The rules will only activate in test files.

• max-asserts - Limit the number of assertions in a test.
• no-cb-test - Ensure no test.cb() is used.
• no-identical-title - Ensure no tests have the same title.
• no-ignored-test-files - Ensure no tests are written in ignored files.
• no-invalid-end - Ensure t.end() is only called inside test.cb().
• no-only-test - Ensure no test.only() are present.
• no-skip-assert - Ensure no assertions are skipped.
• no-skip-test - Ensure no tests are skipped.
• no-statement-after-end - Ensure t.end() is the last statement executed.
• no-todo-test - Ensure no test.todo() is used.
• no-unknown-modifiers - Prevent the use of unknown test modifiers.
• prefer-power-assert - Allow only use of the asserts that have no power-assert alternative.
• test-ended - Ensure callback tests are explicitly ended.
• test-title - Ensure tests have a title.
• use-t - Ensure test functions use t as their parameter.
• use-test - Ensure that AVA is imported with test as the variable name.

This plugin exports a recommended configuration that enforces good practices.

To enable this configuration use the extends property in your package.json.

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

See ESLint documentation for more information about extending configuration files.

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