Coverage testing on .vue files

Hi,

I am currently using meteortesting:mocha, lmieulet:meteor-coverage and @vue/test-util to do unit test on my apps.
It is OK. I am to run unit tests on my components but on the coverage report, I only see .js files and not .vue files.

Command I use:

MONGO_URL='' BABEL_ENV=COVERAGE TEST_BROWSER_DRIVER=puppeteer COVERAGE=1 COVERAGE_OUT_LCOVONLY=1 COVERAGE_OUT_HTML=1 COVERAGE_VERBOSE=1 COVERAGE_APP_FOLDER=$PWD/ meteor test  --once  --driver-package meteortesting:mocha

Do I miss something?

On package.json file, I have the following entry:

"babel": {
		"env": {
			"COVERAGE": {
				"plugins": [
					"istanbul",
					{
						"include": [
							"imports/**/*.{js,vue}"
						],
						"extension": [
							".js",
							".vue"
						]
					}
				]
			}
		}
	},
