An integration application comprising a plurality of components may be provided. The components may provide connections between systems. The integration application may be configured to allow the systems to exchange data. It may be determined that a new version of a first one of the components is a candidate for release. Prior to release of the new version of the first component, the integration application may be tested using the new version of the first component and an existing version of the first component.
