使用 SBT 运行 JUnit 测试 [英] Run JUnit tests with SBT

问题描述

我有一个 0.13.7 SBT 项目，有几个子项目.

I have a 0.13.7 SBT project, with several sub-projects.

其中一个叫做webapp，它在webapp/src/test/java中有很多JUnit测试.

One of them is called webapp, and it has many JUnit tests in webapp/src/test/java.

运行时:

sbt webapp/test

仅运行 ScalaTest 测试，但不运行 JUnit 测试.

only the ScalaTest tests are run, but no JUnit tests.

我的 build.sbt 文件的片段:

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
            )
        ): _*
    )

JUnit 测试示例:

Example JUnit test:

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(更多研究):

> 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 支持被 SBT 知道但没有加载.

So JUnit support is known by SBT but not loaded.

合作:

• SBT 0.13.9 和
• JUnit 4.x.

推荐答案

最后，我发现，我必须在子项目中添加以下设置:

Finally, I've discovered, that I have to add the following settings to the subproject:

lazy val webapp = project
    settings(
        Seq(
            projectDependencies ++= Seq(
                ....
                "org.scalatest" %% "scalatest" % "2.2.2" % Test,
                "junit" % "junit" % "4.11" % Test,
                crossPaths := false,
                "com.novocode" % "junit-interface" % "0.11" % Test
            )
        ): _*
    )

在子项目中声明junit-interface依赖很重要，此外，将crossPaths设置设为false.

It is important to declare the junit-interface dependency in the subproject, and in addition, to set to false the crossPaths setting.

这个问题已经给出了线索​​.

如果主项目没有JUnit测试，则不需要提供所需的测试设置.

If the main project doesn't have JUnit tests, then the needed test settings, don't need to be provided.

另外，为了知道失败的方法和原因，我们需要这个设置:

In addition, for knowing the failing method and the cause, we need this setting:

testOptions in Test := Seq(Tests.Argument(TestFrameworks.JUnit, "-a"))
