我试图在Scala中使用PowerMockito来绕过对scala.io.Source.fromURL的调用，NotAMockException是类Source中的静态方法。我已经非常接近让这个工作，但我一直得到import com.sun.xml.internal.messaging.saaj.util.ByteInputStream
import org.junit.Test
import org.junit.runner.RunWith
import org.mockito.Mockito
import org.powermock.api.mockito.PowerMockito
import org.powermock.core.classloader.annotations.PrepareForTest
import org.powermock.modules.junit4.PowerMockRunner
import scala.io.BufferedSource
import scala.io.Source
@RunWith(classOf[PowerMockRunner])
@PrepareForTest(Array(classOf[Source]))
class UtilsTest {
@Test def someTest() {
PowerMockito.mockStatic(classOf[Source])
val a = "hello"
Mockito.doReturn(
new BufferedSource(
new ByteInputStream(a.getBytes, 6), 6))
.when(Source).fromURL(anyString)
}
}
。
when我在org.mockito.exceptions.misusing.NotAMockException:
Argument passed to when() is not a mock!
Example of correct stubbing:
doThrow(new RuntimeException()).when(mock).someMethod();
行上收到以下错误：

知道我做错了什么吗？我把课程模拟得正确，不是吗？

我的build.sbt（显然是瘦身）：
object这里有两点需要注意。
objects妨碍你的测试，所以，如果他们扩展一个特性，你应该耦合到那个，然后注入qazxswpoi作为默认实现，或者你只需将它们包装在你自己的特性中并与之相结合。
