While many testing approaches focus on specific aspects and functional and non-functional attributes, there comes the need to test the application’s ability to complete all its required services from the starting point to a significant closing mark.
In this article, we will investigate one method that we use atQ-Prosto fully scan software systems and make sure they are compliant with QA standards. This method is called End-to-End testing (E2E).
What is End-to-End Testing?
End-to-end testing is a testing approach used to confirm that application software works or behaves as expected from start to finish. The primary purpose is to ensure the software has all integrated components working well.
E2E activities include examining the system under real-life scenarios to see how it behaves under intended use.
E2E is also one way to identify the system’s dependencies and validate data integrity for users.
Importance of End-to-End Testing
Most software systems consist of multiple sub-systems that correlate with each other, and the success of the entire system depends on all those systems working well. A way to check for that correlation is by E2E tests, and by doing so, we can avoid system crashes.
E2E tests work like any other testing approach. It requires test cases and test reports. The objective is to look for bugs and defects and identify potential bottlenecks that the systems could be facing during use.
Types of End-to-End Testing
The following are two types of methods for E2E tests that are commonly used:
Horizontal E2E testing
This type of E2E involves testing the system on a horizontal scope, which means looking at the basic functions used in an application. This comes closer to the actual journey of the user without diving deep into specific expert knowledge. Take for example creating an account and deleting an account.
Vertical E2E testing
This form of E2E is a bit more for the complex areas of the systems, meaning we are now diving deep into aspects beyond the simple user interface. Take for example testing each component of the system separately and paying attention to data through the UI, API, and database layers.
Automated vs. Manual End-to-End Testing
E2E tests can be performed manually for the most part, a testing expert would simply follow the normal flow of the application use it as intended, and record any occurrence of defects or bugs.
However, software testing services are involved in frequently testing more complex software systems that include an API and database where there could be no concern to the UI for the tester. In that case, we rely on automated methods to conduct a thorough analysis of the system by calling multiple complex orders via automation software.
Tools for Automated End-to-End Testing
End-to-end testing can help developers scale up the quality of their applications by guaranteeing that the system is bug-free throughout its entire course.
End-to-end testing is a testing method used to validate application software performance and behavior as expected from start to finish.
E2E testing can be both automated and manual depending on the complexity of the components we are testing.
Q-Pros is a leading testing provider with years of experience that testifies to that. We believe that End-to-End testing is vital for QA purposes. While establishing our testing planes and phases, we make sure to include E2E as an essential stage for QA.
