AI Coding Assistants Create Bloated Unit Tests, Sparking Concerns

Developers are complaining that AI coding assistants like Codex generate incredibly bloated and unreadable unit tests for large codebases. When these tests fail, agents often delete and rewrite them rather than fixing them, leading to a state of "test bankruptcy" and sparking a shift towards more valuable end-to-end integration and fuzz testing.
