Sonarqube的总体覆盖范围与jacoco报告的覆盖范围不匹配

问题描述

我有一个多模块Android项目，并且发现jacoco报告的内容与Sonarqube报告的内容之间存在差异.该项目还是一个多口味项目，可生成许多不同的变体.我正在使用此插件来帮助我生成所有任务.这些任务会为每个变体生成一个单独的报告.

I have a multi-module Android project and I'm seeing a discrepancy between the coverage that jacoco reports and what Sonarqube reports.The project is also a multi-flavor project that generates a lot of different variants. I am using this plugin to help me generate all of the tasks. The tasks generate an individual report for each variant.

运行我的jacoco报告时，我看到以下内容:

When I run my jacoco reports I see this:

当我运行声纳扫描仪时，我看到以下内容:

When I run the sonar scanner i see this:

我的项目中有一些例外情况，但是即使没有这些例外情况，覆盖范围％s也不匹配.

I have some exclusions on my project,but even without them the coverage %s don't match.

我觉得我可能没有提供与

I feel like I may not be providing the same bytecode as hinted in this question:

这是我的相关信息:声纳版本5.6.

Here is my relevant info:Sonar Version 5.6.

plugins { id "org.sonarqube" version "2.0.1" }

声纳配置:(位于root build.gradle上)

Sonar config: (on root build.gradle)

sonarqube {
    properties {
        property "sonar.projectKey", "com.xxx.myApp"
        property "sonar.projectName", "Android My App"
        property "sonar.projectVersion", "3.0"
        property "sonar.java.binaries", "build/classes"
        property "sonar.coveragePlugin", "jacoco"
        property "sonar.jacoco.reportMissing.force.zero", "false"
    }
}

声纳配置(在app/build.gradle上)

Sonar config (on app/build.gradle)

sonarqube {
    properties {
        property "sonar.sources", "src/main/java"
        property "sonar.tests", "src/test/java"
        property "sonar.java.tests", "src/test/java"
        property "sonar.junit.reportsPath", "build/test-results/myAppGoogleMobileDebug"
        property "sonar.java.binaries", "build/intermediates/classes/myAppGoogleMobile/debug"
        property "sonar.jacoco.reportPath", "build/jacoco/testMyAppGoogleMobileDebugUnitTest.exec"
        property "sonar.coverage.exclusions", coverageExclusions

    }
}

在(app/build.gradle)上的Jacoco配置

Jacoco config on (app/build.gradle)

def coverageExclusions = ['**/AEWatchApp.*', '**/**_Factory.*',
                          '**/QaSettingsActivity.*',
                          'com/aetn/android/tveapps/activities/**',
                          'com/aetn/android/tveapps/test/**',
                          'com/aetn/android/tveapps/app/injection/modules/**',
                          'com/aetn/android/tveapps/app/injection/components/**',
                          'com.aetn.android.tveapps.mock/**',
                          'com/aetn/android/tveapps/databinding/**']


jacocoAndroidUnitTestReport {
    csv.enabled false
    html.enabled true
    xml.enabled true
    excludes += coverageExclusions
}

推荐答案

据我所知，分支覆盖率是相同的:两种情况下均为40％，未发现15个.

As far as I can see branch coverage is the same: 40% in both cases, 15 uncovered.

将指令"(如JaCoCo报告的屏幕快照中所示)与其他任何内容进行比较就像是对苹果和橙子的比较-它们不代表同一件事.请参阅 http://www.eclemma.org/jacoco/trunk/doc/counters. html 关于JaCoCo提供的计数器.并且 http://docs.sonarqube.org/display/SONAR/Metric+Definitions关于SonarQube显示的内容.说明涵盖范围仅在JaCoCo中提供.

And comparison of "instructions" (shown in screenshot of JaCoCo report) with anything else is like comparison of apples and oranges - they don't represent the same thing. See http://www.eclemma.org/jacoco/trunk/doc/counters.html about counters that JaCoCo provides. And http://docs.sonarqube.org/display/SONAR/Metric+Definitions about what SonarQube shows. Instructions coverage is presented only in JaCoCo.

行"(SonarQube屏幕快照中显示的"27.1％")与指令"不同:单行代码通常包含许多字节码指令.因此，例如，如果您总共在10行中有100条指令，并用20条指令覆盖了1行，那么错失的指令占80％，而错失的占90％.

"lines" ("27.1%" shown in screenshot of SonarQube) is not the same as "instructions": Single line of code usually contains many bytecode instructions. So for example if in total you have 100 instructions in 10 lines and cover 1 line with 20 instructions, then missed instructions 80%, but missed lines 90%.

因此，总的来说，没有任何差异，或者至少没有出现在您的屏幕截图中.

So all in all, there is no discrepancy or at least it is not shown on your screenshots.
