不能运行考试class"No tests found with test runner 'Junit5'"

Question

我创建了一个简单的 Maven java 应用程序，我试图在其中运行测试用例。

当作为 JunitTestCase 执行运行时，它会弹出一个 window 说明 “没有找到测试运行ner 'JUnit5'".

和 控制台:

我的 pom.xml 有：

 <dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.7.1</version>
    <scope>test</scope>
</dependency>

以及使用： org.junit.jupiter.api.Test

PS:- 我已经在使用 JUnit5 注释了。并使用“运行 as maven-test”零测试运行即将到来。

Answer 1

你只依赖 api，给你例如注释，但是您缺少执行测试的引擎。添加 junit-jupiter-engine 作为依赖项或切换到便利依赖项 junit-jupiter.

查看 Maven 入门示例 (https://github.com/junit-team/junit5-samples/tree/r5.7.1/junit5-jupiter-starter-maven)，了解如何为 junit5 获得最小功能 pom.xml。

不能运行考试class"No tests found with test runner 'Junit5'"
