Successful software development hinges on maintaining a balance between speed and quality. To stay ahead, many organizations are progressively adopting a shift-left approach. Rather than waiting until the end to catch bugs, this strategy emphasizes conducting quality checks and testing much earlier in the development process. One crucial aspect of this approach is input validation—ensuring that the configurations used in builds are correct right from the start. 

In this tutorial, we’ll walk through how to create a custom input validation framework for Jenkins pipeline. We’ll cover how to validate different input configurations such as JSON files, YAML files, and environment variables. With this system, shift-left framework can catch potential issues early and avoid delays in build and deployment process.
