如何使用 Wildfly 和 Maven 设置 Jacoco

Question

我尝试在我的 Eclipse IDE 中将 Jacoco 与 Eclemma 插件一起使用，但它不起作用。它在我使用 JBoss 7 但不再使用 Wildfly 9 时有效。我可以运行我的 JUnit 测试没有错误，但代码覆盖率始终为 0%。我正在使用 arquillian。这就是我的 pom.xml :

有什么建议吗？

Answer 1

试试这个配置：

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.7.5.201505241946</version>
    <executions>
        <!--
            Prepares the property pointing to the JaCoCo runtime agent which
            is passed as VM argument when Maven the Surefire plugin is executed.
        -->
        <execution>
            <id>pre-unit-test</id>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
            <configuration>
                <!-- Sets the path to the file which contains the execution data. -->
                <destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
                <!--
                    Sets the name of the property containing the settings
                    for JaCoCo runtime agent.
                -->
                <propertyName>surefireArgLine</propertyName>
            </configuration>
        </execution>
        <!--
            Ensures that the code coverage report for unit tests is created after
            unit tests have been run.
        -->
        <execution>
            <id>post-unit-test</id>
            <phase>test</phase>
            <goals>
                <goal>report</goal>
            </goals>
            <configuration>
                <!-- Sets the path to the file which contains the execution data. -->
                <dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
                <!-- Sets the output directory for the code coverage report. -->
                <outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-failsafe-plugin</artifactId>
     <version>2.15</version>
     <configuration>
         <!-- Sets the VM argument line used when integration tests are run. -->
         <argLine>${failsafeArgLine}</argLine>
     </configuration>
 </plugin>

本指南逐步向您展示如何在您的项目中设置 Jacoco：http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/

第 1 步：使用 jacoco-maven-plugin：

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.7.5.201505241946</version>
    <executions>
        <!--
            Prepares the property pointing to the JaCoCo runtime agent which
            is passed as VM argument when Maven the Surefire plugin is executed.
        -->
        <execution>
            <id>pre-unit-test</id>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
            <configuration>
                <!-- Sets the path to the file which contains the execution data. -->
                <destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
                <!--
                    Sets the name of the property containing the settings
                    for JaCoCo runtime agent.
                -->
                <propertyName>surefireArgLine</propertyName>
            </configuration>
        </execution>
        <!--
            Ensures that the code coverage report for unit tests is created after
            unit tests have been run.
        -->
        <execution>
            <id>post-unit-test</id>
            <phase>test</phase>
            <goals>
                <goal>report</goal>
            </goals>
            <configuration>
                <!-- Sets the path to the file which contains the execution data. -->
                <dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
                <!-- Sets the output directory for the code coverage report. -->
                <outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

第 2 步：使用 maven-surefire-plugin

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.15</version>
<configuration>
    <!-- Sets the VM argument line used when unit tests are run. -->
    <argLine>${surefireArgLine}</argLine>
    <!-- Skips unit tests if the value of skip.unit.tests property is true -->
    <skipTests>${skip.unit.tests}</skipTests>
    <!-- Excludes integration tests when unit tests are run. -->
    <excludes>
        <exclude>**/IT*.java</exclude>
    </excludes>
</configuration>

注意 surefireArgline 属性，它在 jacoco-maven-plugin 中定义，并在 maven-surefire-plugin 中使用。
