Difference between system, Integration and E2E test

 

System Testing

This stage of testing verifies that the software product is integrated and whole. A system test's objective is to assess if the requirements and specifications are being followed. Typically, software is just a small part of a bigger computer system. In the end, the program interfaces with hardware and/or software systems. Actually, system testing is a set of tests designed specifically to put the entire computer-based system through its paces. System testing looks for flaws in the system overall as well as in the "inter-assemblages." The behavior that is generated or seen during testing of a system or component is the actual outcome.


Integration Testing

Integration testing is a kind of testing in which systems or software modules are tested collectively and logically integrated. Several software modules written by various programmers make up a typical software project. This level of testing aims to reveal flaws in how various software modules interact with one another when they are integrated. The main goal of integration testing is to verify that these modules' data exchange complies with system specification requirements.

End-to-End Testing(E2E)

Software testing is a crucial component of software quality assurance. A high-quality product always results in a greater degree of happiness for the consumer and the innovators. Stated differently, a qualified or premium product is the outcome of comprehensive regression and defect removal at every stage.

End-to-end testing is one of the testing levels where an application flow is tested in tandem with the dependent systems, as the name suggests. This is also known as chain testing since it is carried out to guarantee seamless communication with the frontend and backend applications, such as databases or GUIs, over network channels.

In contrast to system testing, user interface testing is not relevant here; instead, the underlying data that powers the interface is tested. Typically, end-to-end testing is carried out after the product passes system testing.

What is a client and a server?

Image
A client is a piece of software or hardware for a computer that uses a server-provided service. Usually (though not usually), the server is housed on a different physical computer. A physical computer that is devoted to providing services to meet the needs of other computers is called a server. It could be a file server, database server, print server, web server, or home media server, depending on the service that is operating. One type of web client is your web browser. A protocol called HTTP is used by a client and server to interact.

What is a use case?

A use case is a description of how a user interacts with a system or product. Companies build use cases to establish success scenarios, failure scenarios, and any important variants or exceptions. Many organizations leverage use case modeling tools — such as Miro, LucidChart, and SmartDraw, for some examples — to write or visually represent a use case. Use cases are frequently employed in software development environments to simplify complicated concepts, but they can be just as important in project management for gathering requirements and defining a project’s scope.
