春季启动启动测试中没有普通的JUnit依赖？

Question

我在start.spring.io中创建了一个全新的项目(Gradle，Java，Boot2.2.6，Jar &Java11)(没有指定依赖项)。我希望在测试类路径中看到vanilla JUnit (junit:junit:x.xx)依赖关系。但找不到它。

执行./gradlew dependencies不包括普通的JUnit，而只包括org.junit.jupiter:junit-jupiter。请参阅下面的相关输出。

默认生成的测试(DemoApplicationTests.java)只有一个import org.junit.jupiter.api.Test;而不是import org.junit.Test。

我遗漏了什么？为了便于参考，下面包含了完整的build.gradle。

Answer 1

org.junit.jupiter:junit-jupiter是JUnit，尽管在5.x版本中。

您似乎期望的普通的junit:junit依赖项是较旧的JUnit版本4.x。
