我正在使用 gradle 尝试 Android Studio 0.5.8。

我当前的根构建文件:

buildscript {
    repositories {
        mavenCentral()
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
        classpath 'com.novoda.gradle:robolectric-plugin:0.0.1-SNAPSHOT'
    }
}

allprojects {
    repositories {
        mavenCentral()
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots'
        }
    }
}

我的应用程序 build.gradle:

apply plugin: 'android'
apply plugin: 'robolectric'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    dependencies {
        androidTestCompile 'org.robolectric:robolectric:2.3-SNAPSHOT'
        androidTestCompile 'org.mockito:mockito-all:1.9.5'
        androidTestCompile 'junit:junit:4.+'
    }

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.1.0'
}

task addTest {
    def src = ['src/test/java']
    def file = file("app.iml")

    doLast {
        try {
            def parsedXml = (new XmlParser()).parse(file)
            def node = parsedXml.component[1].content[0]
            src.each {
                def path = 'file://$MODULE_DIR$/' + "${it}"
                def set = node.find { it.@url == path }
                if (set == null) {
                    new Node(node, 'sourceFolder', ['url': 'file://$MODULE_DIR$/' + "${it}", 'isTestSource': "true"])
                    def writer = new StringWriter()
                    new XmlNodePrinter(new PrintWriter(writer)).print(parsedXml)
                    file.text = writer.toString()
                }
            }
        } catch (FileNotFoundException e) {
            // nop, iml not found
        }
    }
}

gradle.projectsEvaluated {
    preBuild.dependsOn(addTest)
}

tasks.withType(Test) {
    scanForTestClasses = false
    include "**/*Test.class"
}

这是我的测试应用程序类:

public class NSApplicationTest extends NSApplication {

    @Override
    public Context getContext() {
        return mock(Context.class);
    }

    @Override
    public AlarmManager getAlarmManager() {
        return mock(AlarmManager.class);
    }
}

此配置的问题是任务 addTest 正在加载 NSApplicationTest 类作为测试，它失败了:

   com.pack.scheduler.app.NSApplicationTest > initializationError FAILED
        java.lang.Exception  

So I tried to change the name extension to see if this would fix everything but I'm still getting the same error. Then I tried with @Ignore on NSApplicationTest.

关于如何解决这个问题有什么想法吗？

最佳答案

您不需要编写自己的 TestRunner。只需为您的测试应用程序类使用正确的命名模式:TestNSApplication(而不是 NSApplicationTest)

我经常看到以下模式:

• *测试标记测试执行类
• Test* 标记类扩展以使类可测试

我希望您已经知道此类必须与您的应用程序类具有相同的包。
