What is End-to-End(E2E) Testing?

Introduction to E2E testing

E2E Testing

End-to-end testing ensures that the application flow operates as expected by testing the full software product from beginning to end. It specifies the product’s system dependencies and ensures that all integrated components function properly.

Purpose of E2E Testing?

E2E testing is used to test from the perspective of the end-user by recreating a real-world scenario and verifying the system under test and its components for data integrity and integration.

E2E Testing Cycle

E2E Testing Cycle

Test planning: Identifies essential tasks, schedules, and resources.
Test design: Specification of tests, creation of test cases, risk analysis, usage analysis, and test scheduling
Execution: Executes test cases and records the results of the tests.
Result Analysing: Analyzes test results, evaluates testing, and, if necessary, conducts additional testing.

What are E2E Testing Methods?

E2E horizontal testing
A common process that occurs horizontally across different applications and can simply be implemented in a single ERP (Enterprise Resource Planning) solution. Here’s an illustration. Accounts, product inventory status, and shipment details are all included in an e-commerce system’s Web-based application.

E2E vertical testing
This method relates to testing in layers, which means that tests are performed in a hierarchical, sequential order. Each component of a system or product is evaluated from beginning to end to assure quality. Vertical testing is frequently used to evaluate crucial components of a complicated computing system without involving users or interfaces.

Benefits of E2E Testing?

  • Expand test coverage
  • Ensure the accuracy of the application
  • Detect bugs
  • Reduce time to market
  • Cost-cutting
