enhanced localization framework validated UI layout, translations, and visual accuracy across markets, prevented a critical production issue, and delivered a 95% faster localization QA turnaround with zero critical defects.

QA process expansion and test coverage growth

Zoolatech expanded QA processes for mobile and web teams, developed and maintained more than 3,000 tests during regression cycles, and achieved 75% automation coverage across iOS and Android.

Option	Risk	Mitigation
Unstable or incomplete analytics tracking	Misfired events, malformed payloads, or staging–production discrepancies could lead to inaccurate reporting and revenue attribution loss.	Custom interceptors were integrated to automatically detect tracking issues, with automated analytics validation embedded into the CI/CD pipeline.
Variability in localization across markets	Inconsistent translations or layout regressions could degrade user experience and cause revenue-impacting UI issues.	An AI-powered localization validation framework flagged visual and semantic defects early, preventing critical production issues.
Instability in automated test execution	Large-scale mobile test suites are vulnerable to flaky tests and unreliable execution environments.	The network mocking, custom tooling, and parallel execution strategies improved test stability to 98% and ensured consistent runtime performance.

The QA transformation delivered measurable improvements across test coverage, release velocity, analytics accuracy, and localization quality.

Expanded test coverage and QA maturity

Zoolatech grew the test suite to more than 3,000 automated and manual tests, achieving 75% automation coverage across iOS and Android. The streamlined approach reduced manual regression testing from 48 hours to 8 and cut full-suite execution time from 2 hours to 17 minutes through parallelization.

Analytics reliability and monitoring accuracy

Custom analytics interceptors identified critical event tracking issues before release, preventing a complete revenue attribution loss. Automated analytics checks were embedded into the CI/CD pipeline, ensuring every build launched with zero tracking gaps and restoring trust in measurement accuracy.

AI-driven localization quality

The AI-powered localization framework accelerated validation by 95%, detected translation and layout defects in real time, and eliminated critical localization bugs in production. It also prevented a high-impact German UI issue that would have caused significant revenue loss.

Sustainable quality at scale

The unified QA ecosystem enabled the client to maintain consistent quality across teams, platforms, and release cycles, improving confidence in every deployment.

Faster innovation across mobile and web

With automation embedded into daily workflows, engineering teams can now ship updates more quickly while reducing manual overhead and avoiding costly production issues.
