Question

我有一个简单的HelloWorld Android项目（内置于Eclipse IDE中），我能够在cmd提示符下为此项目成功执行“gradle build”。

我也为它编写了一个简单的JUnit Android测试项目，它在Eclipse中运行良好。

现在我想使用Gradle脚本运行此测试项目或单元测试用例（如果我的理解是错误的！）。我该怎么做？

以下是我正在使用的build.gradle文件。我想知道如何编写脚本代码来自动执行测试用例。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
    }
}
apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
        test {
            java.srcDirs = ['src/test/java']
            resources.srcDirs = ['src/test/resources']         
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')
        androidTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

Answer 1

以下是我使用的内容：

android {
    // ...
    // your stuff
    // ...

    // So Android Studio can nicely edit the test files
    sourceSets {
        androidTest {
            java.srcDir file('src/test/java')
        }
    }
}

// <Task to run tests>
sourceSets {
    unitTest {
        java.srcDir file('src/test/java')
    }
}

configurations {
    unitTestCompile.extendsFrom runtime
    unitTestRuntime.extendsFrom unitTestCompile
}

task unitTest(type: Test, dependsOn: assemble) {
    description = "run unit tests"
    testClassesDir = project.sourceSets.unitTest.output.classesDir
    classpath = project.sourceSets.unitTest.runtimeClasspath
}

check.dependsOn unitTest
// </Task to run tests>

dependencies {
    // ...
    // compile stuff
    // ....

    unitTestCompile files("$project.buildDir/classes/release")
    unitTestCompile 'junit:junit:4.11'
 }

运行测试：

gradlew unitTest

此解决方案尚未实施和测试。正在进行的工作，欢迎提出意见。

仔细阅读所有user guide之后，显然没有对Eclipse Android Test项目的直接支持。原因是新构建系统采用Gradle（和Maven）样式在模块/项目中进行单元测试。

但是因为Eclipse Android Test项目仍然是Android项目，所以有办法尝试

将build.gradle添加到Eclipse Android Test项目中它应该在compile project(':app')

中有dependencies

println GradleVersion.current().prettyPrint()
assert gradle.gradleVersion >= "1.10" // android plugin 0.10 requires Gradle 1.10, 1.11, 1.12

    compile project(':app')
}

    compileSdkVersion 19
    buildToolsVersion "19.0.3"

        main {

            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        androidTest.setRoot('tests')

        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}
//} "boilerplate part"

因为app及其测试现在使多模块项目添加settings.gradle。将它降低1级的最简单方法（两个项目都在的文件夹）
```
include ':app'  
include ':apptest'
```
其他方式是放入兄弟文件夹，例如叫parent
```
includeFlat 'app'
includeFlat 'apptest'
```
在以后的情况下，您需要从该文件夹运行构建（或使用settings.gradle CLI option每次-c位置指定

更新使用gradle进行纯JUnit测试的研究（对于这个问题有点偏离主题），似乎Android Tooling团队忽略了这个问题，打破了其他开发人员试图用更新的android gradle插件做的事情。即使在Android Studio中，它也不是How can I create tests in Android Studio?。关注的唯一组织是Robolectric贡献者，其框架已准备好进行纯JUnit测试https://github.com/robolectric/gradle-android-test-plugin
