Green Tests, Dead Production — How Recorded Fixtures Hide a Model Retirement, and a Freshness Gate to Catch It
A test suite that replays recorded API responses will sail straight past a model retirement. I reproduce the failure in a minimal setup and build a cassette freshness gate, with measured overhead.
Guarding Gemini API Responses in CI: Snapshot and Semantic Regression Testing
How to defend non-deterministic Gemini API responses with pytest snapshot tests plus embedding-based semantic regression detection — including CI wiring, separating flakiness from real regressions, and snapshot-update governance, all in working code.
Catching Gemini Model Deprecations in CI Before They Bite
Build a small guard that scans your codebase for hardcoded Gemini model IDs, cross-checks shutdown deadlines, and turns CI red before a model quietly disappears.
Catching Deprecated Gemini Models in CI ― A Guard for Back-to-Back Shutdown Deadlines
When shutdowns and deprecations pile up, build a CI check that mechanically finds stale Gemini model strings across your repo. Includes a deprecation registry, a scanner, and a days-remaining warn/fail tier you can copy and run.
Getting Ready for the Gemini CLI and Code Assist Personal Shutdown: A June 18 Migration Inventory
On June 18, personal access to Gemini CLI and Code Assist stops. Here is how I found every place I depended on it and moved each one to either Antigravity CLI or direct API calls, using my own setup as the example.
Stopping Gemini API Config Drift — Codifying Model IDs and Safety Settings to Catch Cross-Environment Gaps
Most of those puzzling per-app bugs come from drift in model IDs and safety settings between environments. This guide shows how to codify your Gemini config and snapshot the effective settings to detect cross-environment gaps.
Don't Let Your Gemini Prompts Silently Rot — A Practical Regression Testing Playbook with Pytest
Ever tweaked a prompt and watched production quality quietly degrade? This article walks through testing Gemini API prompts with Pytest, combining snapshot tests and LLM-as-Judge to catch regressions automatically — all from the perspective of an individual developer running things solo.
Wiring Gemini CLI into Your Shell and CI — Headless Runs and Session Resume
Move past interactive use of Gemini CLI: headless runs, JSON output, session resume, approval modes, and MCP. Includes the five ways headless runs break and a measured pro/flash comparison.
