Understanding functional and end-to-end testing
Functional testing verifies that individual components or features of an application work as intended by comparing actual outcomes against specified requirements. It is granular, often automated, and tests inputs and expected outputs without delving into the system’s internals.
End-to-end testing simulates real user scenarios by testing the entire application flow from start to finish, encompassing multiple integrated components to ensure that they work properly together. This type of testing validates the complete system, identifying issues that may arise from interactions between different parts of the application, thus providing a more holistic assurance of software functionality and reliability.
We will start with some examples that span various common functionalities in modern .NET applications, from web services to user interfaces. As you will see, E2E tests are more complex and involve multiple features, whereas...
