java - Mockito:mock-maker-inline Android GcmNetworkManager mock java.lang.VerifyError Google Play Services v11.0.2

标签 java android unit-testing mockito google-play-services

使用 mock-maker-inline 模拟 Android 的 GcmNetworkManager 会导致 Google Play 服务版本 11.0 的 java.lang.VerifyError。 2 但不是 10.2.6。

我一直在使用 Mockito 2.2.22 但已更新到最新版本 (2.8.47) 以查看它是否解决了问题。下面提供了两种情况的堆栈跟踪。

Java 版本

$ /Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/java -version
openjdk version "1.8.0_112-release"
OpenJDK Runtime Environment (build 1.8.0_112-release-b06)
OpenJDK 64-Bit Server VM (build 25.112-b06, mixed mode)

最小示例

import com.google.android.gms.gcm.GcmNetworkManager;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;

@RunWith(MockitoJUnitRunner.class)
public class UnitTest {
    private @Mock GcmNetworkManager gcmNetworkManager;

    @Test
    public void doesNothing() { /* empty */ }
}

One of the two will be used. Which one is undefined.

You are seeing this disclaimer because Mockito is configured to create inlined mocks.
You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.

最佳答案

编辑:

这应该在 Mockito 2.9.0 中修复 来源:https://github.com/mockito/mockito/issues/944

如果升级 Mockito，则不需要以下解决方法。

在检测未在调用的方法中正确保留类型信息的混淆类时，可能会发生这种情况。

我设法通过告诉 JVM 不要在我的 build.gradle 中验证单元测试中的类来修复它:

testOptions {
    unitTests.all {
        jvmArgs '-noverify'
    }
}

有人认为这是 Proguard 中的错误，您会看到它，因为 GcmNetworkManager 已使用 Proguard 进行了混淆处理。
