bun:test/padding-around-test-blocks

Require a blank line before each test and it call

fixable

Tests written right under each other, or right under setup code, are hard to tell apart when you scan a file. A blank line above each test or it call separates them.

Only the line above the call is checked, not the line below. Comments directly above the call count as part of it, so the blank line goes above them. A test that comes first in a file or in a describe callback doesn't need a blank line.

--fix inserts the blank line.

Configure#

Off by default. To turn it on:

bunfig.toml
[lint.rules]
"bun:test/padding-around-test-blocks" = "error" # or "warn"
