The goal of this test is to create a working code against 4 simple fake APIs. We are simulating two requests coming from users (two arrays of strings).
You have to do the following for each string:
- Translate the source language using
translation.translate()(Or fetch the same data from cache if available / store in cache if not). - Get a binary (a fake MP3) for a TTS speech for the translated text using
speech.speak()(Or fetch an existing URL from cache if available / store in cache if not). - Store the binary data into storage and get a URL for said data using
storage.pipe(). - Respond to the user by calling
respond()for each request with the data in the following format:
const response = {
translations: [], // Add all the translated strings to this array in the same order as they came in
speech: [] // Add all the speech URLs to this array in the same order as the translations
}Each fake API respons with a Promise and simulates the real world by taking some time to respond.
cache.getItem("someKeyHere"); // Returns a promise that resolves to a string if found or undefined if not.
cache.setItem("someKeyHere", "someDataHere"); // Returns a promise that resolves after the cache has been stored.translation.translate("English Source Text"); // Returns a promise that resolves to a string containing the translation as a string.speech.speak("Texto fuente en español"); // Returns a promise that resolves to a readable stream that will stream binary data (async).storage.pipe(stream); // Returns a promise that resolves to a fake URL once the stream has ended. A unique URL for each source text will be provided.
