How to use parent-module - 2 common examples

public constructor() {
    /**
     * Get the actual path for temp directories that are symlinks (MacOS).
     * Without the actual path, tests that use process.chdir will unexpectedly
     * return the real path instead of symlink path.
     */
    const tempDir = fs.realpathSync(os.tmpdir());
    /**
     * Get the pathname of the file that imported util.js.
     * Used to create a unique directory name for each test suite.
     */
    const parent = parentModule() || 'cosmiconfig';
    const relativeParent = path.relative(process.cwd(), parent);

    /**
     * Each temp directory will be unique to the test file.
     * This ensures that temp files/dirs won't cause side effects for other tests.
     */
    this.dir = path.resolve(tempDir, 'cosmiconfig', `${relativeParent}-dir`);

    // create directory
    makeDir.sync(this.dir);

    // re-enable once: https://github.com/typescript-eslint/typescript-eslint/issues/636
    /* eslint-disable @typescript-eslint/unbound-method */
    this.absolutePath = this.absolutePath.bind(this);
    this.createDir = this.createDir.bind(this);
    this.createFile = this.createFile.bind(this);

export function importView(pathToImport) {
  return path.join(path.dirname(parentModule()), pathToImport);
}
