过去几天，我一直在努力解决类似的问题； Lily / Jimbo的答案与我的情况不尽相同，但可以帮助我找到正确的方向。

I've been fighting a similar problem for the past few days; Lily / Jimbo's answer didn't quite match my situation, but helped me find the right direction.

在我的情况下，我使用的是第三方库d复制进来。类和测试的程序包名称匹配，但是文件夹结构 not －我的所有测试都直接位于Play的 / test文件夹中，而不是与软件包名称。它没有显示任何错误，但是被破坏了：程序包应该与文件夹匹配。当我在测试下构建正确的文件夹结构并重新编译时，出现了预期的运行方式-> ScalaTest-Suite选项。

In my case, I was using a third-party library that I'd copied in. The package names of the classes and tests matched, but the folder structure did not -- all of my tests were directly in Play's "/test" folder, rather than in folders that matched the package names. This didn't show any errors, but was broken: packages ought to match folders. When I built the right folder structure underneath test, and recompiled, the expected "Run As -> ScalaTest - Suite" options showed up.
