This is actually working correctly already. Uncovered files are resolved from the project root:

vitest/packages/coverage-v8/src/provider.ts

Lines 373 to 386 in 8ac7011

	const allFiles = await this.testExclude.glob(this.ctx.config.root)
	let includedFiles = allFiles.map(file =>
	resolve(this.ctx.config.root, file),
	)
	if (this.ctx.config.changed) {
	includedFiles = (this.ctx.config.related || []).filter(file =>
	includedFiles.includes(file),
	)
	}
	const uncoveredFiles = includedFiles
	.map(file => pathToFileURL(file))
	.filter(file => !testedFiles.includes(file.pathname))
