Turn microservice complexity into a competitive edge with a CI/CD pipeline

eCommerce moves at the speed of deployment, and ‘it works on my machine’ is the ultimate technical debt that keeps tech leaders staring at broken builds instead of growth metrics.

When you’re managing a premier gifting platform in the EU, every click represents a personal connection. Behind the scenes, a sophisticated microservice architecture handles everything from inventory to secure payments.

It’s elegant and scalable, but when it comes to testing, it can be notoriously chaotic.

This is the story of how our team stepped in as a strategic partner to transform a testing bottleneck into a competitive advantage by leveraging test automation for microservices.

Challenge: when distributed systems create centralized headaches

Our client faced a classic ‘‘success problem.’’ As their platform grew, their microservice architecture became a tangled web, making comprehensive function testing nearly impossible.

In a microservice environment, you aren't just testing code; you're testing the invisible handshakes between services. Without automation, you aren't moving fast. You. Are. Just. Guessing.

Traditional manual testing couldn’t keep up with the pace of their development. Every time a developer pushed code to one service, the fear of “the ripple effect” where a small change breaks a seemingly unrelated feature, loomed large.

Our strategy: engineering predictability into chaos

Our approach went beyond the mindless cycle of writing scripts, rinse and repeat. We integrated a specialized team of 8 experts to overhaul the platform's reliability DNA.

99.9%
system uptime
100%
critical path coverage
75%
reduction in deployment time

Our goal wasn’t just to “find bugs,” but to build an invisible guardrail that allowed the client to innovate without fear.

1. Mocking the noise

To solve the “ripple effect,” we implemented a strategy focused on mock tests and mock data. By simulating the behavior of external services, we allowed developers to test individual microservices in total isolation. This eliminated the noise and let us pinpoint errors with surgical precision before they ever touched the live environment.

2. Utilizing the power duo: Cypress & Playwright

We chose a modern tech stack centered on Cypress and Playwright, powered by TypeScript and JavaScript. These tools allow for blazing-fast execution and deep integration into the browser. We didn’t just test if a button worked; we tested the entire user journey through the lens of the machine.

3. Continuous confidence (CI/CD)

We established a workflow where every single developer’s code push triggered an automatic “interrogation” of the system. Testing moved from being a “final phase” to an “instant feedback loop.”

The outcome: 100% coverage, 0% guesswork

By shifting to a ''test automation for microservices'' mindset, the results were transformative; not just for the code, but for the business.

Scaling a tech company isn’t just about hiring more “coders.” It’s about building systems that scale with you. True tech transformation happens when you stop being a vendor and start being a partner who understands that reliability is the ultimate feature.

Ship features, not bugs — at 7x% higher velocity
