Wrote about using #googlejules to migrate an #RStats test suite to #testthat

From RUnit to testthat with Coding Agent Support | Mirai Solutions GmbH
We present an interesting case study: we migrated the test suite of our R package ๐ซ๐๐๐ผ๐ป๐ป๐ฒ๐ฐ๐ from ๐ฅ๐จ๐ป๐ถ๐ to ๐๐ฒ๐๐๐๐ต๐ฎ๐ using ๐๐-๐ฝ๐ผ๐๐ฒ๐ฟ๐ฒ๐ฑ ๐ฐ๐ผ๐ฑ๐ถ๐ป๐ด ๐ฎ๐ด๐ฒ๐ป๐๐s. We used ๐๐ผ๐ผ๐ด๐น๐ฒ ๐๐๐น๐ฒ๐, an asynchronous coding agent, to handle the repetitive, multi-file refactoring work. The process wasn't just about automation, it required careful context preparation, environment setup, and iterative prompt engineering. Key ๐๐ฎ๐ธ๐ฒ๐ฎ๐๐ฎ๐๐: โข AI agents excel at tedious, semantics-aware tasks (like fixing ๐ฆ๐น๐ฑ๐ฆ๐ค๐ต_๐ฆ๐ฒ๐ถ๐ข๐ญ argument order across dozens of files) โข Managed VM environments reduce risks while maintaining utility โข Combining different AI tools (Jules + Aider) provided robust validation through "third-party" code review This results in a faithfully migrated test suite with equivalent coverage and behavior, achieved faster and with more confidence. Read about our process, challenges, and solutions in our news post. https://lnkd.in/d-QUGDJ4 #rstats #SoftwareDevelopment #AIEngineering #TestAutomation #OpenSource
