如何使用 junit5 jupiter 引擎运行 @SpringBatchTest

Question

我正在按照以下链接编写端到端春季批处理作业测试。

https://docs.spring.io/spring-batch/docs/current/reference/html/testing.html#endToEndTesting

这告诉你用 @RunWith(SpringRunner.class) 注释你的测试类，这是 Junit4 的特性，我的测试用例使用 junit5 的老式引擎工作正常。

由于我的其他非批处理相关的测试用例在 jupiter 引擎上运行，我想在我的端到端春季批处理作业测试中使用相同的测试用例。如果我用@ExtendWith(SpringExtension.class) 替换@RunWith(SpringRunner.class)，我可以看到没有一个自动装配的字段被实例化并且具有空值。

由于我对 spring batch 和 jupiter 都是新手，所以我无法理解出了什么问题。

任何指针将不胜感激

Answer 1

你可以摆脱@RunWith(SpringRunner.class)。无需添加 @ExtendWith(SpringExtension.class)，因为 @SpringBootTest 已经添加了 - 至少在当前版本的 Spring Boot 中。

然后你要做的就是改变：

import org.junit.Test;

进入

import org.junit.jupiter.api.Test;

因为这就是告诉 JUnit 平台运行 Jupiter 测试而不是 Vintage 测试的原因。希望能解决您的问题。
