What is Backend Automation Testing?

Backend automation testing refers to the automated testing of backend components of an application. It assists in ensuring that the backend operates correctly without the need for human involvement. This would have cleared your doubt about what backend automation is. When selecting the best backend frameworks, prioritize those that support robust automation testing, enhancing reliability and performance.

Overview and Purpose

The backend is the underlying system that supports a website or application. Databases, servers, APIs, and other elements hidden from users’ view are included. Backend automation testing ensures that these components work as intended without affecting the overall functionality.

It is done to test non-visible parts like databases, web services, APIs, server-side logic, etc., without needing a graphical user interface (GUI). This helps find bugs and errors in the backend before a release.

Types of Backend Testing

• Structural testing – Tests the structure and integrity of the backend code and architecture.
• Schema testing – Validates the structure and integrity of databases by verifying columns, keys, relationships, etc.
• Functional testing – Tests the functionality of APIs, services, server-side logic, databases, etc., against defined specifications.
• Non-functional testing – Checks performance, security, reliability, and other qualitative aspects under varying load conditions.

How to do Backend automation testing tools

Backend testing involves several methods and recommended practices that should be adhered to:

• Test your APIs: Send sample API requests and validate the responses. Check for different status codes like 200 for success, 404 for not found, etc.
• Database testing: Perform queries on the database and validate the results. Ensure that data is inserted, updated, and deleted accurately.
  
• Services/method testing: Trigger backend services or methods directly and validate the expected behavior without UI involvement.
• Load and performance testing: Test how the backend holds up under heavy load by simulating hundreds or thousands of concurrent users. Check for failures or bottlenecks.
  
• Test error handling:  Actively cause network failures and invalid requests at the backend to test how errors are handled.
• Use automation tools: Leverage automation testing tools like Selenium, Katalon, Postman, etc, to write test scripts and automate backend tests. This reduces manual effort and catches errors early.
• Use environment variables: Simulate different environments, like production, staging, etc, by using environment variables during testing.
• Check logging and monitoring: Ensure that logs and metrics are accurately captured at the backend for debugging and monitoring purposes.
• Follow best practices: Modularize code, have good error handling, implement security best practices, etc, to have a robust backend that is easy to test.
