How a Global Enterprise software company scaled Test Automation
and Cut QA Effort by Over 50%
with Testsigma

Customer Overview

A fast-growing, Netherland-based enterprise software company builds HR, payroll, and financial solutions used by over 1 million employees and businesses worldwide. Alongside its core web products, the company operates a high-usage mobile application that supports critical employee workflows and secure authentication flows.

With a six-week release cadence and a growing user base, maintaining application quality at scale became a high-stakes challenge. The QA team needed a way to validate every release reliably without increasing testing time, pressure, or team size.

The Challenge: Testing at Million-User Scale Under Tight Timelines

Before adopting Testsigma, the team relied heavily on manual testing and Android emulators running on virtual machines. As the mobile app expanded in functionality, this approach became increasingly difficult to sustain.

Key challenges included:

• Severe time pressure within a fixed 6-week release cycle
• Slow and unreliable test execution on emulators
• Difficulty scaling automation as app complexity grew
• Limited confidence that nightly tests would run and complete successfully
• Risk of delayed releases if regression testing couldn’t finish on time

With only one tester responsible for the mobile app, the team realized this model would either require adding headcount or accepting higher release risk neither of which was acceptable

The Solution: Scalable Mobile Automation with Testsigma

The team adopted Testsigma to automate mobile testing using real cloud devices and a low-code approach that testers could adopt quickly without deep technical complexity. What stood out during evaluation was Testsigma’s ability to scale automation reliably while remaining simple to manage even for a lean QA team.

Key capabilities deployed:

• Mobile test automation on real cloud devices
• Faster test authoring through recording and NLP-based steps
• Clear dashboards and video-based execution reports for debugging
• Jenkins-based CI/CD integration for automated nightly runs
• API-driven workflows to upload new app builds and trigger executions

Implementation & Experience

Onboarding was straightforward. Existing tests were migrated from the previous tool with minimal changes, and the team began running automated tests quickly.

Tests were scheduled to run every night, validating the full application before the next day’s work began. Each morning, the QA team could review a single dashboard to determine release readiness—removing uncertainty and last-minute firefighting.

Despite having a single tester managing the app, automation scaled smoothly across releases without increasing effort or operational overhead.

Results & Impact

With Testsigma in place, the company transformed its mobile QA process:

• Near-complete automation coverage, with every critical app function validated through automated tests
• Nightly regression runs, enabling daily go/no-go deployment decisions
• QA effort reduced by over 50%, without adding team members
• Reliable execution on real devices replaced slow emulator-based testing
• A high-severity bug was caught before release, preventing a potentially customer-impacting incident

Today, mobile releases ship with significantly higher confidence. Automation runs continuously in the background, allowing the team to focus on quality improvements rather than repetitive manual checks.
