Coverage

How much of Blitz’s code its Go tests run: every line in apps/ and pkg/, measured with bazel coverage on Linux (where the sandbox and gVisor tests also run) on each push to main. Tools, generated code and dependencies aren’t counted. The desktop page’s TypeScript is measured separately, lines and branches, by bazel test //apps/desktop/web:coverage (Vitest’s V8 coverage, over src/ without the generated client and the development stand-ins), which fails below the thresholds in apps/desktop/web/vite.config.ts; its report is among that test’s outputs.

CI fails if the total drops below the floor in tools/coverage/floor.txt. When coverage rises, raise the floor with it, so it can only go up. Packages are listed least covered first: the top of the table is where tests are most needed.

94.1% of 52,956 lines covered (49,842 run by the tests), in 64 packages. The floor is 94.0%. Measured at commit fb5a7fd on 2026-10-19.
