Maven找不到测试 [英] Maven doesn't find tests

问题描述

我有一个Maven项目设置.在项目中，我正在使用JUnit进行单元测试.当我使用mvn test或mvn clean test运行测试时，不会运行任何测试.测试在src/test/java中进行，所有测试均在Test中结束(它们与*Test.java匹配).

I have a Maven project setup. In the project, am using JUnit in for unit testing. When I run tests with mvn test or mvn clean test, no tests are run. Tests are in src/test/java and they all end in Test (they match *Test.java).

这是我的pom.xml:

任何帮助都将不胜感激，因为我一直在努力使它正常工作并且不知道该怎么办.

Any help would be greatly appreciated as I have been trying for many hours to get this to work and have no idea what to do.

将测试类公开后，Maven响应从以下更改:

After making a test class public, the Maven response changed from:

-------------------------------------------------------
 T E S T S
-------------------------------------------------------

Results :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

收件人:

推荐答案

负责运行单元测试的maven-surefire-plugin尚未内置JUnit 5支持.您需要使用提供程序配置插件才能使其正常工作.

JUnit 5 support is not yet built into the maven-surefire-plugin that is responsible for running your unit tests. You need to configure the plugin with a provider in order for it to work.

我使用以下配置:

<properties>
    ...
    <maven-surefire-plugin.version>2.20.1</maven-surefire-plugin.version>
    <junit-5.version>5.2.0</junit-5.version>
</properties>

...
    <plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>${maven-surefire-plugin.version}</version>
      <!-- JUnit 5 Support -->
      <dependencies>
        <dependency>
          <groupId>org.junit.platform</groupId>
          <artifactId>junit-platform-surefire-provider</artifactId>
          <version>1.2.0</version>
        </dependency>
        <dependency>
          <groupId>org.junit.jupiter</groupId>
          <artifactId>junit-jupiter-engine</artifactId>
          <version>${junit-5.version}</version>
        </dependency>
      </dependencies>
    </plugin>
 ...

  <dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>${junit-5.version}</version>
    <scope>test</scope>
  </dependency>
...
