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.
