Testing

aa-sdk uses Vitest workspace projects with shared .vitest setup. CI runs affected package tests and a separate typecheck-only Vitest pass.

Rules

Rule	When to read
Vitest projects	Before changing tests or per-package Vitest config.
Anvil and Rundler	Before changing tests that depend on local chain fixtures.
Affected tests	Before choosing local verification for package changes.

Evidence

• vitest.config.ts loads .vitest and packages/* through test.projects.
• .vitest/vitest.shared.ts sets ~test, global setup, timeouts, and thread pool.
• scripts/run-affected-tests.sh uses Turborepo dry-run output to select Vitest projects.
