Optimizing #[sqlx::test] rebuild time
Summary
A Rust developer blog post analyzes why the sqlx test macro causes slow rebuilds in large suites, profiling factors like debuginfo generation, incremental session loading, and heavy macro output. It shows practical optimizations such as moving migrations to runtime, and using a shared migrator variable to reduce code bloat, with measurable rebuild-time improvements. The piece also discusses trade-offs and future improvements.
