const config = new ConfigUtil(require('./config'));

const bucket = 'gcp-utils-test';
const local_file_pathname = './test/upload_file_test.txt';
const dest_file_pathname = 'test-subfolder/upload_file_test.txt';
await upload_file(config, local_file_pathname, bucket, dest_file_pathname);

const result1 = await file_exists(config, bucket, dest_file_pathname);
// return true

const local_file_pathname2 = './test/upload_file_test2.txt';
const result2 = await download_file(config, local_file_pathname2, bucket, remote_file_pathname)
// return true

await delete_file(config, bucket, dest_file_pathname);

const result3 = await file_exists(config, bucket, dest_file_pathname);
// return false

const topic = 'gcp-utils-test';
await publish_to_topic(config, topic, {test: 'done'});
