What I Learned Building a Mobile Test Framework (and Arguing with Myself the Whole Time)

Five months ago, I started building a mobile end-to-end native automation framework at Jump. It sounded ambitious. It was ambitious. And if I’m honest, the first real resistance I encountered wasn’t from the codebase—or even my teammates—but from myself.

“Can I really do this?”

“Is it even possible to test this stuff cleanly?”

“What if this breaks everything and I have to fake my own disappearance?”

These were just a few of the many encouraging thoughts that accompanied me in the early days.

Quality at Speed (Isn’t Just a Buzzphrase)

But here’s what I’ve learned: building with quality and speed isn’t just a nice-sounding ideal. It’s possible—and it’s crucial—if you design for it. I’ve come to understand that quality isn’t a gate at the end. It’s something you bake in from the beginning, quietly, deliberately, and persistently.

The framework I’ve been building isn’t flashy. It doesn’t shout. It just runs—I mean, it runs right now, and fingers crossed, tomorrow too. And it gives us the kind of confidence that lets you ship without breaking into a cold sweat.

Working with People (and the Occasional Bad Attitude)

This project has also taught me how to navigate working with folks who have very different priorities—or, let’s be real, different moods. Some days I was the team optimist, and other days I was discussing test reliability with someone who thought QA was short for “Quick Annoyance.”

But the truth is, every team has its tensions. What matters is whether you can move through them and still make progress. I’ve learned to advocate for quality without derailing momentum, to keep things lightweight without being sloppy, and to invest in relationships while still delivering results.

Contributing Beyond the Code

What surprised me most was how much this kind of work influences team culture. Good tests don’t just find bugs—they build trust. They create space for faster experimentation, cleaner code, and less hand-wringing before a release. And when people start to believe in the system you’ve built, they start to believe in the process too.

This framework hasn’t just helped us catch issues earlier. It’s helped engineers feel more confident, product managers sleep better, and it’s added a layer of stability that supports the whole team.

TL;DR

• A mobile end-to-end native test framework was designed and implemented from scratch
• Quality and speed were prioritized together—baked into the development process, not bolted on
• The framework now supports confident, low-stress releases
• It was built in a collaborative environment with real-world constraints, shifting priorities, and occasional resistance
• Along the way, it helped shape a stronger engineering culture grounded in trust, clarity, and care
