Matrix Builds for Multiple Environments
Utilize matrix strategies to run jobs across multiple versions of languages, operating systems, or configurations in parallel.
What are Matrix Builds?
Welcome to a powerful feature in GitHub Actions: Matrix Builds! Imagine needing to test your code across many different environments, like various operating systems or programming language versions.
Instead of creating a separate workflow for each combination, matrix builds let you define a set of variables, and GitHub Actions will automatically run your jobs for every possible combination of those variables.
Why Use Matrix Builds?
Matrix builds are incredibly useful for:
- Cross-Platform Testing: Ensuring your application works on Windows, macOS, and Linux.
- Multi-Version Compatibility: Testing against different versions of Node.js, Python, or your database.
- Parallel Execution: Running all these tests simultaneously, saving a lot of time.
They help you achieve wider test coverage efficiently.
