Why We Rewrote Our Python CLI in Go (and What We Gained)
The TestSmith CLI was rewritten from Python to Go to improve usability and distribution. The new version, TestSmith v2, offers a single static binary that simplifies installation and eliminates dependency issues. This transition allows for easier integration into CI environments and supports a more modular architecture for adding new language drivers.
- ▪TestSmith v1 faced challenges with Python environments in CI integration.
- ▪The rewrite to Go resulted in a single binary with no runtime dependencies.
- ▪TestSmith v2 features a cleaner command structure and a modular architecture for language support.
