Question

当我尝试运行我的TestFactory时，我得到了这个错误：

但是，当从命令行(mvn test)运行它时，它是工作的。

IDE: IntelliJ 2016.3.3 Java: 1.8项目开发工具包: Java 1.8

Libarier：

ant-1.8.2.jar
hamcrest-core-1.3.jar
junit-4.12.jar
junit-jupiter-api-5.0.0-M3.jar
junit-jupiter-engine-5.0.0-M3.jar
transform-executor-java-4.2.2-SNAPSHOT.jar
transform-util-java-4.6.1-SNAPSHOT.jar
xmlbeans-2.6.0.jar
xmlunit-1.5.jar

我不明白..。

Answer 1

您必须将opentest4j-1.0.0-M1.jar添加到类路径中

将以下依赖添加到您的pom：

<!-- https://mvnrepository.com/artifact/org.opentest4j/opentest4j -->
<dependency>
    <groupId>org.opentest4j</groupId>
    <artifactId>opentest4j</artifactId>
    <version>1.0.0-M1</version>
    <scope>test</scope>
</dependency>

Answer 2

JUnit罐子可能已经过时了。

1. 删除项目依赖项中列出的项
2. 调用@Test上的快速修复程序以找到所需的Jar location
