The most expensive architectural decision in test automation isn’t which framework to use. It’s whether your developers can read, review, and contribute to the test code. Same-language automation is how you tear down the wall between dev and QA.<\/i><\/p>\n

We pick the test automation language from the platform under test. Java backend, Java tests. That single choice decides whether your developers can review the suite, contribute to it, and reuse what they have already built.<\/p>\n\n\n\n

There’s a popular pattern in test automation: pick a specialized testing framework, regardless of what language your production code is written in. Backend in Java? Automation in Python. Backend in Go? Automation in JavaScript. Backend in C#? Automation in whatever the QA team already knows.<\/p>\n\n\n\n

It’s convenient. It lets QA engineers work in their comfort zone. And it creates a wall between your development team and your test automation that will\u00a0cost you far more than the convenience is worth.<\/p>\n\n\n\n

On the banking platform we\u2019ve been building for years, now running 60+ microservices and 900+ API endpoints, we write the automation suite in Java because the backend is Java. We\u2019ve written about how that suite runs in parallel with development<\/a>. <\/p>\n\n\n\n

This article covers the decision that comes first: which language to write it in.<\/p>\n\n\n\n
