End to End Testing focuses on testing the entire flow of the application to ensure they work as designed. E2E testing differs from Unit testing, which focuses on testing the smallest units of code, mostly functions or methods. Testing an express route helps catch any errors that might occur while in the development stage, which can boost productivity. Follow through with this tutorial to develop your first RESTful API E2E test. What is End to End Testing? End to End Testing, often called E2E testing or system testing, is a software testing technique which ensures that the application works as designed. It runs the application from start to finish, checking for any flaws in the development stage before moving to deployment. E2E testing ensures that the application meets business requirements and users’ expectations. Difference between E2E and Unit testing Unit testing is also a testing technique done in the development stage, but it involves the testing of individual components of an application. These various testing methodologies have their benefits and drawbacks. Unit testing is better at catching errors because it isolates each component compared to E2E, which tests the application as a whole. E2E, on the other hand, ensures that the application is built as intended, meeting users’ expectations. You can decide whether to pick any of the testing techniques or explore more options like Integration testing.

Passwords are very important in applications as they create a barrier between unauthorized users and a resource in the application. These passwords alone can’t prevent hackers from brute-forcing their way into your application, hence the need for Multi-Factor authentication. Multi-Factor authentication creates a two-layered barrier between an unauthorized user and resources in your web applications. To get into your application, one of the common ways is to ask the user to provide their username and password. Once this is provided, the user is required to retrieve the One Time Password (OTP) sent to their email. This strengthens the security of your various applications to a large extent. Follow this tutorial to learn how to integrate Multi-factor authentication into your applications. Prerequisites Following effectively with this tutorial requires: NodeJS 18.0+ installed.

Imagine a world without data transfer or a world where file transfer can only be done using secondary memory devices like flash drives or hard disks. This will reduce productivity, especially for transfers over a long distance. The silver lining to this is that the world has developed to where files are transferred using web/mobile/desktop applications, making drives almost obsolete. In this article, you will learn how to build and deploy a File transfer application using NextJS. Table of Content Introduction Prerequisites Setting up the frontend
