Grouping tests using JUnit categories

In a well-organized build process, you want lightning-fast unit tests to run first, and provide whatever feedback they can very quickly. A nice way to do this is to be able to class your tests into different categories. For example, this can make it easier to distinguish between faster running unit tests, and slower tests such as integration, performance, load or acceptance tests. This feature exists in TestNG, but, until recently, not in JUnit.

Indeed, this has been missing from the JUnit world for a long time. Using JUnit, I typically use test names (integration tests end in 'IntegrationTest', for example) or packages to identify different types of test. It is easy to configure a build script using Maven or Ant to run different types of test at different points in the build lifecycle. However it would be nice to be able to do this in a more elegant manner.

Migrating Hudson build jobs from one server to another

Sometimes, you may need to move or copy Hudson build jobs from one Hudson instance to another, without copying the entire Hudson configuration. For example, you might be migrating your build jobs to a Hudson instance on a brand new box, with system configuration details that vary from the original machine.
