GRAMMARLY
NATIVE iOS DEVELOPMENT
Building a better world through better writing. Cutting-edge AI empowers individuals and teams to communicate confidently and effectively - transforming how people connect, collaborate, and create.
NATIVE iOS TEST AUTOMATION
The implementation of a scalable testing architecture streamlined the regression process, significantly reducing cycle times and improving efficiency. By automating workflows and ensuring comprehensive test coverage, it accelerated release pipelines while maintaining high-quality standards. This approach enabled quicker issue detection and resolution, supporting faster, more reliable deployments and a seamless user experience.
CHALLENGE
Grammarly's rapid growth required a scalable testing architecture to support its expanding iOS platform and manage integrations across diverse devices and ecosystems. To meet this challenge, we developed a solution using XCTest and XCUITest that:
Integrated seamlessly into the post-merge process to accelerate time-to-market and ensure reliable, high-quality releases.
Extended testing across third-party apps like WhatsApp, Facebook, and Gmail, adapting to unique architectures and frequent updates for consistent performance and compatibility.
SUCCESS
More comprehensive 3rd-party testing
We implemented a Jenkins CI pipeline with integrated UI tests into Grammarly’s post-merge workflow, enabling seamless, automated testing across multiple third-party apps. Our approach delivers faster, more reliable releases while minimizing manual intervention, helping Grammarly maintain its high standards across a complex, multi-app ecosystem.
Decreased manual testing by 50%
We delivered a scalable XCUITest architecture with 70% test coverage for Grammarly, reducing manual testing efforts by 50%. This solution accelerates release cycles and ensures high reliability and consistency in testing outcomes. By optimizing automation, we provided Grammarly with a robust, time-saving framework that allows its team to focus on innovation while maintaining the highest quality standards.
Boosted stability
Configured Jenkins CI server to support Build/Run tests. Our solution reduces manual workload and ensures rapid, consistent test results, allowing Grammarly’s team to accelerate release cycles and uphold high-quality standards across every update.
Better concurrency
Integrated the SIFT open-source framework to run tests in parallel against multiple third-party integration apps on real iPhone/iPad devices.
Improved test cycle organization
Introduced the Test Orchestrator framework to manage tests and reports in CI.
