无法让Jacoco使用离线工具与Powermockito合作

提问于

鉴于Jacoco在“动态”工具时不能很好地与PowerMockito配合使用，我一直在尝试配置离线工具，希望这能为我提供适用于使用PowerMockito的类的单元测试覆盖率 .

我已经将我的pom设置如下，但我的测试课程仍然保持0％的覆盖率 . 任何帮助都非常感激，因为它让我慢慢疯狂！

这是我的课程：

public class Utils {

    private Utils() {

    }

    public static String say(String s) {
        return "hello:"+s;
    }
}

这是我的测试：

@RunWith(PowerMockRunner.class)

@PrepareOnlyThisForTest(Utils.class)
@PowerMockIgnore("org.jacoco.agent.rt.*")
public class UtilsTest {

    @Test
    public void testSay() throws Exception {
        PowerMockito.mockStatic(Utils.class);
        Mockito.when(Utils.say(Mockito.anyString())).thenReturn("hello:mandy");
        assertEquals("hello:mandy", Utils.say("sid"));
    }

}

我运行mvn clean install生成jacoco.exe

覆盖率报告（使用ant脚本从jacoco.exec生成）： -

    我和JaCoCo On-the-fly和PowerMock有同样的问题 . 每次都会生成0％的代码覆盖率

    发现JaCoCo版本0.7.7.201606060606和PowerMock版本1.6.2兼容并且代码覆盖成功生成 .

    我看到了同样的行为，虽然在GitHub问题上跟随线程之后，似乎在1.6.5中修复了，这对我来说是正确的 .

    希望这会在以后让人头疼:) .

    工作配置：

    • jacoco-maven-plugin 0.7.7.201606060606

    • powermock 1.6.5

    我没有使用离线仪器 .

    我使用PowerMock的javaagent使它工作 . 看到这里：https://code.google.com/p/powermock/wiki/PowerMockAgent

    删除 @RunWith 注释，按照上面的链接中的说明放置 PowerMockRule . 把它公之于众 .

    将以下行放在maven-surefire-plugin配置中：

    -javaagent:${org.powermock:powermock-module-javaagent:jar}

    我也面临同样的问题 . 我能够部分生成报告 . 我已将这两个标签用于我的测试用例@RunWith（PowerMockRunner.class）@PrepareForTest（{}） . 并且我没有为我使用上述标签的测试案例生成报告 . 但是对于其中一个测试用例，只有@RunWith（PowerMockRunner.class）这个标签 . 不知何故，报告是针对该案例生成的 . 而且我从未使用过离线仪器 . 当我尝试使用离线工具时，我收到错误，说该课程已经过检测 . 我尝试了各种方案，并遵循各种链接，但无法生成报告 . 最后根据上面的评论我将我的powermock版本从1.5.5升级到1.6.5，我能够生成报告 . 以下是我的 pom.xml 条目

    以下是我在 pom .xml for maven-surefire-plugin 的报名

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
      <configuration>
            <argLine>@{argLine}</argLine>
            <skipTests>false</skipTests>
            <testFailureIgnore>true</testFailureIgnore>
        </configuration>
    </plugin>

    @ was set as a property

    <properties>
    <argLine>-noverify -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m</argLine>
</properties>

    And upgraded my powermock version from 1.5.5 to 1.6.5 . 最后，我可以在我的测试用例中使用以下标记的类看到我的报告生成 @RunWith(PowerMockRunner.class) @PrepareForTest({})

    我最终使用离线仪器和Jacoco（类似于你所做的）与sonar一起使用，我能够从中获得覆盖率数字 .
