我有一个maven程序,它编译得很好.当我运行mvn test它时不会运行任何测试(在TESTs标题下说There are no tests to run.).
我用一个超级简单的设置重新创建了这个问题,我将在下面包含以及运行时的输出-X.
单元测试从eclipse运行良好(两者都使用默认的junit包,当我改为包含maven下载的junit.jar时).mvn也test-compile正确地在test-classes下创建了类.我在OSX 10.6.7上使用Maven 3.0.2和java 1.6.0_24运行它.

我有junit-jupiter-api和junit-jupiter-engine作为测试依赖项:
<properties>
<junit.jupiter.version>5.0.1</junit.jupiter.version>
</properties>
<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>

<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>${junit.jupiter.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
我的集成测试是正确命名(下面的**/*IT.java,**/IT*.java或者**/*ITCase.java,其中包括由故障安全默认值,由神火排除默认情况下).
有什么办法可以在Failsafe中使用JUnit 5测试吗？
考虑以下测试类:
public class SomeClass {
@Autowired
private SomeDependency someDependency;
public int inc(int i) {
someDependency.doSomething();
return i + 1;
}
}
如何someDependency在JUnit 5(5.0.1)测试中为Spring Boot 2(2.0.0.M2)应用程序模拟(最好使用Mockito)？当我尝试调用SomeClass#inc(int)它时会产生一个NullPointerException因为没有注入自动连接的依赖项.
我是 IDEA 和 Gradle 生态系统的新手，所以请原谅我提出的基本问题（如果有的话）。
IntelliJ官方宣布支持JUnit 5已经快2年了，不知为何，IDEA仍然讨厌JUnit 5。如果按照官方说明添加JUnit支持，IDEA默认为JUnit 4.12。
无论如何，在阅读之后，我认为我已经在 build.gradle 中正确设置了依赖项：
dependencies {
testCompile("org.junit.platform:junit-platform-launcher:1.2.0")
testCompile("org.junit.jupiter:junit-jupiter-engine:5.2.0")
testCompile("org.junit.vintage:junit-vintage-engine:5.2.0")
}
我的类路径中有所有这些。另外，我发现自己在我的类路径中手动添加了opentest4j-1.1.0.jar。
我按照这些说明为 JUnit 创建了一个新的运行配置。测试确实运行成功，但随着测试运行器的输出，我得到了很多异常，如下所示。难道我做错了什么？
