Difference between System Testing and Endtoend Testing (original) (raw)

In system testing, whole software or application is tested at a time.

In end-to-end testing, behavioral flow of the software is tested.

Tests the system as a whole, including individual components and their interactions

Tests the system as a whole, including its integration with external systems and interfaces

Typically conducted in a controlled environment, such as a testing lab

Typically conducted in a simulated production environment

Focuses on evaluating the behavior and performance of the system

Focuses on evaluating the user experience and functionality of the system

Primarily tests the internal functionality of the system

Tests the external functionality of the system

Performed after integration testing and before acceptance testing

Performed after system testing and before acceptance testing

Involves functional and non-functional testing

Involves functional testing and end-to-end flow testing

Testers use test cases and scenarios based on system requirements

Testers use real-world scenarios based on customer use cases and user stories

Objective is to identify and eliminate defects in the system

Objective is to ensure that the software meets customer requirements and expectations

Provides a comprehensive understanding of the system's quality and readiness for deployment

Provides assurance that the system will function as expected in the production environment

System testing only tests the specific software system.

It tests the software system and the connected systems both.

The functionality of the software is tested.

Flow from end-to-end is tested.

It validates the software system as per standards and specifications.

It validated all the interfaces of the software.

Knowledge of interconnected systems is not required.

Knowledge about interconnected systems is required.

It is carried out once integration testing is performed.

It is performed after the system testing.

It is performed both manually and automated.

It is generally performed manually.

It is the super set of end-to-end testing.

It is considered as subset of the system testing.

System testing is usually a higher level of testing,

end-to-end testing is a lower level

System testing is usually done in a testing environment that closely mirrors the production environment,

end-to-end testing is typically done in an environment that mimics the real-world usage.

System testing typically has a broader scope than end-to-end testing, as it covers all aspects of the system, including its functionality, performance, security, and other features.

End-to-end testing focuses on the flow of the system, and how all components interact with each other.
