What is Configuration Testing?

Configuration testing is a way to test a system that is still being built on various machines that have different sets of hardware and software configurations. Each hardware and software setup a system or a program supports is used to test how well it works.

When we talk about different combinations of hardware and software, we mean different versions of operating systems, browsers, drivers, memory sizes, hard drive types, CPUs, and so on.

What is Configuration Testing in Software Testing?

It is a type of software configuration testing that focuses on verifying that a software application works correctly under various configurations. Testing configuration ensures that the software behaves consistently across different operating systems, hardware platforms, network environments, and other configurations the software may encounter in the real world.

Software configuration testing is importantl because software applications are often used in different environments, and the software must function correctly in all of these environments. The configurations can vary in terms of hardware specifications, operating systems, network configurations, and other software installed on the system.

To perform configuration testing, testers need to identify the various configurations that the software will encounter in the real world. They can then create a matrix of the different configurations and test cases that need to be executed for each configuration. Testers will execute the test cases and verify that the software behaves correctly under each configuration.

Testing can be challenging due to the extensive range of configurations that require testing. Testers need to carefully plan and prioritize the configurations and test cases to ensure that the most critical configurations are tested first. Automated testing tools can be helpful in executing the test cases across different configurations.

Why is Configuration Testing Important?

Configuration testing is important for ensuring software applications function accurately across various environments. As software is used across different operating systems, hardware platforms, and network environments, it must function correctly in all these settings. 

Testing configuration guarantees that the software behaves consistently across all configurations, allowing testers to identify and resolve any issues. This results in improved software reliability and performance, minimizing the risk of software failures and enhancing user experience. 

So, configuration testing helps to ensure software quality and customer satisfaction.

Types of Configuration Testing

The process of Configuration Testing can be divided into two main categories: 

  • Software Configuration Testing 
  • Hardware Configuration Testing

Software Configuration Testing involves testing an Application Under Test (AUT) on multiple operating systems and browser versions. This testing requires a lot of time for setup, including software installation and uninstallation. It typically starts after Unit Testing and Integration Testing are complete.

Unit Testing vs Functional Testing Comparison ?

Hardware Configuration Testing involves testing physical machines in a laboratory environment with various connections. This testing is used to verify that the application is functioning correctly on the physical machines and connections.

Configuration Testing can also be divided into two types: 

  • Client Level Testing
  • Server Level Testing

Client Level Testing is focused on testing the usability and functionality of the application from the client or user's perspective. Server Level Testing, on the other hand, tests the communication between the software and the external environment after a release to ensure that integration is working correctly.

Objectives of Configuration Testing 

The objectives of Configuration Testing include validating the application's configuration, detecting problems, determining the best system setup, analyzing system efficiency, verifying geographically dispersed environments, ensuring traceability, and managing application components throughout the software development lifecycle.

  1. To ensure that the application is functioning correctly and meeting the requirements for configuration.
  2. To detect and address problems that may not be readily apparent during testing, such as manually producing failures or changing system settings.
  3. To determine the best setup for the test application, including adding or altering hardware resources to analyze system performance.
  4. To analyze system efficiency based on prioritizing, determining how effectively tests were carried out, and obtaining the best system configuration.
  5. To verify the system in a geographically dispersed environment to determine how well it functions regardless of setup changes.
  6. To ensure that problems can be readily reproduced regardless of setup changes.
  7. To document and keep clearly recognizable versions of application components to ensure their traceability.
  8. To determine how manageable the application components are throughout the software development life cycle.

How to Do Configuration Testing 

Here are the steps involved in performing configuration testing:

Identify the different configurations: Identify the various hardware, software, and network configurations that the software may encounter in the real world.

Prioritize the configurations: Prioritize the configurations based on their importance and likelihood of usage.

Create a matrix: Create a matrix of the different configurations and test cases that need to be executed for each configuration.

Prepare the test environment: Prepare the test environment to match the different configurations, including hardware, operating systems, network settings, and other software installed.

Execute the test cases: Execute the test cases for each configuration and document the results. To learn how to create test cases, read our blog.

Analyze the results: Analyze the test results to identify any issues or defects that need to be addressed.

Fix the issues: Fix the issues found during testing and verify the fixes.

Retest: Retest software to ensure the fixes did not introduce new issues.

Report the results: Report the test results to stakeholders and provide recommendations for further improvements.

Automate the testing: Automate the configuration testing process using configuration testing tools to save time and increase accuracy.

You can ensure the software behaves consistently across different configurations and meets the needs of end-users in different environments.

Sample Test Cases Configuration Testing 

Here we have listed some configuration testing example:

  • Verify that the application is connected perfectly with the machine model, assuming all necessary prerequisites are installed.
  • Confirm that the application runs as expected with the machine model when prerequisites are installed.
  • Test the behavior of the application with the machine model when prerequisites are not installed.
  • Ensure that the machine detects the numbers entered in the application system.
  • Verify that the application calculates correctly based on the input.
  • Test that the machine accepts the count from the application system.
  • Confirm that the machine calculates correctly based on the input.
  • Verify that the machine's counting behavior matches the actual cash amount.

These test cases involve verifying the interaction between hardware and software configurations to ensure the software behaves correctly in different environments. By testing the software in different configurations, testers can identify and address any issues, ensuring that the software is reliable and functions as expected in real-world scenarios.
