我知道这已经被质疑了几次，但我已经没有办法了。

这是我从jUnit 5得到的消息。他找不到任何测试（有800多个）。
我的pom似乎是正确的：

<dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-api</artifactId>
      <version>5.10.0</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-engine</artifactId>
      <version>5.10.0</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-params</artifactId>
      <version>5.10.0</version>
      <scope>test</scope>
    </dependency>

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <version>2.22.2</version>
</plugin>

我的测试命名得很好：

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class AttestationIdentiteCallParamsTest {

    @Test
    void testAttestationIdentiteCallParams() {
}

使用java 11从intelliJ和CMD执行测试。
mvn clean install
200倍
从来都不管用。有主意吗？谢谢

要运行Junit Jupiter测试，最好是对所有需要的工件依赖项使用junit-bom。

<dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.junit</groupId>
        <artifactId>junit-bom</artifactId>
        <version>5.10.0</version>
        <scope>import</scope>
        <type>pom</type>
      </dependency>
    </dependencies>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-engine</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-params</artifactId>
      <scope>test</scope>
    </dependency>
  </dependencies>

也使用最新版本的maven-surefire-plugin

<build>
    <pluginManagement>
      <plugins>
        ...
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>3.1.2</version>
        </plugin>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-failsafe-plugin</artifactId>
          <version>3.1.2</version>
        </plugin>
      </plugins>
    </pluginManagement>
     ..
  </build>

如果你在同一个项目中结合合并JUnit 4和JUnit Jupiter（又名JUnit 5）测试，你必须像这样使用junit-vintage-engine：

<dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.junit</groupId>
        <artifactId>junit-bom</artifactId>
        <version>5.10.0</version>
        <scope>import</scope>
        <type>pom</type>
      </dependency>
      <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.13.2</version>
      </dependency>
    </dependencies>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-engine</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.junit.vintage</groupId>
      <artifactId>junit-vintage-engine</artifactId>
      <scope>test</scope>
    </dependency>
    ..
  </dependencies>

这意味着您可以通过JUnit 5 Vintage引擎运行JUnit 4测试。

你有一个java.lang.ClassNotFoundException为org.junit.platform.engine.support.discovery.SelectorResolver。这个类应该来自工件

<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-engine</artifactId>
    <version>?</version>
</dependency>

修复可能就像将此依赖项添加到您的pom.xml一样简单？
也许您需要从命令行运行以下命令来查看发生了什么

mvn dependency:tree
mvn help:effective-pom

我们已经提到了两个依赖项来解决您的问题。

<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-suite-engine</artifactId>
    <version>1.8.2</version>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.8.2</version>
    <scope>test</scope>
</dependency>

谢谢.
