• no-unknown-modifiers - Prevent the use of unknown test modifiers.
• test-ended - Ensure callback tests are explicitly ended.

Recommended config

This plugin exports a recommended config that enforces good practices.

Enable it in your package.json with the extends option:

{
	"name": "my-awesome-project",
	"eslintConfig": {
		"plugins": [
			"tape"
		],
		"extends": "plugin:tape/recommended"
	}
}

See the ESLint docs for more information about extending config files.

Note: This config will also enable the correct parser options and environment.
