Unlike Scala testing frameworks like ScalaTest (which can also run JUnit test cases), both JUnit and this adapter are pure Java, so you can run JUnit tests with any Scala version supported by sbt without having to build a binary-compatible test framework first. -See LICENSE.txt for licensing conditions (BSD-style). +### Setup Add the following dependency to your `build.sbt`: @@ -12,6 +12,8 @@ Add the following dependency to your `build.sbt`: libraryDependencies += "com.github.sbt" % "junit-interface" % "0.13.2" % Test ``` +**Note**: Organization name has changed to **`"com.github.sbt"`** in 0.12. + JUnit itself is automatically pulled in as a transitive dependency. junit-interface version | JUnit version @@ -23,6 +25,65 @@ JUnit itself is automatically pulled in as a transitive dependency. sbt already knows about junit-interface so the dependency alone is enough.
