Steps to reproduce

const create = require('@vue/cli-test-utils/createTestProject')
const path = require('path')

test('should work', async () => {
  const project = await create('test-no-git', {
    plugins: {
      '@vue/cli-plugin-babel': {}
    }
  },
  path.resolve(__dirname, '../../test'),
  false // initGit
) 
})

What is expected?

create a project without git

What is actually happening?

git init

It seems vue create test_project --git false is deprecated.

vue-cli/packages/@vue/cli-test-utils/createTestProject.js

Lines 45 to 53 in ebdcac3

	const args = [
	'create',
	name,
	'--force',
	'--inlinePreset',
	JSON.stringify(preset),
	'--git',
	initGit ? 'init' : 'false'
	]

so, the code maybe should be like this (created a pull request)

  const args = [
    'create',
    name,
    '--force',
    '--inlinePreset',
    JSON.stringify(preset),
    initGit ? '--git' : '--no-git'
  ]
