Junit-5测试用例成功地从命令行运行.我正在使用Maven,当我运行使用mvn clean install
测试用例成功运行但是当使用IntelliJ运行单个测试用例时,它失败并出现以下错误.

我的示例测试类是:
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.ValueSource;
import static org.junit.jupiter.api.Assertions.assertNotNull;
@DisplayName("Pass paramters ")
public class ParametrizedJunit5Test {
@DisplayName("Should pass a non-null message to our test method")
@ParameterizedTest
@ValueSource(strings = {"Hello", "World"})
void shouldPassNonNullMessageAsMethodParameter(String message) {
assertNotNull(message);
}
}
任何帮助将非常感激.

JUnit5和IntelliJ之间存在一些兼容性问题.
根据JUnit文档 ......
建议使用IDEA 2017.3或更新版本,因为这些较新版本的IDEA将根据项目中使用的API版本自动下载以下JAR:junit-platform-launcher,junit-jupiter-engine和junit-vintage-engine.
IntelliJ团队的这篇博文也很有用.有一个评论从谁遇到了同样的错误,你和用户的反应是用户该职位:
我将想法更新到2017.2.6,效果很好.
因此,更新到IntelliJ 2017.3或更新版本,此问题应该消失.
