End To End Testing


END TO ENDTESTING


What is End-to-End Testing?

End-to-end testing is a technique used to test whether the flow of an application right from start to finish is behaving as expected. The purpose of performing end-to-end testing is to identify system dependencies and to ensure that the data integrity is maintained between various system components and systems.

The entire application is tested for critical functionalities such as communicating with the other systems, interfaces, database, network, and other applications.

Why is End-to-End Testing Important?

With the advancement in technology and considering the fact that the modern software system allows interaction with many subsystems, modern software system has become very complicated. The sub-system could be same or different form the main system or could be within or outside the organization. So, a failure in sub-system can cause adverse effects in the entire system.

The various risks associated with the system can be avoided by performing the following.

  • System flow verification
  • Increasing the test coverage areas
  • Detecting issues associated with the sub-system

However, a complete end-to-end testing includes the following process.

  1. Requirement Analysis
  2. Test environment setup
  3. Hardware and Software requirement analysis
  4. Description of system and all the involved sub-systems
  5. Assigning roles and responsibilities
  6. Testing methods and Standards that are being used
  7. Creating test cases
  8. Recording and saving the I/P and O/P data

BENEFITS FROM ENE TO END TESTING:

1.Ensures Complete Correctness & Health of the Application:

In end-to-end testing, the application is tested and validated at all the layers – data layer, business layer, integration layer and presentation layer. This helps ensure complete correctness and health of the application.

2.Increases Confidence in the Application:

End-to-end testing also increases the confidence in the functioning and performance of the application before its release as the application is tested across different endpoints for different devices and platforms comprehensively.

3.Reduces Future Risks:

In end-to-end testing, the application is tested rigorously after every iteration and sprint. Thus, there are lesser chances of failure and risks in the future.

4.Decreases Repetitive Efforts:

As the application is tested thoroughly, there is no looking back. End-to-end testing reduces the chances of frequent breakdowns and ultimately reduces the repetitive testing efforts.

5.Reduces Costs & Time:

End-to-end testing via automation testing tool reduces errors recurrence, which means the application doesn’t require undergoing repeated testing. This considerably reduces the testing costs and time and helps achieve better productivity in other significant processes.
