In today’s time, modern applications are integrated and interconnected with multiple systems within and outside of the enterprise environment. This makes the entire workflow of the application complicated. Testing and diagnosing errors in these complex applications and their integrations can be challenging by just examining the functional flow. Thus, the solution to ensuring the complete health of an application from all perspective lies in end-to-end testing.
End-to-end testing is a process of testing an application from all the layers – right from the front-end to all the way through the back-end, its interfaces, and final endpoints. Performing end-to-end testing ensures that the application is tested from the users and real world scenarios which helps control and avoid risks by allowing test engineers to:
In addition to these, here are the 5 reasons to perform end-to-end testing:
1. Checks the Health of Back-end
Performing end-to-end testing helps you check the application back-end or database layer. Since an application’s core functioning is dependent on the back-end database, verifying this layer helps identify how healthy the application is and how accurately it can perform the required functions.
2. Identifies Errors in Heterogeneous Environment
With end-to-end testing, you can test applications that are based on distributed, heterogeneous, cloud, and SOA-based environments. It also helps pinpoint problems in the application that comprise of multiple components since it involves 360-degree check.
3. Validates App Behavior over Multi-Tier Architecture & Systems
When it comes to testing and validating the behavior of an application over multi-tier, complex architecture or system workflows, end-to-end testing plays an important role. It helps tests application’s overall functioning and response over connected systems to identify corresponding processes and behavior.

4. Ensures Accurate Interaction & Experience
Since end-to-end testing gives the ability to test the application’s front-end & UI aspects, it helps ensure that the application interacts accurately and provide a consistent experience across different platforms and environments.
5. Conducts Repeatable Tests at Different Points & Processes
End-to-end testing also provides the ability to execute repeatable tests at different processes of applications occurring at different points of transactions.
In addition to above, end-to-end testing also helps verify the complete application and sub-systems flow, increasing the test coverage and confidence in the overall software performance.
Although manual testing can be performed to test an application, there are certain times when the changes and the impact of changes in the application are greater and end-to-end tests needs to be repeated. This inevitably delays the delivery and it also invites risks of failure and increased costs. Thus, to avoid the possible delays, risks, and costs, you should adopt automated testing.
Automating the end-to-end testing allows you to quickly respond to changing business needs since it is stronger and scalable to re-run tests after every fix and adds greater agility to the entire test automation projects. There are several tools that offer end-to-end test automation capabilities, TestingWhiz being one of them.
