End-to-end testing

Overview

End-to-end testing allows you to test your API in simulated real-world user scenarios to identify and mitigate potential issues. This collection provides a framework for creating and maintaining end-to-end tests in a centralized location, facilitating collaboration among team members and integration with CI/CD pipelines. Use this template as a reference for organizing your end-to-end tests to help your fellow backend developers or QA engineers speed up their work.

What is end-to-end testing?

End-to-end testing is a comprehensive software testing methodology where the entire application flow, from start to finish, is tested to ensure all components work together as expected. It involves validating the complete system, including its various modules, interfaces, and dependencies, to simulate real-world scenarios and user interactions.

Why is end-to-end testing important?

End-to-end testing is crucial for ensuring the reliability, functionality, and performance of software applications. It helps detect and address issues related to integration, data flow, user experience, and overall system behavior. By mimicking real-world usage scenarios, end-to-end testing identifies potential bottlenecks, errors, and inconsistencies early in the development lifecycle, thereby reducing the risk of encountering critical issues in production.

What does the end-to-end testing template contain?

The end-to-end testing template includes test cases for validating an account creation and fund transfer workflow for the fictional Intergalactic Bank API. It provides a framework for creating and maintaining end-to-end tests in a centralized location, facilitating collaboration among team members and integration with CI/CD pipelines.

How do you perform end-to-end testing with the template?

Here's a step-by-step guide on leveraging this template effectively to perform end-to-end API testing on Postman: Step 1. Explore the template: Get familiar with the template and get the hang of running end-to-end tests on Postman by going through the documentation provided. Step 2. Build user workflows: List the main user workflows or scenarios within your application, such as registration, login, data submission, transaction processing, etc. Step 3. Create test scenarios: Based on the identified user workflows, create test scenarios that cover end-to-end interactions and functionalities. Design tests to simulate real-world user interactions and system behavior. Step 4. Write test scripts: Update the template or create a new collection and set up requests for your user flows. Develop test scripts for each end-to-end scenario on Postman. Bonus: Use Postbot to generate test scripts instantly. Step 5. Execute end-to-end tests: Run the end-to-end tests against your application to validate the entire workflow from start to finish. Monitor the test results for any failures or deviations from the expected behavior.
