What is End-to-End (E2E) Testing? And Its Five Benefits

Determining the efficiency, consistency, and performance of a software application is important for a better receptivity in the marketplace. Software applications these days are integrated into multiple systems. It is a process by which your application seamlessly communicates with other softwares to exchange data and work together. Application integration helps to merge and optimize data and workflow between two different software applications.

Application integration is a complex process. If a particular software application fails to perform efficiently outside an enterprise environment, the performance of the application in which it is integrated will also be hampered. Automated testing React Native is a Javascript-based framework that checks the performance, stability, and integration of hybrid applications across different operating systems.

Mobile end to end testing for native mobile devices helps check the mobile application’s performance in an integrated environment. This helps to ensure that the app will have a stable performance and can be maintained easily.

End-to-end testing determines the stability and optimal level of performance of the application’s workflow from beginning to end. It aims at replicating real user scenarios to ensure the system’s validation for real world integration and data integrity.

The testing coverage involves various sub-systems for improved detection of issues. This increases the productivity of the application.

Top Five Benefits Of End-To-End Testing

Ensures complete correctness and health of the application

Testing and validating the software application’s performance through all the layers like the data layer, business layer, integration layer, and presentation layer, is important. End to end testing helps to achieve this and ensures an optimal behaviour of the app in a real world scenario.

  •        Increases confidence in the application

It also aims to increase the confidence in the application’s functionality before it is launched. The application is comprehensively tested through different endpoints across various platforms.


  •        Reduces future risks

Robust testing of the application is carried out after every iteration and sprint. This reduces the chances of  failure of the application in the future.


  •        Decreases repetitive efforts

Once  comprehensive testing is carried out, one might not have to put any effort into testing it again. End-to-end testing reduces the probability of frequent breakdowns, hence reducing the repetitive testing efforts.


  •        Reduces costs and time

With the help of an automated testing tool, end-to-end testing decreases the chances of the recurrence of errors. This brings down the testing costs and time.

To conclude:

End-to-end testing scales up the performance of the application from start to end. It helps to test the application’s critical functionalities, such as its communication with the other systems, interfaces, database, network, and other applications. Performing robust end-to-end testing ensures the complete correctness and health of the application, reduces the application’s redundancies, and brings down the testing cost and time.
