End-to-End (E2E) Testing is a technique for checking the interaction of the software application with hardware, network connectivity, external dependencies, databases, and other applications with which it is integrated. With this, the system dependency of the software product can be determined. It also maintains better data integrity between the product and the system.
End-to-End Testing checks the software product from beginning to end to ensure that the application seamlessly communicates with the system. This optimizes the data and workflow between the interconnected applications. If any of the applications in the system fails, the entire software can crash. End-to-End Testing can actively avoid such risks by checking the performance, stability, and integration of the software application.
End To End browser testing solution helps to check the system dependency of the browser application. It also tests the application’s integrity with its interfaces. Automating the testing process enables quick, easy, and reliable Testing to check the stability and performance of the application’s workflow from start to end.
When to Apply End-To-End Testing?
With the rapid development of technology, the digital market has witnessed a rise in the software industry. The global business software and services market size was valued at USD 322.91 billion in 2018. As multitudes of software applications are available in the market, it is important to ensure the performance of your product for better receptivity. Thorough Testing before the product is launched more reliable.
End-to-end Testing tests the critical functionalities of the application. It tries to replicate the real user scenarios to check the validation of the system for integration and data integrity. There can be several scenarios to apply E2E testing methods. It is regularly conducted on finished products and systems to test the functioning of the completed system. If the functioning is not satisfactory, a second E2E test will be conducted to determine the segment in which the issue occurs. The problem is fixed, and the application is re-tested.
E2E Testing broadly appeals to:
- Developers: They find this testing method efficient. With E2E Testing, they do not have to bear the workload of thoroughly testing the software application.
- Testers. E2E methods help the testers to write tests in accordance with real-world behavior. It helps them to avoid problems in the application.
- Managers: E2E Testing incorporates the user simulation tests. This helps the managers to understand how the failing test will impact the user.
End-to-End Tests vs. Functional Tests
Functional Testing is used to check a single piece of code or application, while E2E Testing is used for multiple applications and user groups.
While functional Testing validates the result of each test for inputs and outputs, E2E Testing validates the completion of each step in the process. E2E Testing ensures that a process continues to work after the changes are made.
End-To-End Testing Lifecycle
It consists of four components.
- Test planning: It is used to specify the key tasks, schedules, and resources.
- Test design: It is used for test specifications, test case generation, for analysis of the associated risks, usage analysis, and to schedule tests.
- Test execution: It is used to execute test cases. It also documents the testing results.
- Results analysis: It is used for the analysis of test results and to perform additional testing if it is required at any stage.
Top Five Benefits of End-To-End Testing
Ensures Complete Correctness And Health Of The Application
E2E Testing is used to check the performance of the software application through the data layer, business layer, integration layer, and presentation layer. This ensures the correctness and health of the software application.
Increases Confidence In The Application
E2E Testing increases the confidence in the application’s functionality across different devices and platforms.
Reduces Future Risks
E2E Testing checks the performance of the application from beginning to end after every iteration and sprint. The redundancy in the application is reduced with this. It also decreases the risk associated with the failure of the application.
Decreases Repetitive Efforts
E2E Testing is a comprehensive testing method. Hence, it reduces the probability of frequent breakdowns.
Reduces Costs And Time
End-to-end Testing brings down the need for repetitive testing efforts. It also decreases the chances of the recurrence of errors. Hence, it is a cost-effective and time-saving testing method.
Performing robust E2E Testing ensures the correctness of the application. It verifies the system flow and actively detects the issues associated with the subsystem. End to end testing validates the system and its components for integration and data integrity. E2E Testing helps you to refine your product concepts and also assesses the customer appeal of the application. Hence, conducting E2E Testing helps to ensure that your software system is production-ready, layer by layer.
