如何使用离线检测生成 Jacoco 集成测试报告？

Question

构建工具：Maven

使用离线检测的原因：删除 Powermock 不是一个选项

问题: failsafe 和 surefire 都是运行并且会生成报告。但是，jacoco.exec 是生成的，但 jacoco-it.exec 不是。除了 IT 之外，离线检测、覆盖和报告工作正常。

这是我使用的maven插件配置：

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>default-instrument</id>
            <goals>
                <goal>instrument</goal>
            </goals>
        </execution>
        <execution>
            <id>default-restore-instrumented-classes</id>
            <goals>
                <goal>restore-instrumented-classes</goal>
            </goals>
        </execution>
        <execution>
            <id>default-report</id>
            <goals>
                <goal>report</goal>
            </goals>
        </execution>
        <execution>
            <id>default-report-integration</id>
            <goals>
                <goal>report-integration</goal>
            </goals>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
        <systemPropertyVariables>
            <jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
        </systemPropertyVariables>
    </configuration>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.15</version>
    <executions>
        <execution>
            <id>integration-tests</id>
            <goals>
                <goal>integration-test</goal>
                <goal>verify</goal>
            </goals>
            <configuration>
                <skipTests>${skip.integration.tests}</skipTests>
            </configuration>
        </execution>
    </executions>
</plugin>

为了运行我使用 maven clean install 的测试。

在测试执行结束时，我得到以下输出：

[INFO] 
[INFO] --- maven-failsafe-plugin:2.15:integration-test (integration-tests) @ elune ---
[INFO] Skipping execution of surefire because it has already been run for this configuration
[INFO] 
[INFO] --- jacoco-maven-plugin:0.7.8:report (default-report) @ elune ---
[INFO] Loading execution data file C:\Projects\elune\target\jacoco.exec

[INFO] 
[INFO] --- jacoco-maven-plugin:0.7.8:report-integration (default-report-integration) @ elune ---
[INFO] Skipping JaCoCo execution due to missing execution data file.

另一个可能的指针可能是类的去检测发生在单元测试运行之后但在集成测试之前。但我不知道这是对还是错：

[INFO] 
[INFO] --- jacoco-maven-plugin:0.7.8:restore-instrumented-classes (default-restore-instrumented-classes) @ elune ---
[INFO] 
[INFO] --- maven-jar-plugin:2.6:jar (default-jar) @ elune ---

[INFO] 
[INFO] --- spring-boot-maven-plugin:1.4.2.RELEASE:repackage (default) @ elune ---
[INFO] 
[INFO] --- maven-failsafe-plugin:2.15:integration-test (default) @ elune ---
[INFO] Failsafe report directory: C:\Projects\elune\target\failsafe-reports

知道为什么 jacoco-it.exec 没有出现吗？

Answer 1

我认为带有故障安全插件的集成测试的仪器还没有被烘焙。restore-instrumented-类目标默认为在集成测试阶段之前运行的准备包阶段：http://maven.apache.org/ref/3.3.9/maven-core/lifecycles.html - 因此将目标移至 post-集成测试阶段可能就足够了：

<execution>
  <id>default-restore-instrumented-classes</id>
  <phase>post-integration-test</phase>
  <goals>
    <goal>restore-instrumented-classes</goal>
  </goals>
</execution>

这可能就足够了。否则，您可以更改 surefire 插件的包含模式以也包含集成测试（如果这对您的情况合适）。

Answer 2

设置短语后 jacoco-it.exec 没有出现。命令行是： mvn clean install -Djacoco.version=0.7.8 -DfailOnError=false -Dmaven.test.failure.ignore=true

终于发现问题是我没有在maven-failsafe-plugin中添加配置jacoco-agent.destfile

<plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.16</version>
        <configuration>
          <systemPropertyVariables>
            <jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
          </systemPropertyVariables>
        </configuration>
      </plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>

          <systemPropertyVariables>
            <jacoco-agent.destfile>target/jacoco-it.exec</jacoco-agent.destfile>
          </systemPropertyVariables>
        </configuration>
    <executions>
        <execution>
            <id>integration-tests</id>
            <goals>
                <goal>integration-test</goal>
            </goals>
        </execution>
    </executions>
</plugin>

        </executions>
      </plugin>
</plugins>

@rhinoceros.xn 这是对我有用的插件配置。但是我用mvn clean install到运行这个

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>default-instrument</id>
                    <goals>
                        <goal>instrument</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-restore-instrumented-classes</id>
                    <phase>post-integration-test</phase>
                    <goals>
                        <goal>restore-instrumented-classes</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-report</id>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-report-integration</id>
                    <goals>
                        <goal>report-integration</goal>
                    </goals>
                </execution>
            </executions>
