Automated Testing in Platform Engineering: Ensuring Quality at Speed

In a fast-paced software development world, ensuring quality while maintaining speed is a balancing act. One of the most effective ways to achieve this equilibrium is through automated testing. Within the scope of platform engineering, automated testing plays an essential role in ensuring that the developed platforms are not only robust but also scalable, secure, and highly reliable. In this post, we’ll delve into the importance of automated testing in platform engineering and how it helps achieve these objectives.

What is Automated Testing?

Automated testing is the practice of running a codebase through an automated test suite, rather than performing manual tests. The primary goal is to increase efficiency, reliability, and repeatability in the testing process. Automated tests can range from unit tests and integration tests to functional, end-to-end, and security tests.

The Need for Automated Testing in Platform Engineering

Platform engineering involves designing, deploying, and maintaining complex software solutions that are often distributed and scalable. Given the intricacy and dynamism of such platforms, manual testing is neither practical nor effective. Here are some reasons why automated testing is crucial:

Speed and Efficiency

Automated tests can be run as often as needed and complete in a fraction of the time it would take to perform manual tests. This speed is essential for Continuous Integration/Continuous Deployment (CI/CD) pipelines, a mainstay in platform engineering.

Consistency and Accuracy

Human error is a given in any manual process. Automated testing eliminates this variable, providing more reliable and consistent test results.


As the platform grows, so does the need for comprehensive testing. Automated testing scales effortlessly, ensuring that even as complexity increases, quality does not suffer.

Coverage and Completeness

Automated testing allows for extensive coverage of your codebase, ensuring that all components, modules, and functionalities are rigorously tested. This is particularly important in platform engineering where even a minor fault can impact the scalability and reliability of the entire system.

Early Detection of Issues

In a platform engineering context, the sooner you identify a problem, the less it will cost to fix. Automated tests integrated into your development pipeline enable early detection of issues, making it easier to maintain the integrity of the platform.

Popular Automated Testing Frameworks in Platform Engineering

JUnit for Java

A stalwart in the Java community, JUnit provides annotations and assertions for writing and running tests, making it easier to test individual components of your platform.

Selenium for Web Testing

This tool is widely used for automating web applications for testing purposes. Selenium supports multiple languages, including Java, C#, and Python.


An evolved version of JUnit, TestNG allows for parallel execution of test methods, providing enhanced support for multi-threaded testing, which is crucial for scalable platforms.

PyTest for Python

Especially popular in Python-based projects, PyTest offers a simpler syntax for writing tests and provides powerful features like fixtures and parameterized testing.

Best Practices in Automated Testing for Platform Engineering

  1. Test Early, Test Often: Implement testing as early as possible in the development lifecycle to catch issues sooner.
  2. Keep Tests Simple and Focused: Each test should represent one logical concept to make it easier to identify issues.
  3. Maintain a Test Database: Keep a separate database for testing to ensure that your tests do not affect your production environment.
  4. Continuous Testing: Integrate your testing suite into your CI/CD pipeline to ensure that code is automatically tested at various stages of development.


Automated testing is an indispensable tool in platform engineering, providing the speed, efficiency, and reliability required in modern software development environments. By integrating automated testing into your CI/CD pipeline, you not only accelerate the development process but also enhance the quality, security, and robustness of your platform.
