Apply two eslintrc.json files for one workspace, possible?

I have the following folder strucure:

branches
|---.vscode
	|---settings.json
|---dev-branch
	|---node_modules
	|---src
		|---lib
			|---Tools.build.js
			|---Tools.src.js
		|---index.js
	|---test
		|---dependencies
		|---html
			|---js
		|---js
		|---.eslintignore
		|---.eslintrc.json
		|---automatedTest.test.js
		|---automatedTestWithinBrowser.test.js
		|---indexForManualTesting.html
	|---.eslintignore
	|---.eslintrc.json
	|---package-lock.json
	|---package.json
	|---README.MD

.vscode/settings.json does look like this:

{
	"eslint.workingDirectories": ["./", "./branches/dev-branch", "./branches/dev-branch/test"]
}

branches/dev-branch/.eslintrc.json looks like this:

{
    "env": {
				"browser": true,
        "commonjs": true,
        "es6": false
    },
    "parserOptions": {
        "ecmaVersion": 6
    },
    "rules": {
        "indent": [
            "error",
						"tab",
						{ "SwitchCase": 1 }
				],
				"no-mixed-spaces-and-tabs":"error",
        "linebreak-style": [
            "error",
            "windows"
        ],
        "quotes": [
            "error",
            "single",
						{
							"avoidEscape": true,
							"allowTemplateLiterals": true
						}
        ],
        "semi": [
            "error",
            "always"
				],
				"no-param-reassign": [
					"error", 
					{ "props": false }
				]
    }
}

branches/dev-branch/.eslintignore looks like this:

# path/to/project/root/.eslintignore
# /node_modules/* and /bower_components/* in the project root are ignored by default

test/**/*.test.js
/**/*.build.js

branches/dev-branch/test/.eslintrc.json looks like this:

{
		"env": {
			"node": true
		},
		"globals": {
		
		},
		"parserOptions": {
			"ecmaVersion": 8
		},
    "rules": {
        "indent": [
            "error",
						"tab",
						{ "SwitchCase": 1 }
				],
				"no-mixed-spaces-and-tabs":"error",
        "linebreak-style": [
            "error",
            "windows"
				],
				"quotes": [
						"error",
						"single",
						{
							"avoidEscape": true,
							"allowTemplateLiterals": true
						}
				],
        "semi": [
            "error",
            "always"
				],
				"no-param-reassign": [
					"error", 
					{ "props": false }
				]
    }
}

branches/dev-branch/test/.eslintignore looks like this:

# path/to/project/root/.eslintignore
# /node_modules/* and /bower_components/* in the project root are ignored by default

**/*.js
!**/*.test.js

As you can see I need different configurations, because the test is written in node and the other code runs in the browser, even some code within test/ runs in the browser in particular test/js and test/html/js.

Now the problem is that branches/dev-branch/test/.eslintrc.json has no business with *.js files, because they are ignored within branches/dev-branch/test/.eslintignore. But why do branches/dev-branch/.eslintrc.jsons rules not apply for my .js files in branches/dev-branch/test/js/? It seems to me that one workspace an only respects one .eslintrc.json (the nearest one) and everything else around is is void. This is a directory-structure which is fairly common, is there any way to support it correctly? I currently use the workaround of copying branches/dev-branch/.eslintrc.json and branches/dev-branch/.eslintignore into both branches/dev-branch/test/js and branches/dev-branch/test/html (which is kind of weird and redundant) and instead of the above .vscode/settings,json I use this one:

{
	"eslint.workingDirectories": ["./", "./branches/dev-branch", "./branches/dev-branch/test", "./branches/dev-branch/test/js", "./branches/dev-branch/test/html"]
}

When I want to lint my whole folder I use the following to npm scripts and that works perfectly fine and I do not need four config files, but only as expected two config files:

"scripts": {
		"eslint": "eslint \"./**/*.js\" --ignore-path \".eslintignore\"",
		"eslintNodeTestCode": "eslint \"./test/**/*.test.js\" --config \"test/.eslintrc.json\" --ignore-path \"test/.eslintignore\"",
}

I digged into the documentation, but I could not find anything to support this IMO fairly common folder-structure, because many programs will have a test in them and therefore need a .eslintrc.json specific for nodejs and the test also may have folders in it with .js files which are executed within the browser (for example GUI-tests or in case you want to execute the test within a browser and not nodejs, for example via puppeteer) and therefore for these ones a .eslintrc.json should apply which has specific configuration for browsers.

.eslintignore files are not resolve relative to the file validated. They are resolve relative to the working directory. This is native ESLint behavior. To make this work you need to tell the ESlint extension to do a change directory by using the following syntax for the workind directory entries:

   { "directory": "./branches/dev-branch", "changeProcessCWD": true }

If this doesn’t solve your problem can you please provide me with a GitHub repository I can clone that demos the problem you are seeing.

Can you please not close a issue after 2 days… I’m busy until next month at the moment. I will respond as soon as I can.
