我有一个0.13.7 SBT项目,有几个子项目.
其中一个被称为webapp,它在webapp / src / test / java中有许多JUnit测试.
运行时：
sbt webapp/test
只有ScalaTest测试运行,但没有JUnit测试.
我的build.sbt文件的代码段：
libraryDependencies ++= Seq(
"com.novocode" % "junit-interface" % "0.11" % Test
)
lazy val webapp = project
settings(
Seq(
projectDependencies ++= Seq(
....
"org.scalatest" %% "scalatest" % "2.2.2" % Test,"junit" % "junit" % "4.11" % Test,"com.novocode" % "junit-interface" % "0.11" % Test
)
): _*
)
示例JUnit测试：
import org.junit.Test;
public class CodificadorBase64Test {
@Test
public void testPlain() {
byte b[] = {64,127,72,36,100,1,5,9,123};
assertEquals("QH9IJGQBBQl7",CodificadorBase64.encode(b));
}
}
更新(一些更多的研究)：
> webapp/testFrameworks [info] List(TestFramework(WrappedArray(org.scalacheck.ScalaCheckFramework)),TestFramework(WrappedArray(org.specs2.runner.Specs2Framework,org.specs2.runner.SpecsFramework)),TestFramework(WrappedArray(org.specs.runner.SpecsFramework)),TestFramework(WrappedArray(org.scalatest.tools.Framework,org.scalatest.tools.ScalaTestFramework)),TestFramework(WrappedArray(com.novocode.junit.JUnitFramework)) show webapp/loadedTestFrameworks [info] Map(TestFramework(WrappedArray( org.scalatest.tools.Framework,org.scalatest.tools.ScalaTestFramework) ) -> org.scalatest.tools.Framework@65767aeb)
所以JUnit支持是SBT已知的,但没有加载.
调试输出：

使用方法：
> SBT 0.13.9,和
> JUnit 4.x.
相关信息：
> Why don’t junit tests get executed with “sbt test”?
> SBT documentation
解决方法
最后,我发现,我必须将以下设置添加到子项目中：
lazy val webapp = project
settings(
Seq(
projectDependencies ++= Seq(
....
"org.scalatest" %% "scalatest" % "2.2.2" % Test,crosspaths := false,"com.novocode" % "junit-interface" % "0.11" % Test
)
): _*
)
重要的是在子项目中声明junit-interface依赖关系,此外,将crosspaths设置为false.
线索已由this issue提供.
如果主项目没有进行JUnit测试,那么不需要提供所需的测试设置.
另外,为了知道失败的方法和原因,我们需要这个设置：
testOptions in Test := Seq(Tests.Argument(TestFrameworks.JUnit,"-a"))
