如何让Eclipse运行我的所有Groovy单元测试？

I have an Eclipse project with many unit tests written in Groovy. I can run the tests in each individual class using Eclipse's GUnit run configuration. I open this configuration, select the "Run a single test" radio button, and select the class whose tests I want to run. This works fine, however I want to run all of the tests in the the project at once.I have an Eclipse project with many unit tests
