Cobertura和Jetty

Question

当我使用cobertura在Jetty上运行我的webapp时，我正在尝试获取覆盖报告。通过使用surefire插件，我们已经运行了cobertura进行单元测试。我们还配置了用于运行集成测试的故障保护插件。

我已经(手动)装备了我的war并部署了它。

当使用仅集成测试配置文件运行mvn verify时，cobertura似乎起作用了，因为我在eclipse控制台(我从那里运行jetty )中收到了各种新的警告，可能是因为cobertura更改了字节码。但是，即使在jetty服务器上调用"stop"时，我也无法写入.ser文件。

当我运行mvn cobertura:cobertura时，我得到了一个.ser文件，并且在我的webapp的target/site目录下生成了一个报告。该报告显示0%的覆盖率，因为cobertura:cobertura不运行任何测试。

如何使用故障安全使cobertura工作来运行我的集成测试？还有其他建议吗？

谢谢，本

我通过使用cobertura-it插件解决了这个问题。它扩展了原始的cobertura插件，并允许使用仅报告的goal。此外，我必须运行两个单独的命令(见下文)来测试和生成报告(合并到1个命令不起作用)。这是我的插件配置。

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>cobertura-it-maven-plugin</artifactId>
    <version>2.5</version>
    <configuration>
        <formats>
            <format>html</format>
        </formats>
        <check>
            <haltOnFailure>false</haltOnFailure>
        </check>
    </configuration>
    <executions>
        <execution>
            <id>pre-integration-test</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>cobertura</goal>
            </goals>
        </execution>
    </executions>
</plugin>
<plugin>            
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>7.4.2.v20110526</version>
    <configuration>
        <stopKey>aaaaaaaaaaaaa</stopKey>
        <stopPort>8085</stopPort>
    </configuration>
    <executions>
        <execution>
            <id>start-jetty</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <scanIntervalSeconds>0</scanIntervalSeconds>
                <daemon>true</daemon>
                <classesDirectory>target/generated-classes/cobertura</classesDirectory>
            </configuration>
        </execution>
        <execution>
            <id>stop-jetty</id>

            <goals>
                <goal>stop</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>net.sourceforge.cobertura</groupId>
            <artifactId>cobertura</artifactId>
            <version>1.9.4.1</version>
        </dependency>
    </dependencies>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.10</version>
    <executions>
        <execution>
              <id>integration-test</id>
              <phase>integration-test</phase>
              <goals>
                  <goal>integration-test</goal>
              </goals>
        </execution>
        <execution>
            <id>verify</id>
            <phase>verify</phase>
            <goals>
                <goal>verify</goal>
            </goals>
        </execution>
    </executions>
 </plugin>

所以我运行这个：mvn clean verify

请注意，在Jetty停止后，会出现一些cobertura消息：

[INFO] -------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] -------------------------------------------------------

最后，我使用mvn site生成报告。以下是我的报告配置

Answer 2

也许你需要给你的cobertura-maven-plugin插件配置一些<execution>标签。http://mojo.codehaus.org/cobertura-maven-plugin/instrumentingDeploymentArtifact.html上有一些例子，但这个答案看起来更好：What is the proper way to use Cobertura with Maven 3.0.2
