Software testing is a crucial step in ensuring an application’s reliability and functionality. As you increase test coverage, the quality of your application testing will increase. Regression testing and end-to-end testing focus on several testing facets to guarantee complete end-user satisfaction.
While End-to-End Testing focuses on the testing of the entire user flow and integrated components, Regression Testing targets specific functionalities and validates the impact of code changes. You need to understand their differences to implement an effective testing strategy.

Visual Summary
Key Differences
Let’s consider an example of a banking application, and look at some of the differences.
| Aspect of testing | End-to-End Testing | Regression Testing |
| Scope | Comprehensive testing that covers testing the entire workflow of an application, and integration with 3rd party applications. Example: Testing the banking application across all functionalities including user logins | Focuses on specific areas impacted by recent code changes. Example: Testing only the payment module after introducing a new payment gateway feature. |
| Test cases | Requires the creation of new test cases and continuous maintenance of test cases | Re-executes the existing test cases. Also involves new test cases based on the code changes |
| Frequency of the tests | Typically performed as part of a major release. | Performed when new code changes or enhancements are done. |
| Time Required | It’s more extensive and time-consuming to run the test cases to cover various scenarios and edge cases | It’s less time-consuming with predefined test cases targeting only the functionalities impacted by the changes. |
When do you need End-to-End Testing?
Think of End-to-End Testing as a detective – examining the app’s interface, testing the user’s journey from initial login to the successful transaction completion.
Pro Tip: Webomates offers code coverage as an optional add-on to AI test automation. Follow these 8 best practices to master end-to-end testing to ensure a seamless user experience and better product quality.
When do you need Regression Testing?
Regression testing is more like a time traveler – traversing across different versions of the application, ensuring that the previous application functionalities are still preserved today even after new changes.
A change in code due to any of the changes made by developers, security, or any other teams could have a domino effect that can affect the whole application.
Pro Tip: The process of regression testing includes selecting the right test cases, and determining the testing frequency and types of regression required to be carried out. Webomates helps you scale up by getting build checks done via its 3 types of regression testing services that provide the maximum quality.
