java - 使用 Powermock 时出现 NoClassDefFoundError

Question

我正在尝试将 powermock 与 easymock 一起使用来测试私有(private)方法和静态方法。我已经从 GITHUB 下载了 jar 并将其依赖项添加到了 build.gradle 中，但是当我运行测试用例时，我不断收到 NoClassDefFoundError 错误。

以下是 gradle 中的堆栈跟踪和依赖项:

java.lang.NoClassDefFoundError: org/powermock/reflect/spi/ProxyFramework

Answer 1

我“认为”您没有指定依赖项的范围。我不知道如何在 Gradle 中做到这一点，但在 Maven 中，我们将“范围”测试“范围”添加到依赖项声明中。
