func TempDirInMemory ¶

func TempDirInMemory(t testing.TB) string

TempDirInMemory creates a temporary directory that preferentially uses in-memory filesystems (tmpfs/ramdisk) when available. This reduces I/O overhead for git-heavy tests.

On Linux: Uses /dev/shm if available (tmpfs ramdisk) On macOS: Falls back to standard temp (ramdisks require manual setup) On Windows: Falls back to standard temp

The directory is automatically cleaned up when the test ends.
