我正在为Android应用程序使用
proto3
，我在对象平等性方面遇到了问题，这使得测试非常困难，尤其是验证方法

下面是一个表示问题的单元测试：

@Test
public void test_equal () {
    PlayerCards playerCards1 = new PlayerCards();
    playerCards1.playerId = 1;
    playerCards1.cards = new int[]{2};

    PlayerCards playerCards2 = new PlayerCards();
    playerCards2.playerId = 1;
    playerCards2.cards = new int[]{2};


    assertThat(playerCards1.toString(), is(playerCards2.toString())); // pass
    assertThat(PlayerCards.toByteArray(playerCards1), 
                          is(PlayerCards.toByteArray(playerCards2))); // pass
    assertThat(playerCards1, is(playerCards2)); // <----- fail

}
我通过gradle build生成文件，并使用以下属性

buildscript {
// ...
    dependencies {
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.0'
    }
}

apply plugin: 'com.google.protobuf'
protobuf {
    protoc {
        artifact = 'com.google.protobuf:protoc:3.1.0'
    }

    generateProtoTasks {
        all().each { task ->
            task.builtins {
                remove java
                javanano {
                    // Options added to --javanano_out
                    option 'ignore_services=true'
                    option 'enum_style=java'
                    option 'generate_intdefs=true'
                }
            }
        }
    }
}


dependencies {
// ...
    compile 'io.grpc:grpc-protobuf-nano:1.0.2'
}
生成的输出：
