## How do I automatically maintain all of these tests?

![](https://info.diffblue.com/hubfs/PluginPopup/ci-workflow.gif)

Use Diffblue Cover on any CI platform to automatically update your unit tests and catch regressions for every commit - watch [this video](https://www.diffblue.com/video-demo/?utm_source=Plugin\&utm_medium=Whatsnew\&utm_campaign=WhatsNewBox) to learn more.

## Enhancements

* Cover now uses static mocking when the method under test creates temporary files without deleting them. \[Ref: TG-17368]

## Resolved Issues

* Resolved an issue which caused Cover to produce spurious warnings about inconsistent JDK 8 and Spring Core/Spring Boot versions. \[Ref: TG-18055]
* Resolved an issue which caused Cover to report `Error: unknown`, rather than citing the cause of the problem, while writing tests. \[Ref: TG-17692]
