Istopper

Istopper is a term used in the field of software development, particularly in the context of continuous integration and continuous delivery (CI/CD) pipelines. It refers to a mechanism or tool designed to halt or stop the progression of a build or deployment process when certain conditions are met. These conditions are typically related to the quality or integrity of the code being built or deployed.

The primary purpose of an istopper is to prevent the release of software that does not meet predefined standards or criteria. This can include failing unit tests, code quality issues, security vulnerabilities, or other forms of technical debt. By stopping the pipeline at these points, istoppers help ensure that only stable and reliable code reaches production environments.

Istopper functionality can be implemented through various tools and plugins, depending on the specific CI/CD system being used. For example, Jenkins, a popular CI/CD tool, offers plugins that can act as istoppers by checking for specific conditions and halting the build process if those conditions are not met.

The use of istoppers is crucial in maintaining the integrity and reliability of software systems, especially in environments where rapid and frequent deployments are common. By catching issues early in the development cycle, istoppers help reduce the risk of bugs and vulnerabilities making it into production, thereby improving overall software quality and stability.
