However, the configuration described by the `.eslintrc` file in the `tests/` directory overrides conflicting specifications.

 By default, ESLint looks for configuration files in all parent folders up to the root directory. This can be useful if you want all of your projects to follow a certain convention, but can sometimes lead to unexpected results. To limit ESLint to a specific project, place `"root": true` inside the `.eslintrc.*` file or `eslintConfig` field of the `package.json` file or in the `.eslintrc.*` file at your project's root level. ESLint stops looking in parent folders once it finds a configuration with `"root": true`.

-You can tell ESLint to ignore specific files and directories by creating a `.eslintignore` file in your project's root directory. The `.eslintignore` file is a plain text file where each line is a glob pattern indicating which paths should be omitted from linting. For example, the following omits all JavaScript files:
