Intellij ScalaTest与Mockito，测试框架意外退出

Question

我在测试中使用了ScalaTest和Mockito。如果我使用命令行，测试就通过了。但当我使用Intellij运行时，出现了以下错误。它似乎只为测试导入了mockito。

An exception or error caused a run to abort: org.mockito.mock.MockCreationSettings.getSerializableMode()Lorg/mockito/mock/SerializableMode; 
java.lang.NoSuchMethodError: org.mockito.mock.MockCreationSettings.getSerializableMode()Lorg/mockito/mock/SerializableMode;

Answer 1

我在Eclipse中遇到了完全相同的问题，这是因为我有org.mockito.mock.MockCreationSettings类的多个实例。这个类存在于mockito-core.jar和mockito-all.jar中。我不知道为什么开始失败，我在很长一段时间和很多测试中都使用了相同的配置，但问题是我不得不从pom.xml中删除mockito核心依赖项，只保留mockito all。希望能有所帮助
PS:您也可以运行mvn-dependency:tree来检查另一个依赖项是否也带来了mockito-core.jar

Answer 2

它正在MockCreationSettings类中查找名为getSerializableMode()的方法。你的Mockito和PowerMock版本之间似乎不匹配。

试着浏览PowerMock的Maven存储库，并检查您的PowerMock-api-Mockito所依赖的Mockito版本。

Answer 3

我使用的是IntelliJ ultimate 2019.3，scala 2.12.8。我也面临同样的问题。

升级图书馆对我来说很有效。之前：

"org.scalatest" %% "scalatest" % "3.0.5"
"org.mockito" %% "mockito-scala" % "1.5.12"
"org.mockito" %% "mockito-scala-scalatest" % "1.5.12"

之后：

"org.scalatest" %% "scalatest" % "3.1.1"
"org.mockito" %% "mockito-scala" % "1.13.0"
"org.mockito" %% "mockito-scala-scalatest" % "1.13.0"
