Jenkins没有执行Junit测试类（Maven项目）

Question

Jenkins不熟悉，所以我有一个java web项目(maven)和一个单元测试文件。测试文件结构:src/test/Java/preprocessortest . Java

该测试在intellij中成功执行。但是Jenkins并不认为这个测试文件是成功的。

它显示“没有要运行的测试”

我已经尝试了在StackOverflow和整个网络上找到的所有可能的解决方案。任何帮助都将不胜感激。

Answer 1

Surefire似乎无法检测到您的JUnit 5平台。

Surefire如何检测平台引擎

根据Surefire doc，如果没有配置任何内容，Surefire会通过以下算法检测使用哪个JUnit版本:

if the JUnit 5 Platform Engine is present in the project
    use junit-platform
if the JUnit version in the project >= 4.7 and the <<<parallel>>> configuration parameter has ANY value
    use junit47 provider
if JUnit >= 4.0 is present
    use junit4 provider
else
    use junit3.8.1

指定提供程序

您可以尝试指定一个提供程序以确保：（使用 JUnit 5.1.0，JUnit 平台 1.1.0）

<build>
   <plugins>
      <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.19.1</version>
      <dependencies>
         <dependency>
           <groupId>org.junit.platform</groupId>
           <artifactId>junit-platform-surefire-provider</artifactId>
           <version>${org.junit.platform.version}</version>
         </dependency>
         <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>${org.junit.version}</version>
         </dependency>
      </dependencies>
      </plugin>
   </plugins>
</build>

Answer 2

显然，我使用的surefire插件不支持JUnit 5。

所以改变这个

<groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.8.1</version>

到surefire的最新版本

<groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M4</version>
