What are the Types of E2E Testing Methods? Depending on the end goal of the developers, there are two kinds of testing methods: ● Horizontal E2E Testing This testing method tests the application across various platforms, interfaces, or applications that work together. It aims to ensure the seamless interaction and functionality of the application across different components. This type of testing is often conducted within the scope of a single Enterprise Resource Planning (ERP) system or a similar complex application. Key Points: 1. Cross-Platform Validation: Horizontal E2E testing ensures that the application functions correctly across different platforms, such as different operating systems, browsers, and devices. 2. User-Centric Perspective: This approach is user-centric, simulating real-world scenarios where users interact with the application across various touchpoints. It aims to validate whether users can navigate through different parts of the app without encountering critical errors. 3. Integration Testing: Horizontal E2E testing often involves integration testing, where the integration points between various modules, components, or systems are thoroughly validated. 4. End to End Flow: Test scenarios cover End-to-End flows that span multiple components, applications, or systems. For example, it may involve testing the entire order-to-payment process in an e-commerce application. 5. Usability and Compatibility: It checks the usability and compatibility of the application by considering how users experience the application in different environments. ● Vertical E2E Testing Vertical end-to-end testing, on the other hand, is conducted sequentially and hierarchically, focusing on testing the application's various layers or components from top to bottom. This type of testing ensures that each layer or component interacts correctly with the layers above and below it. Key Points:
- 3. 1. Layered Validation: Vertical E2E testing is organized hierarchically, focusing on validating the functionality and integration of each layer independently and in relation to the entire system. 2. Layer Interaction: It ensures that data and processes flow seamlessly between different layers, including the data layer, presentation layer, and business logic layer. 3. Complex Applications: Vertical E2E testing is particularly suitable for complex applications with multiple interconnected components, where isolating and validating each layer's behavior is crucial. 4. Moving Parts: This method is effective for applications with intricate internal workings and a high degree of interaction between different modules. 5. Non-UI Systems: While horizontal testing often involves user interfaces, vertical E2E testing applies to non-UI systems, like backend services, APIs, or microservices. Importance of End-to-End Testing End-to-end testing is crucial because it provides a holistic view of the application's performance and functionality. It helps detect system dependencies and maintains data integrity throughout the application. This testing method helps identify issues that might not be visible in unit or integration tests. By simulating real user scenarios, end-to-end testing ensures that the application will perform as intended in the real world, enhancing user satisfaction and reducing the risk of production failures. How to Perform End-to-End Testing End-to-end (E2E) testing is a key quality assurance activity that ensures a software application behaves as expected from start to finish. The goal is to mimic real-world scenarios and user interactions to detect system dependencies and ensure that all integrated pieces work together perfectly. Below is a detailed guide on how to carry out end-to-end testing effectively.

It's also essential to define the success criteria for the testing phase, which will help assess whether the test cases have passed or failed. Step 2: Plan the Test Cases Once you have a clear scope, the next step is to plan the test cases. These should cover all the functionalities and user interactions with the application. When designing test cases, consider the following:
- 4. ● User Scenarios: Identify the most common user behaviors and scenarios that need to be tested. ● Data Requirements: Determine the data needed for testing. This includes input data and expected outcomes. ● Integration Points: Pay special attention to the interfaces and integration points where different system components interact. Step 3: Set Up the Test Environment A proper test environment is crucial for E2E testing. This environment should replicate the production environment as closely as possible to uncover any environment-specific issues. Ensure all necessary hardware, software, networks, and other system components are in place and functioning. Step 4: Execute Test Cases With your test cases and environment ready, begin executing the test cases. This step involves: ● Running the Tests: Perform the tests according to the planned scenarios. ● Monitoring: Continuously monitor the system's behavior and outputs. ● Documenting: Keep detailed records of the test results, including any failures and anomalies. Step 5: Analyze Test Results and Report After testing, analyze the outcomes. Compare the actual results with expected outcomes to identify discrepancies. Any failures should be documented and reported to the development team for fixes. Successful tests should also be documented for future reference. Step 6: Perform Regression Testing Once issues are resolved, run regression tests to ensure the changes have not affected existing functionalities. This helps to maintain the stability and reliability of the software. Step 7: Continuous Improvement End-to-End testing is not a one-off activity but a continuous improvement process. Learn from each testing cycle. Refine your test cases, update testing methods, and improve the overall testing strategy to enhance software quality over time. End-to-End Testing Success Metrics To effectively measure the success of end-to-end testing, several key metrics should be considered:
