我正在尝试找出应用程序的代码覆盖率。我已经为他们编写了黑匣子功能测试。 我正在关注this教程。

我的步骤:

  1. 我从-https://github.com/llatinov/sample-dropwizard-rest-stub下载了源代码 并在pom中添加了以下更改:

    <build>
        <plugins>
            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.7.4.201502262128</version>
                <executions>
                    <execution>
                        <id>jacoco-instrument</id>
                        <phase>test</phase>
                        <goals>
                            <goal>instrument</goal>
                        </goals>
                        <configuration>
                            <skip>${jacoco.skip.instrument}</skip>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
    
  2. 使用mvn clean程序包运行

  3. 使用Java反编译器工具来验证是否检测了类。我可以看到正在检测的代码:

    import org.jacoco.agent.rt.internal_43f5073.Offline;
    
    @Path("/books")
    public class BookService {
      public BookService() {
        arrayOfBoolean[0] = true;
      }
    
      @GET
      @Timed
      @Produces({"application/json"})
      public List<Book> getBooks() {
        boolean[] arrayOfBoolean = $jacocoInit();
        arrayOfBoolean[1] = true;
        return BookDB.getAll();
      }
    }
    
  4. 我使用以下命令启动了该应用程序:

    java -Djacoco-agent.output=tcpserver -Djacoco-agent.destfile=/home/sb/Desktop/jacoco.exec -Djacoco-agent.includes=* -Djacoco-agent.dumponexit=false -Djacoco-agent.address=* -Djacoco-agent.port=6300 -cp /home/sb/Downloads/jacoco/lib/jacocoagent.jar:target/sample-dropwizard-rest-stub-1.0-SNAPSHOT.jar com.automationrhapsody.reststub.RestStubApp server config.yml
    
  5. 我创建了一个Maven测试项目并执行了该应用程序的测试。但是仍然没有创建jacoco.exec文件。我用于测试项目的pom.xml是:

    <project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                <artifactId>rest-assured</artifactId>
                <version>3.0.2</version>
            </dependency>
            <!-- https://mvnrepository.com/artifact/org.testng/testng -->
            <dependency>

                <version>7.1.0</version>
                <scope>test</scope>
            </dependency>
        </dependencies>
        <build>
            <plugins>
                <plugin>

                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>3.0.0-M4</version>
                    <configuration>
                        <systemPropertyVariables>
                            <jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
                        </systemPropertyVariables>
                    </configuration>
                </plugin>
                <plugin>
                    <groupId>org.jacoco</groupId>
                    <artifactId>jacoco-maven-plugin</artifactId>
                    <version>0.8.5</version>
                    <executions>
                        <execution>
                            <id>default-prepare-agent</id>
                            <goals>
                                <goal>prepare-agent</goal>
                            </goals>
                        </execution>
                        <execution>
                            <id>default-report</id>
                            <goals>
                                <goal>report</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </project>
    

请注意,即使关闭了JVM,也不会在指定位置创建jacoco.exec文件。我的喷气机jacocoagent jar文件的权限为755。
