java - maven故障安全:verify broken when using dependenciesToScan?

Question

我有以下故障安全设置，当我“正常”运行时(=使用 mvn verify，并且不使用 dependencyToScan)，它会按预期工作:

<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，验证会按预期爆炸，并且
• 当集成测试失败时，构建会在验证阶段中断

但是，当我采用完全相同的故障安全设置，并在“test-runner”pom/项目中使用“dependencyToScan”扩展它时，该项目仅从 jar 文件运行测试(因此我不会重新编译/重建每次我想运行集成测试时整个项目):

<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>

发生的情况是这样的:

• 集成测试按预期运行，
• 构建失败，因为它找不到任何要运行的测试(在验证阶段!？ - 见下文)，并且
• 当我删除 failedIfNoTests 时，即使存在测试失败，构建也会报告成功

我检查了各种各样的东西，并尝试了一些东西，所以我不确定我可能会在这里遗漏什么。如果我不使用 dependencyToScan，插件配置显然可以正常工作。

当您使用dependencyToScan时，故障安全插件中是否有可能存在一个错误，该错误会破坏验证业务逻辑？

Answer 1

嗯...首先从您发布的内容看来您的配置是错误的:

您已这样配置:

<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 中得到失败......

但它应该看起来像这样。

<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>

因为调试输出不显示任何类型的配置来代表您在配置中编写的内容(dependencyToScan)。
