How a Leading European Online Pharmacy Reduced Testing Time by 85% and Improved Prescription Upload Success by 15%

About

A leading online pharmacy serves millions of customers across eight European countries, providing prescription fulfillment, over-the-counter medications, health consultations, and wellness products.

The company built its reputation on reliability. Prescriptions arrive within 24-48 hours, pharmacists remain available for consultations, and the platform works seamlessly whether a customer browses from their smartphone in Berlin or their tablet in Amsterdam.

But behind this seamless experience, their QA team was fighting an uphill battle.

When 200 Customers Couldn't Upload Prescriptions

Over 200 customers reported they couldn't upload their prescriptions. The images would upload, appear successful, then vanish. Pharmacists received blank files, orders were delayed, and frustrated customers threatened to switch to competitors.

After hours of debugging, the development team discovered the culprit: a specific combination of Samsung Galaxy devices running Android 11 with the Samsung Internet browser handled image compression differently than expected.

The QA team had never tested on Samsung's Android 11 because they lacked the devices.

"That incident was our wake-up call. We realized we were making decisions based on incomplete information. We were essentially flying blind, hoping our limited test coverage would catch the issues that mattered. It didn't." — Head of Quality Assurance

Finding the Right Partner for Comprehensive Test Coverage

The engineering leadership team knew they needed a different approach. They evaluated multiple cloud testing platforms against specific criteria that mattered for their business:

• Real device coverage: across European markets Actual browser–device combinations used by their customers
• Parallel execution: Eliminated sequential testing bottlenecks
• Network throttling: Simulated rural connectivity conditions
• CI/CD integration: Worked seamlessly with their Jenkins pipeline
• Compliance readiness: Supported GDPR and pharmaceutical regulations
• Geolocation testing: Enabled country-specific functionality checks
• Responsive support: Team understood healthcare-specific requirements
• Cost efficiency: Reduced spend compared to maintaining physical device labs

"We looked at four different platforms. What set LambdaTest apart was the combination of real device coverage and the platform's flexibility. We could test on actual Samsung devices, iPhones across multiple iOS versions, and even less common browsers like Samsung Internet that our customers actually used." — Head of Quality Assurance

Testing LambdaTest in a Controlled Sprint

The QA team began implementation during a controlled sprint where no major releases were planned. The team wanted to ensure LambdaTest could replicate their existing test coverage before expanding.

Initial Setup:

• Connected LambdaTest to their Jenkins CI/CD pipeline
• Migrated existing Selenium test scripts for critical user flows
• Set up automated tests for prescription upload, medication search, checkout, reorder prescriptions, and account management
• Created a test matrix covering 500+ browser-device-OS combinations across their target markets

Within the first week, they were running automated tests that previously took hours to set up manually.

"The integration was surprisingly smooth. We had our first automated test running on LambdaTest within two days. By the end of week two, we had migrated 80% of our critical test scenarios." — Lead QA Automation Engineer

Parallel Testing Reduces Execution Time by 87%

Manual testing previously consumed six days per release cycle. With LambdaTest's parallel execution, that time dropped to just four hours.

The architecture allowed 100s of tests to run simultaneously across real devices, validating prescription uploads, checkout flows, and account management in parallel rather than sequentially.

More importantly, the time savings allowed them to systematically expand test coverage based on actual customer data from their analytics.

Expanded Test Coverage Reaches 10,000+ Devices

LambdaTest's cloud infrastructure gave the QA team access to thousands of browser-device combinations without additional hardware investment.

They could now validate critical paths across configurations efficiently through parallel execution. This level of coverage seemed impossible six months earlier.

"Going from limited devices to 10,000+ browser-device combinations sounds overwhelming, but LambdaTest made it manageable. We weren't testing everything manually now. We automated the critical paths and used parallel execution to validate across configurations efficiently." — Lead QA Automation Engineer

Solving the Prescription Upload Crisis: 82% to 97% Success Rate

The original prescription upload issue stemmed from varying image compression, camera API differences, and unclear file size limits. With LambdaTest's real device testing, the team implemented adaptive compression, pre-upload validation, and device-specific camera handling.

The result: Upload success improved to 97%, and customer complaints dropped by 85%.

"LambdaTest didn't just help us find the bug. It helped us understand the problem. Testing on real devices showed us exactly how different manufacturers handled image uploads differently. That insight was invaluable." — Mobile Development Lead

Looking Forward

The team continues expanding its automated test coverage to include visual regression testing for prescription forms, API testing for backend medication databases, performance testing under varying loads, and accessibility testing for customers with disabilities.

They're exploring LambdaTest's AI capabilities for intelligent test case generation, predictive analytics for high-risk changes, automated flaky test detection, and smart test prioritization.
