What is the best solution to build and test source code on each commit to a Cloud Source Repositories repository?

Using Cloud Build with a trigger for each commit is the best solution for building and testing source code on each commit to a Cloud Source Repositories repository. This approach offers a seamless integration with Google Cloud services, ensuring that whenever you push code changes to the repository, Cloud Build can automatically initiate a build process defined by your configuration.

Cloud Build is a fully managed continuous integration and continuous delivery (CI/CD) service that supports various build steps, allowing you to define custom workflows that can include testing, building, and deploying applications. With triggers set to respond to specific events like commits, you'll have an efficient workflow that provides real-time feedback on code changes, helps catch issues early, and streamlines the development process.

Other options may provide CI capabilities, but they lack the automated, cloud-native integration and simplicity that Cloud Build offers. For example, while Jenkins is a powerful tool for continuous integration, deploying it on Google Cloud may require additional overhead for configuration and maintenance. Likewise, using a Compute Engine VM with an open-source CI tool introduces operational complexities, requiring resource management and scaling considerations. The option of using a source code commit trigger linked to a Cloud Pub/Sub topic could facilitate triggering actions, but it doesn’t provide a direct mechanism for build and test processes without
