Android - Jacoco代码覆盖忽略了Robolectric测试 [英] Android - Jacoco code coverage ignores Robolectric tests

问题描述

尝试使用Jacoco在Android上的Robolectric测试中获取代码覆盖率但是在创建报告时它只是拒绝承认我的Robolectric测试。

Trying to get Code coverage on my Robolectric tests in Android utilising Jacoco but it simply refuses to acknowledge my Robolectric tests when creating the reports.

我的jacoco.gradle文件如下：

My jacoco.gradle file is as follows:

apply plugin: 'jacoco'

jacoco {
    toolVersion = "0.7.6.201602180812"
}

project.afterEvaluate {

    android.applicationVariants.all { variant ->
        def name = variant.name
        def testTaskName = "test${name.capitalize()}UnitTest"

        tasks.create(name: "${testTaskName}Coverage", type: JacocoReport, dependsOn: "$testTaskName") {
            group = "Reporting"
            description = "Generate Jacoco coverage reports for the ${name.capitalize()} build."

            classDirectories = fileTree(
                    dir: "${project.buildDir}/intermediates/classes/${name}",
                    excludes: ['**/R.class',
                               '**/R$*.class',
                               '**/*$ViewInjector*.*',
                               '**/*$ViewBinder*.*',
                               '**/BuildConfig.*',
                               '**/Manifest*.*']
            )

            sourceDirectories = files(['src/main/java'].plus(android.sourceSets[name].java.srcDirs))
            executionData = files("${project.buildDir}/jacoco/${testTaskName}.exec")

            reports {
                xml.enabled = true
                html.enabled = true
            }
        }
    }
}

通过此设置，我可以获得Coverage报告，但我获得了0％的覆盖率，尽管有Robole src / test / java中的ctric测试。

With this setup I can get Coverage reports but I get 0% coverage despite having Robolectric tests in "src/test/java".

如果我将以下代码添加到该文件中：

If I add in the following code to that file:

android {
    testOptions {
        unitTests.all {
            jacoco {
                includeNoLocationClasses = true
            }
        }
    }
}

Gradle尝试同步时出现以下错误：

I get the following error when Gradle tries to sync:

错误：没有这样的属性：类的includeNoLocationClasses：
org.gradle.testing.jacoco.plugins.JacocoTaskExtension_Decorated

Error:No such property: includeNoLocationClasses for class: org.gradle.testing.jacoco.plugins.JacocoTaskExtension_Decorated

我知道我需要让Gradle 2.13使用这个includeNoLocationClasses值，所以在graddle-wrapper.properties中我有以下内容：

I know that I need to have Gradle 2.13 to use this includeNoLocationClasses value so in graddle-wrapper.properties I have the following:

#Wed Apr 10 15:27:10 PDT 2013
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions-snapshots/gradle-2.13-20160228000026+0000-all.zip

我很确定我是使用Android插件版本1.5运行Gradle 2.13

I am pretty certain I am running Gradle 2.13 with Android plugin version 1.5

在我的应用程序Gradle文件中，我有以下内容：

In my apps Gradle file I have the following:

//...

apply from: 'jacoco.gradle'

//..

testOptions {
    unitTests.returnDefaultValues = true
}

//...

debug {
    testCoverageEnabled true
}

我用来运行保险的命令是：

And the command I use to run the coverage is:

./ gradlew createDebugCoverageReport

./gradlew createDebugCoverageReport

所以我想知道为什么我得到includeNoLocationClasses错误尽管使用了正确的Gradle版本？除此之外，我可能做错了，Jacoco没有在src / test.java中接受Robolectric测试？

So I am wondering why I get the includeNoLocationClasses error despite using the correct Gradle version? And outside of that maybe I am doing something wrong where Jacoco isn't picking up the Robolectric tests in src/test.java ?

推荐答案

我没有完全看到你 build.gradle ，但是要让你拥有那个标志：

I don't see you build.gradle completely, but to have that flag in you have to:

1. 使用 gradle 2.13 +


2. 使用 jacoco 0.7.6.201602180812

1. Use gradle 2.13+
2. Use jacoco 0.7.6.201602180812

您确定使用 gradle 正确的版本。所以，我认为，问题只在于使用了错误的 jacoco 。

You're sure that you use gradle proper version. So, I think, the issue is only in using wrong jacoco.

提及 jacoco {toolVersion =0.7.6.201602180812} 不会影响 gradle DSL。你应该添加更新的 jacoco 插件：

Mentioning jacoco {toolVersion = "0.7.6.201602180812"} doesn't influence gradle DSL. You should add newer jacoco plugin:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'org.jacoco:org.jacoco.core:...'
    }
}

你应该申请插件，你已经在做了：

And you should apply plugin, which you're already doing:

apply from: 'jacoco'

之后这样的配置你不需要 jacoco {toolVersion =...} 更多。

After such configuraiton you don't need jacoco {toolVersion = "..."} more.

注意：考虑要更新到较新的 android gradle 插件， 2.2.x 已经稳定。 jacoco 还有更新的版本 0.7.7.201606060606

Note: consider to update to newer android gradle plugin, 2.2.x is already stable. jacoco also has newer version already 0.7.7.201606060606

还有一个注意事项：如果你请参阅Android Studio中的原始问题，检查您是否默认使用包装器并检查您是否将包装器指向gradle 2.13

One more note: if you see original issue in Android Studio, check that you use wrapper by default and check that you pointed wrapper to gradle 2.13
