End-to-End Testing is a software testing methodology that focuses on testing an application's flow from start to finish. It validates the complete system, including all integrated components, to simulate a real user scenario.
This type of testing ensures that all the different parts of an application work together as expected and helps uncover any potential issues that may arise from the interaction between these components. It verifies the functionality, performance, security, and reliability of the entire software system.
End-to-End Testing involves testing all layers within an application, including the user interface (UI), APIs, databases, network communication, and integrations with external systems. It may involve automating test scenarios to simulate user actions and interactions.
By conducting End-to-End Testing, companies can gain confidence in their system's functionality and mitigate risks before deploying it to production. It helps ensure that the software operates correctly under realistic conditions, providing a smooth and seamless experience for end users.
