Code Review

This pull request adds a new script deleteFolderRecursive.js to recursively delete folders using the Google Cloud Storage Control client, along with a corresponding system test. The reviewer suggested improving the test by adding a file inside the folder before deleting it, ensuring that the recursive deletion behavior is properly verified.

[gemini-code-assist]

To properly test the recursive deletion functionality, the target folder should contain some objects (e.g., a file). If the folder is empty, the test doesn't verify that deleteFolderRecursive successfully deletes nested contents, which is its primary purpose compared to deleteFolder.

Suggested change

	it('should delete a folder recursively', async () => {
	const recursiveFolderName = uuid.v4();
	execSync(`node createFolder.js ${bucketName} ${recursiveFolderName}`);
	const output = execSync(
	`node deleteFolderRecursive.js ${bucketName} ${recursiveFolderName}`
	);
	it('should delete a folder recursively', async () => {
	const recursiveFolderName = uuid.v4();
	execSync('node createFolder.js ' + bucketName + ' ' + recursiveFolderName);
	await bucket.file(recursiveFolderName + '/test.txt').save('hello');
	const output = execSync(
	'node deleteFolderRecursive.js ' + bucketName + ' ' + recursiveFolderName
	);

Done

[nidhiii-27]

To use const [operation] = await controlClient.deleteFolderRecursive(request); you need to update the @google-cloud/storage-control library to its latest version. The current version in package.json (^0.5.0) does not include this method, which is why the test is failing.

[nidhiii-27]

Updated @google-cloud/storage-control dependency to the latest version (^0.10.0) in storage-control/package.json to resolve the test failure.
