java - 使用 JUnit 5 和 Spring Boot 2.0.0 进行嵌套测试

Question

我正在尝试为我正在构建的应用程序编写一些嵌套集成测试。

测试是相互建立的，应该测试整个工作流程是否按预期工作。

我试过这样做:

@RunWith(SpringRunner.class)
@SpringBootTest
@ExtendWith(SpringExtension.class)
public class XMLTest {

    @BeforeAll
    public void setUp() {

        // Initialize some things
    }

    @Nested
    @DisplayName("testA")
    class testA {

        @Test
        public void testGettingSomething() {
            ... test something ...
        }

        @Nested
        @DisplayName("testB")
        class testB {

            @Test
            public void testSomethingElse() {
                ... test something else ...
            }
        }
    }
}

但是我总是报错

java.lang.Exception: No runnable methods at 
org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<init>

我想我读到 @Nested 注释来自 JUnit 5，而 Spring 似乎想使用 JUnit 4 亚军。这可能是错误吗？如果是这样，我如何告诉 Spring 使用 JUnit 5 runner？

编辑 1我删除了 RunWith(...) 注释并修复了该错误，但现在我得到了另一个:

这似乎是一个奇怪的错误，因为 Mureinik指出运行者是 JUnit 4 的一个概念。还是我在这里混淆了什么？

相关的应该在底部。

Answer 1

@RunWith 注释和运行器的概念来自 JUnit 4。只需删除该行(但保留 @ExtendWith(SpringExtension.class) 行!)和你应该没问题。
