java使用Roboeletric和Gradle

Question

我正在尝试设置Gradle以使用Roboelectric模拟框架运行Android测试

我有一个具有以下结构的Eclipse工作区：

MyApp
    src
    gen
    test
    ....

MyAppTest
    libs
    test (source folder linked to MyApp.test)
    ....

在Eclipse中手动配置构建路径，测试运行良好

如何在MyAppTest中配置Gradle构建脚本以使用Roboelectric在MyApp项目中运行测试

Answer 1

基于这个solution我能够让这个工作正常进行

总之，尝试将以下内容添加到build.gradle

sourceSets {
    testLocal {
        java.srcDir file('src/test/java')
        resources.srcDir file('src/test/resources')
    }
}

dependencies {
    // Dependencies for your production code here.
    compile 'some.library'

    // localTest dependencies, including dependencies required by production code.
    testLocalCompile 'some.library'
    testLocalCompile 'junit:junit:4.11'
    testLocalCompile 'com.google.android:android:4.1.1.4'
    testLocalCompile 'org.robolectric:robolectric:2.2'
}

task localTest(type: Test, dependsOn: assemble) {
    testClassesDir = sourceSets.testLocal.output.classesDir

    android.sourceSets.main.java.srcDirs.each { dir ->
        def buildDir = dir.getAbsolutePath().split('/')
        buildDir =  (buildDir[0..(buildDir.length - 4)] + ['build', 'classes', 'debug']).join('/')

        sourceSets.testLocal.compileClasspath += files(buildDir)
        sourceSets.testLocal.runtimeClasspath += files(buildDir)
    }

    classpath = sourceSets.testLocal.runtimeClasspath
}

check.dependsOn localTest

别忘了把*Test.java改成@RunWith(RobolectricGradleTestRunner.class)：

public class RobolectricGradleTestRunner extends RobolectricTestRunner {
    public RobolectricGradleTestRunner(Class<?> testClass) throws InitializationError {
        super(testClass);
    }

    @Override
    protected AndroidManifest getAppManifest(Config config) {
        String pwd = YourApplication.class.getProtectionDomain().getCodeSource().getLocation().getPath();
        String root = pwd + "../../../src/main/";

        return new AndroidManifest(
                Fs.fileFromPath(root + "AndroidManifest.xml"),
                Fs.fileFromPath(root + "res"),
                Fs.fileFromPath(root + "assets"));
    }
}

然后，您将能够通过gradle compileDebugJava localTest运行测试。如果我没记错的话，这将需要更新版本的gradle（可能是1.8或1.9）
