我们配置了排除：

def coverageExcludes() {
    return [
        "com/ourcompany/*Config*",
        "com/ourcompany/ServiceApplication*",
        "com/ourcompany/Shutdown*",
        "com/ourcompany/ShutdownConnector*",
        "com/ourcompany/Tomcat*",
        "com/ourcompany/TomcatCustomConnectorCustomizer*",
        "com/ourcompany/endpoint/exception/**",
        "com/ourcompany/endpoint/util/ObjectMapperBuilder*",
        "com/ourcompany/framework/**",
        "com/ourcompany/helper/ApiHelper*",
        "com/ourcompany/helper/OffsetDateTimeDeserializer*",
        "com/ourcompany/persistence/entity/**",
        "com/ourcompany/persistence/exception/**",
        "com/ourcompany/service/exception/ServiceException*",
        "com/ourcompany/service/model/**",
        "com/ourcompany/v2/**",
        "com/ourcompany/v3/**"
    ]
}

将它们用于jacocoTestReport：

jacocoTestReport {
    reports {
        xml {
            enabled true
        }
        html {
            enabled true
        }
    }
    getExecutionData().setFrom(fileTree(buildDir).include("/jacoco/*.exec"));
    afterEvaluate {
        classDirectories.setFrom(files(classDirectories.files.collect {
            fileTree(dir: it,
                exclude: coverageExcludes()
            )
        }))
        for (Object c : classDirectories) {
            System.out.println(c);
        }
    }
}

并且排除工作：

然后我们尝试在验证任务中使用相同的排除，并将覆盖率失败阈值设置为 0.87，因为这就是覆盖率报告中显示的内容：

jacocoTestCoverageVerification {
    afterEvaluate {
        classDirectories.setFrom(files(classDirectories.files.collect {
            fileTree(dir: it,
                exclude: coverageExcludes()
            )
        }))
        for …

我正在尝试将我的项目设置为运行 JaCoCo，如果测试覆盖率低于 80%，则构建失败。需要注意的是，我想排除一个特定的文件，但我似乎无法做到这一点。我已经在网络上搜索并阅读了大量的 Stack Overflow 答案、博客文章和插件文档，但我无法让任何东西发挥作用。它始终仍然包含我试图排除的文件。

我开始于：

tasks.jacocoTestCoverageVerification {
    violationRules {
        rule {
            limit {
                minimum = "0.8".toBigDecimal()
            }
        }
    }
}

显然，这将包括一切，而且确实如此。根据我所读到的内容，我尝试了以下变体，但没有一个起作用：

tasks.jacocoTestCoverageVerification {
    violationRules {
        rule {
            classDirectories.setFrom(sourceSets.main.get().output.asFileTree.matching {
                exclude("path.to.my.class.HelloWorld")
            })
            limit {
                minimum = "0.8".toBigDecimal()
            }
        }
    }
}

tasks.jacocoTestCoverageVerification {
    classDirectories.setFrom(
            sourceSets.main.get().output.asFileTree.matching {
                exclude("path.to.my.class.HelloWorld")
            }
    )
    violationRules {
        rule {
            limit {
                minimum = "0.8".toBigDecimal()
            }
        }
    }
}

tasks.jacocoTestCoverageVerification {
    violationRules {
        rule {
            limit {
                minimum = "0.8".toBigDecimal()
            }
        }
    }
}
tasks { …

摇篮版本：6.1.1

Android Gradle 插件：4.0.0

当尝试运行我的 jacoco 覆盖范围时，它似乎没有考虑版本。当我查看 HTML 报告时，它显示“使用 JaCoCo 0.7.9.201702052155 创建”，尽管我已经进行了toolVersion = "0.8.5"设置。该报告也没有修复我期望在 0.8.3 中与 Kotlin 相关的问题，作为二次确认，这不起作用。

apply plugin: 'jacoco'

jacoco {
    toolVersion = "0.8.5"
    reportsDir = file("$buildDir/reports")
}

tasks.withType(Test) {
    jacoco.includeNoLocationClasses = true
    jacoco.excludes = ['jdk.internal.*']
}

project.afterEvaluate {
    (android.hasProperty('applicationVariants')
            ? android.'applicationVariants'
            : android.'libraryVariants').all { variant ->
        def variantName = variant.name
        def unitTestTask = "test${variantName.capitalize()}UnitTest"
        def uiTestCoverageTask = "create${variantName.capitalize()}CoverageReport"

        tasks.create(name: "${unitTestTask}Coverage", type: JacocoReport, dependsOn: [
                "$unitTestTask",
                "$uiTestCoverageTask"
        ]) {
            group = "Reporting"

我的公司要求新代码的测试覆盖率达到 90%，对于 Java 代码，我使用 gradle jacoco 插件，这很好；然而，当分支数量开始呈指数增长（夸张一点，可能是几何增长）时，分支覆盖率很难提高到90%。

这是一个非常人为的例子：

public class Application {
    public static void test(boolean a, boolean b) {
        if (a && b) {
            System.out.println("true!");
        } else {
            System.out.println("false!");
        }
    }
}

和测试：

public class ApplicationTests {
    @Test
    public void test() {
        Application.test(true, true);
        Application.test(false, false);
    }
}

覆盖率报告如下所示：

它还说我错过了 4 个分支中的 1 个，或者换句话说，我已经覆盖了 4 个分支中的 3 个（分支覆盖率为 75%）。

如果我在这里增加布尔值的数量，看起来分支的数量是 n*2，其中 n 是布尔值的数量。因此 3 (a,b,c) 变为 6 个分支，10 变为 20 个分支。所以我想我不明白在这种情况下有 6 个或 20 个分支意味着什么。

为了满足这个问题 - 我可以

我正在做一门课程的作业，我需要全面了解这种方法

这些是属性和构造函数，它是咖啡机的程序，这是 Recipe 类

public class Recipe {
private String name;
private int price;
private int amtCoffee;
private int amtMilk;
private int amtSugar;
private int amtChocolate;

/**
 * Creates a default recipe for the coffee maker.
 */
public Recipe() {
    this.name = "";
    this.price = 0;
    this.amtCoffee = 0;
    this.amtMilk = 0;
    this.amtSugar = 0;
    this.amtChocolate = 0;
}

我用过

    /*
 * setPrice test
 */
@Test
public void testSetPrice_1() throws RecipeException {
    r1.setPrice("25");
    r1.setPrice("0");
}

/*

我有一个maven项目,使用"test"-phase以及"integration-test"-phase.在测试阶段,执行JUnit-Tests,在集成测试中有HTMLUnit-tests.我正在使用Jacoco [1] -maven-plugin来测量我的项目的JUnit测试所完成的代码覆盖.在进行集成测试时,我使用maven-embedded-glassfish-plugin启动glassfish服务器并在执行测试之前部署我的应用程序.

可悲但真实,我必须暂时禁用jacoco,因为它与"集成测试"相位不一致.

Jacoco的报告目标是/应该在准备包阶段进行,所以我认为它不应该影响集成测试阶段.但是当我启用jacoco:report时,由于内存大小问题,我的集成测试不再运行[2].

如何停止jacoco:报告影响集成测试阶段？

我正在使用maven和jacoco-maven-plugin进行测试覆盖率报告

我需要将jacoco-agent配置为远程计算机(Linux),我正在运行运行集成测试的脚本

我怎么做到的？

这是我试过的:

                    <execution>
                        <id>prepare-agent-integration</id>

                        <configuration>
                            <destFile>${sonar.jacoco.itReportPath}</destFile>

                            <jacoco.port>22</jacoco.port>
                        </configuration>
                    </execution>

                    <execution>
                        <id>report-integration</id>
                        <goals>
                            <goal>report-integration</goal>
                        </goals>
                        <configuration>
                            <dataFile>${sonar.jacoco.itReportPath}</dataFile>
                            <outputDirectory>${project.basedir}/target/site/jacoco-it</outputDirectory>
                        </configuration>
                    </execution>

我使用EclEmma生成了一个覆盖率报告,其中包含以下路径:

C:/tmp/coverageReport/report.exec

此文件存在,不为空且可读.关于代码覆盖的我的sonnar-runner配置定义如下:

sonar.java.coveragePlugin=jacoco
sonar.junit.reportsPath=C:/tmp/coverageReport/report.exec

分析成功完成,但单元测试覆盖率小部件中没有可见数据.

此外,我在分析过程中得到以下几行:

18:23:45.036 INFO  - parsing C:/tmp/coverageReport/report.exec
18:23:45.037 WARN  - Reports path not found: C:/tmp/coverageReport/report.exec

关于我缺少的任何想法？

我正在开发一个项目,我们正在使用TestNG和JUnit进行测试.

不幸的是,在编写TestNG测试时,他们不会在JaCoCo Coverage报告中考虑.

我写了一个testng.gradle文件,我将其包含在每个build.gradle文件中(这是一个多模块项目):

task testNG(type: Test) { useTestNG() }
test.dependsOn testNG

JUnit和TestNG测试都以这种方式工作.

如果我写testng.gradle这样的话:

test {
    useTestNG()
}

JaCoCo工作正常,但显然只有TestNG测试才能执行.

我该如何解决？这是Gradle的JaCoCo插件中的错误吗？

我有一个maven项目,我想jacoco用于代码覆盖.这是我的pom的相关部分

                </executions>
            </plugin>

所以我能够很好地运行我的测试,并且还可以很好地构建项目.然后我跑了
