框架

springboot2.0

TestableMock

Jacoco

代码结构

root-pom

-pom1

--jar1

--jar2

-pom2

--jar1

--jar2

根pom下包含多个子pom,每个子pom又包含多个子module jar

覆盖率

在根pom下新建个module,test-module,依赖所有测试可能涉及的jar包

1.test-module的pom中引入jacoco插件

<build>
    <plugins>
      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <version>0.8.6</version>
        <executions>
          <execution>
            <id>report-aggregate</id>
            <phase>test</phase>
            <goals>
              <goal>report-aggregate</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

2.根pom配置,注意surefire的argLine配置

<build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <configuration>
            <testFailureIgnore>true</testFailureIgnore>
            <argLine>
              @{argLine}
              -javaagent:${settings.localRepository}/com/alibaba/testable/testable-agent/${testable.version}/testable-agent-${testable.version}.jar
            </argLine>
          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <version>0.8.6</version>
        <executions>
          <!--first execution : for preparing JaCoCo runtime agent-->
          <execution>
            <id>prepare-agent</id>
            <goals>
              <goal>prepare-agent</goal>
            </goals>
          </execution>
          <!--second execution : for creating code coverage reports-->
          <execution>
            <id>report</id>
            <phase>test</phase>
            <goals>
              <goal>report</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

3.单元测试类所在module(通常是starter模块)的pom,继承父pom的surefire插件

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

执行

mvn test

test-module模块下就会生成聚合报告
