Let’s define End-to-end (E2E) testing, it makes sure that the application behaves as expected, and application flow from start to end is complete without any issue. It assesses the product system dependencies and ensures that all integrated pieces work together. It’s not just about UI functioning, but also the data encryption and security, information flow between other internally used platforms integrated into the app, proper functioning of the firewall, and more. It is where end-to-end testing comes into the picture to make sure that everything works well under any circumstances. The main reason for this testing is to check the end-user experience by simulating a real case scenario and validating the system for data integrity.
So, how do we perform E2E testing?
- Set up the test environment and analyze the requirements.
- Evaluate the central system with the connected subsystems and define the responsibilities.
- List the methods of testing and the standards to be followed.
- Create test cases and track the requirement matrix.
- Save output and input data before testing each system.
Now, let’s look at some of its benefits:
- Expands test coverage
- Ensures the correctness of the application
- Reduces time to market
- Reduces cost
- Detect bugs
The key metrics to measure success for E2E testing:
Status of test cases: Determine the specific position of the test cases through proper visualization like graphs and compare with planned test cases.
Test progress tracking: The goal of this measurement is to analyze the weekly progress by tracking test completion percentages, such as passed, executed, and valid.
Details of defect status: Issues and bug should be tracked weekly and based on the
distribution of open and closed cases reports generated to track severity and priority.
Availability of test environment: Two vital measurements, the number of operational
hours vs. the time spent on performing end-to-end testing, is tracked.
There are two E2E testing methods.
Horizontal E2E testing automation is testing where UI and integration test cases are automated and designed as integrated actual user scenarios in a single Enterprise Resource Planning (ERP).
Vertical E2E testing automation is a method that refers to testing in layers and tests critical components of a complex computing system that does not usually involve users/interfaces, and each element of a system/product is tested from start to finish.
The components of the E2E testing lifecycle is test planning, design, execution, and results analysis. It can be very time consuming, so it is better to plan before initiating the testing process.
E2E testing is an effective way to guarantee end-user application performance due to the benefits it brings. It is more reliable and widely adopted because of the rapid enhancements in technology like IoT. App’s need smooth functionality because the end-user can be very selective in this competitive market. At Codoid, a QA services company, we focus on how to add value to your E2E testing process, ensuring a timely and successful deployment of your app that is highly rated by the end-user.
