Introduction :

System Testing and End-to-end Testing are two different types of software testing that are used to ensure the quality and functionality of a software system.

System Testing is a type of testing that is performed on the complete system or software application to evaluate its behavior and performance. It is generally conducted after the completion of the integration testing phase and is carried out in a production-like environment. The primary objective of System Testing is to identify defects or bugs that may have been missed during the earlier phases of testing and ensure that the system meets the specified requirements.

On the other hand, End-to-end Testing is a type of testing that evaluates the entire software system, including its integration with other systems or external interfaces. It is typically performed in a simulated production environment and involves testing the software from the user’s perspective. The objective of End-to-end Testing is to ensure that the software system meets the customer’s requirements and expectations and that all components work together seamlessly.

System Testing: System Testing is carried out on the whole system in the context of either system requirement specifications or functional requirement specifications or in contest of both. System testing tests the design and behavior of the system and also the expectations of the customer. System testing: System testing is a type of testing that validates a complete and fully integrated system to verify that it meets the specified requirements. It typically includes functional testing, performance testing, security testing, and other types of testing to ensure that the system is working as expected.

End-to-end Testing: End-to-end testing is a type of software testing used to test whether the flow of a software from initial stage to final stage is behaving as expected. The purpose of end-to-end testing is to identify system dependencies and to make sure that the data integrity is maintained between various system components and systems. End-to-end testing: End-to-end testing, also known as end-to-end functional testing, is a type of testing that validates the flow of a system from start to finish. It simulates the real-world use of the system and tests it as a whole, including testing the interactions between different components.Difference between System Testing and End-to-end Testing:

System TestingEnd-to-end Testing
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 interactionsTests the system as a whole, including its integration with external systems and interfaces
Typically conducted in a controlled environment, such as a testing labTypically conducted in a simulated production environment
Focuses on evaluating the behavior and performance of the systemFocuses on evaluating the user experience and functionality of the system
Primarily tests the internal functionality of the systemTests the external functionality of the system
Performed after integration testing and before acceptance testingPerformed after system testing and before acceptance testing
Involves functional and non-functional testingInvolves functional testing and end-to-end flow testing
Testers use test cases and scenarios based on system requirementsTesters use real-world scenarios based on customer use cases and user stories
Objective is to identify and eliminate defects in the systemObjective is to ensure that the software meets customer requirements and expectations
Provides a comprehensive understanding of the system’s quality and readiness for deploymentProvides 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.

What is the difference between E2E and component testing? ›

Component tests focus on testing individual components of an application in isolation, while Cypress E2E tests test the application as a whole, including all its components and their interactions. Due to the narrower scope, Cypress component tests require less setup and are easier to write, debug, and maintain.

Is E2E testing the same as functional testing? ›

End-to-end tests are like functional testing in that they consider the user experience. However, differences between the two include the following: Scope. Functional tests validate the input and output result of each test, while E2E tests validate that each step in the process can be completed from start to finish.

What is another name for system testing? ›

System testing is also known as black-box testing because it focuses on the external parts of the system. It takes place after integration testing and before the acceptance testing. So this testing detects the issues within the integrated units of a system.

What are the three tests used in system testing? ›

A Guide To Software Testing: A Primer To Three Types of Testing
  • Automated testing involves using a tool or program that can check software functionality for a user, identifying errors in code or usability to ensure users don't have issues with software. ...
  • a) Unit Testing. ...
  • b) Smoke Testing. ...
  • c) Sanity Testing.

What is the purpose of system testing? ›

The purpose of system testing is to ensure that a system meets its specification and any non-functional requirements (such as stability and throughput) that have been agreed with its users.

What does E2E mean in software testing? ›

For development teams, software testing is an essential practice that ensures the quality and functionality of applications before they reach end users. End-to-end testing, also known as E2E testing, is an approach to testing that that simulates real user experiences to validate the complete system.

What is the difference between system testing and functional testing? ›

So the difference between System Testing and Functional Testing is that System Testing tests the entire product or section of a product while Functional Testing only tests a single feature within a section of a product.
