End-to-End Tests and Where to Use Them
Explore how end-to-end (E2E) tests verify an entire application's functionality from a user's perspective. Understand E2E test characteristics, their scope covering UI and backend systems, and how they simulate real user scenarios. Learn best practices for running E2E tests in production-like environments and their role in ensuring overall software quality within a comprehensive testing strategy.
We'll cover the following...
E2E tests are a type of software testing that focuses on verifying the functionality and behavior of an entire application from the user's perspective. Unlike unit tests and integration tests, which isolate specific components or units of code, E2E tests simulate real user interactions and test the application as a whole. Here are some key characteristics and aspects of end-to-end tests:
Scope: E2E tests cover the entire application, including the user interfaces, backend services, databases, and any external dependencies. They aim to validate that the entire system functions correctly and delivers the expected user experience.
User scenarios: E2E tests are designed to mimic real user scenarios, such as interacting with the application’s UI, submitting forms, navigating between pages, and interacting with different features. These tests follow user paths through the application.
Real user inputs: E2E tests use real user inputs and interactions, such as clicking buttons, typing into text fields, and navigating menus. They also involve simulating user actions like mouse clicks and keyboard inputs.
Realistic data: E2E tests often use realistic test data that closely resembles what real users would input or encounter during their interactions with ...
