mvn故障安全:在使用dependenciesToScan时验证是否已损坏？

Question

我有以下的故障安全设置，当我“正常”运行时(=使用mvn验证，并且不使用dependenciesToScan)，它可以正常工作：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>2.18.1</version>
  <executions>
    <execution>
      <goals>
        <goal>integration-test</goal>
        <goal>verify</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <failIfNoTests>true</failIfNoTests>
    <suiteXmlFiles>
      <suiteXmlFile>src/test/resources/mySuite.xml</suiteXmlFile>
    </suiteXmlFiles>
  </configuration>
</plugin>

• 集成测试按预期运行，
• 如果未指定测试，则验证按预期发生爆炸，以及
• 当集成测试失败时，生成在验证阶段中断。

但是，当我采用完全相同的故障安全设置，并在“测试运行程序”pom / project中使用"dependenciesToScan“扩展它时，它只运行jar文件中的测试(所以我不会每次想运行集成测试时都重新编译/重新构建整个项目)：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>2.18.1</version>
  <executions>
    <execution>
      <goals>
        <goal>integration-test</goal>
        <goal>verify</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <failIfNoTests>true</failIfNoTests>
    <suiteXmlFiles>
      <suiteXmlFile>src/test/resources/mySuite.xml</suiteXmlFile>
    </suiteXmlFiles>
    <dependenciesToScan>
      <dependency>${test.library.groupId}:${test.library.artifactId}</dependency>
    </dependenciesToScan>
  </configuration>
</plugin>

下面是发生的事情：

• 集成测试按预期运行，
• 构建失败，因为它找不到要运行的测试(在验证阶段！？-参见下面)
• 当我删除failIfNoTests时，即使存在测试失败，也会报告构建是成功的。

我检查了各种各样的东西，并尝试了一些东西，所以我不知道我在这里可能遗漏了什么。如果我不使用dependenciesToScan，插件配置显然可以正常工作。

在使用dependenciesToScan时，故障安全插件中是否存在破坏验证业务逻辑的漏洞？

从您发布的内容来看，Hm...first看起来您的配置是错误的：

您已经将其配置如下：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>2.18.1</version>
  <executions>
    <execution>
      <goals>
        <goal>integration-test</goal>
        <goal>verify</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <failIfNoTests>true</failIfNoTests>
    <suiteXmlFiles>
      <suiteXmlFile>src/test/resources/mySuite.xml</suiteXmlFile>
    </suiteXmlFiles>
  </configuration>
  <dependenciesToScan>
    <dependency>${test.library.groupId}:${test.library.artifactId}  </dependency>
  </dependenciesToScan>
</plugin>

我很惊讶你没有从Maven那里得到失败..。

但它应该是这样的。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>2.18.1</version>
  <executions>
    <execution>
      <goals>
        <goal>integration-test</goal>
        <goal>verify</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <failIfNoTests>true</failIfNoTests>
    <suiteXmlFiles>
      <suiteXmlFile>src/test/resources/mySuite.xml</suiteXmlFile>
    </suiteXmlFiles>
    <dependenciesToScan>
      <dependency>${test.library.groupId}:${test.library.artifactId}  </dependency>
    </dependenciesToScan>
  </configuration>
</plugin>

因为调试输出没有显示任何类型的配置，这表示了您在配置(dependenciesToScan)中所写的内容。

Answer 2

我也遇到了同样的问题。尝试使用dependenciesToScan特性从jar中运行测试。我配置的maven pom.xml也有<packaging>pom</packaging>

在运行mvn verify -x时，我得到了以下堆栈跟踪：

Caused by: org.apache.maven.plugin.MojoFailureException: No tests to run!
    at org.apache.maven.plugin.failsafe.VerifyMojo.verifyParameters (VerifyMojo.java:225)

查看org.apache.maven.plugin.failsafe.VerifyMojo的源代码

if ( !getTestClassesDirectory().exists() )
{
    if ( getFailIfNoTests() != null && getFailIfNoTests() )
    {
        throw new MojoFailureException( "No tests to run!" );
    }
}

预期将存在测试源目录。

我首先创建了一个空文件夹target/empty-test-classes，然后将其添加到插件配置中，解决了这个问题：

<testClassesDirectory>${project.build.directory}/empty-test-classes</testClassesDirectory>

2013年开设了一个问题，并就如何解决这个问题提出了其他建议：https://issues.apache.org/jira/browse/SUREFIRE-1024

避免为验证阶段启用failIfNoTests，为集成测试阶段启用它就足够了：

        <plugin>
            <artifactId>maven-failsafe-plugin</artifactId>
            <executions>
                <execution>
                    <id>default</id>
                    <goals>
                        <goal>integration-test</goal>
                    </goals>
                    <phase>integration-test</phase>
                    <configuration>
                        <failIfNoTests>true</failIfNoTests>
                    </configuration>
                </execution>
                <execution>
                    <id>verify</id>
                    <phase>verify</phase>
                    <goals>
                        <goal>verify</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <dependenciesToScan>
                    <dependency>${project.groupId}:cms-it</dependency>
                </dependenciesToScan>
            </configuration>
        </plugin>
