我正在尝试使用 protobuf 模型编写类的单元测试并在 Android Studio 中运行它们。
例如这是一个简单的转换器测试
class UpdateConfigConverterTest {
private val testable = UpdateConfigConverter()
@Test
fun `should convert from proto model`() {
val url = "https://test.com"
val availableVersion = 1
val requiredVersion = 0
val result = testable.convert(
ProtoUpdateConfig.newBuilder()
.setAvailable(availableVersion)
.setRequired(requiredVersion)
.setUrl("https://test.com")
.build()
)
assertEquals(availableVersion, result.updateAvailableVersion)
assertEquals(requiredVersion, result.updateRequiredVersion)
assertEquals(url, result.url)
}
}
待测类:
internal typealias ProtoUpdateConfig = UpdateConfig
internal class UpdateConfigConverter {
fun convert(source: ProtoUpdateConfig): UpdateConfig =
UpdateConfig(
updateAvailableVersion = source.available,
updateRequiredVersion = source.required,
url = source.url
)
}
proto (实际上是内部消息,但对于 flat 是一样的):
syntax = "proto2";
package proto.api.response;
import "proto/api/KeyValue.proto";
message UpdateConfig {
optional uint32 available = 1;
optional uint32 required = 2;
optional string url = 3;
}
android studio 控制台输出:

尽管如此.gradlew/testDebugUnitTest
成功完成。AS配置等可能有问题。
Android Studio 版本:3.6.0,在 3.5.2 中是一样的。
Protobuf 精简版:3.0.1。
Protobuf gradle 插件:0.8.8。
