我正在使用proto3Android 应用程序，但我遇到了对象相等问题，这使得测试非常困难，尤其是对于验证方法
这是代表问题的单元测试：
@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
}
很明显，该方法equals无法正常工作，检查生成的代码（附在底部）没有相等，生成哈希码。我可以assertThat通过 using.toString方法解决这个问题，但我找不到任何其他验证方式，例如。verify(anyMock).anyMethod(playerCards)
如果检查时不是非常小心，恐怕这也可能会影响我的运行时间。
- 有没有办法生成
equals,hashcode? - 如果没有，我至少可以扩展、覆盖
verify以便toString在检查原始生成的对象时使用吗？
代码片段：
我的原型文件是：
syntax = "proto3";
option java_multiple_files = true;
option optimize_for = LITE_RUNTIME; // existing or not has no effect.
option java_package = "com.package.my";
option java_outer_classname = "Proto";
option objc_class_prefix = "ABC";
package com.package.protos;
message PlayerCards {
int64 playerId = 1;
repeated int32 cards = 2;
}
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：

package com.package.my.nano;
