Using ScalaTest with Eclipse
For Eclipse users, ScalaTest offers a powerful plugin that provides seamless support for testing in the Scala IDE for Eclipse. Not only does this plugin give Scala programmers the level of test-framework/IDE integration that Java programmers have enjoyed with JUnit, it goes quite a bit farther:
You can use the plugin with any release of ScalaTest, but you'll enjoy the most seamless IDE integration if you use ScalaTest 3.2.17. You can plug it into the latest stable release of the Scala IDE for Eclipse (version 3.0.x). For a nightly build, you'll need to build it by hand by following the steps given in https://github.com/scalatest/scalatest-eclipse-plugin

Information on the features of the integration (and some screenshots (and the source code)) is here:
A video demo of the plugin that I gave back at ScalaDays is here:
