Jacoco在运行gradle任务时显示覆盖率为0.0，但在从Intellij运行时显示正确

Question

我正在使用Jacoco插件计算Spring启动应用程序的代码覆盖率。build.gradle的Jacoco配置如下：

jacocoTestReport {
reports {
    xml.enabled false
    csv.enabled false
    html.destination file("${buildDir}/jacocoHtml")
}

afterEvaluate {
    classDirectories = files(classDirectories.files.collect {
        fileTree(dir: it,
                exclude: ['**/models/**',
                          '**/config/**',
                          '**/constants/**',
                          '**/Application.class'])
    })
}

}

和

jacocoTestCoverageVerification {
violationRules {
    rule {
        element = 'PACKAGE'
        excludes = ['some packages']
        limit {
            counter = 'BRANCH'
            minimum = 0.7
        }
    }
}

}

public class SomeClassTest {
private SomeClass someClass;

@Before
public void setUp() throws Exception {
    someClass = new SomeClass(12, 23);
}

@Test
public void shouldSumTwoValues() {
    assertThat(someClass.sum()).isEqualTo(35);
}

}

有人能帮我吗？

Answer 1

在我的例子中，我发现这是因为我将最小值设为1。当我突然将其改为0.9时，它就起作用了

Answer 2

给定src/main/java/SomeClass。java

class SomeClass {

  private Integer value1;
  private Integer value2;

  SomeClass(Integer value1, Integer value2) {
    this.value1 = value1;
    this.value2 = value2;
  }

  Integer sum() {
    return value1 + value2;
  }

}

src/test/java/SomeClassTest。java

import org.junit.*;
import static org.junit.Assert.*;

public class SomeClassTest {
  private SomeClass someClass;

  @Before
  public void setUp() throws Exception {
    someClass = new SomeClass(12, 23);
  }

  @Test
  public void shouldSumTwoValues() {
    assertEquals(35, (int) someClass.sum());
  }
}

和build。格雷德尔

apply plugin: "java"
apply plugin: "jacoco"

dependencies {
  testCompile "junit:junit:4.12"
}

repositories {
  mavenCentral()
}

gradle test JacocoTestReport的执行会在构建/报告/Jacoco/test/html/index.html中生成以下报告

的build.gradle的添加

jacocoTestReport {
  reports {
    xml.enabled false
    csv.enabled false
    html.destination file("${buildDir}/jacocoHtml")
  }

  afterEvaluate {
    classDirectories = files(classDirectories.files.collect {
        fileTree(dir: it,
                exclude: ['**/models/**',
                          '**/config/**',
                          '**/constants/**',
                          '**/Application.class'])
    })
  }
}

jacocoTestCoverageVerification {
  violationRules {
    rule {
        element = 'PACKAGE'
        excludes = ['some packages']
        limit {
            counter = 'BRANCH'
            minimum = 0.7
        }
    }
  }
}

不改变结果/报告，除了在build/JacocoHtml上报告目录的改变。
