artdanil的回答没有完全解决我的问题，在emailable报告中测试名称没有更新。
@jersey-city-ninja发布的答案会更新Emailable报告中的名称，但它会为所有Dataprovider值重复相同的最后更新的测试名称，因为pilotg2发布的内容对于使用Dataprovider的测试是正确的，即getTestName方法保持返回方法的最后设置名称，并且Dataprovider的所有测试名称都相同。
所以这里是答案，它是@pilotg2和@jersey-city-ninja发布的答案的组合，并带有额外的步骤来克服重复的方法名称。
注意：这将更新Emailable报告、XML报告、HTML报告和Junit报告中的测试名称。我没有看到它更新Eclipse-TestNg执行视图-如果我找到了什么，我会更新。
