PowerMock没有ScalaTest支持,所以我正在尝试使用JUnit来运行我的ScalaTest类,使用@RunWith[classOf[JUnitRunner]]
。使用Maven,您可以配置javaagent模块以急切加载以支持此功能,详见the PowerMock wiki。我需要在SBT中做些什么来获得相同的结果?
name := "my-project"
version := "1.0"
scalaVersion := "2.10.2"
libraryDependencies ++= Seq(
// ... other dependencies above ...
"org.powermock" % "powermock-api-mockito" % "1.5.1" % "test",
"org.powermock" % "powermock-module-javaagent" % "1.5.1" % "test",
"org.powermock" % "powermock-module-junit4-rule-agent" % "1.5.1" % "test",
"com.novocode" % "junit-interface" % "0.10" % "test->default"
)
如图所示,该项目有错误:
[error] Caused by: java.lang.IllegalStateException: PowerMockRule can only be used with the system classloader but was loaded by sbt.classpath.ClasspathUtilities$$anon$1@1cee593
[error] at org.powermock.modules.junit4.rule.PowerMockRule.<clinit>(PowerMockRule.java:28)
[error] ... 55 more
看来SBT有自己的类加载器用于运行与PowerMock需要做的事情相冲突的测试。
答案 0 :(得分:1)
使用SBT 0.12.4,将以下内容添加到build.sbt
fork in Test := true
javaOptions in Test <+= managedClasspath in Test map { (cp: Classpath) =>
val agentJar = cp.find(_.data.name.contains("powermock-module-javaagent")).get
"-javaagent:" + agentJar.data
}
这会导致SBT创建一个用于运行测试的新JVM进程,并添加正确的JVM命令行参数以预加载javaagent模块。
