Question

我在IntelliJ 2019.2。中有一个旧项目。它使用JUnit 5和Mockito。我正在尝试编写一个简单的测试，但是IntelliJ无法解析@Test批注（org.junit.jupiter.api.Test）。如果在“项目”窗口中检查外部库，则可以看到此符号，但是我不明白为什么无法解决该问题。

我的POM是

测试类是

import org.junit.jupiter.Test;

public class InlineMockTest {

   @Test
   void testInlineMock() {

   }

}

Answer 1

由于测试库的范围设置为/src/test/java，并且测试代码在生产代码中不可见，因此测试必须位于test目录下。

无法在JUnit 5项目中解析符号测试
