Question

我正在运行 Robolectric 3 rc3 而我无法运行 Robolectric 测试，原因是NoClassDefFoundError在Context。

一周前运作良好。我发现列出here的问题是明显相关的，但我不想降级AS。

这是我的配置：

模块gradle：

// Testing dependencies
testCompile 'org.apache.maven:maven-ant-tasks:2.1.3'
testCompile ("org.robolectric:robolectric:3.0-rc3"){
    exclude module: 'commons-logging'
    exclude module: 'httpclient'
}
testCompile 'com.google.android.gms:play-services:7.0.0'
testCompile ("org.robolectric:shadows-play-services:3.0-rc3"){
    exclude module: 'commons-logging'
    exclude module: 'httpclient'
}
testCompile 'org.robolectric:shadows-support-v4:3.0-rc3'
testCompile 'org.assertj:assertj-core:1.7.0'
testCompile 'com.squareup.okhttp:mockwebserver:1.2.1'

样本单元测试类：

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class)
public class AdServerClientTest {

    @Test(timeout = 7000)
    public void testLongTask() {
        // Fails if the method takes longer than 7 seconds
        ShadowGooglePlayServicesUtil.setIsGooglePlayServicesAvailable(ConnectionResult.SUCCESS);


        assertTrue(false);
    }
}

以下例外：

更新：

我已将Test Class简化为一个断言，并将Exception更改为Parcelable错误。

@Test(timeout = 7000)
public void testLongTask() {
    assertTrue(false);
}

更新2： 我运行./gradlew clean assembleDebug testDebug，结果是java.lang.UnsupportedOperationException: Robolectric does not support API level 22.。真的很奇怪，因为当切换到robolectric 3-RC3时，emulateSdk和reportSdk已被删除：@Config(emulateSdk = 21, reportSdk = 21, constants = BuildConfig.class)。但现在有一些东西需要搜索。

Answer 1

将您在yuor测试课程中的配置更改为

@Config(constants = BuildConfig.class,sdk= 21,  manifest = "src/main/AndroidManifest.xml")

因为org.robolectric:robolectric:3.0-rc3不支持方法emulateSdk和reportSdk

上下文中的Robolectric 3 NoClassDefFoundError
