我试图在注入(inject)器中创建以测试 api。
The test binding are as follows
class ApiTestModule extends AbstractModule {
def configure(): Unit = {
bind(classOf[Client]).in(classOf[Singleton])
bind(classOf[ApiGetController]).in(classOf[Singleton])
bind(classOf[ApiPostController]).in(classOf[Singleton])
bind(classOf[IndexService]).in(classOf[Singleton])
bind(classOf[PanelService]).in(classOf[Singleton])
bind(classOf[EntitiesService]).in(classOf[Singleton])
bind(classOf[AuthenticatedPublicApiAction]).in(classOf[Singleton])
bind(classOf[RateLimitedApiAction]).in(classOf[Singleton])
bind(classOf[ApiKeyValidatorUpdaterThread]).in(classOf[Singleton])
bind(classOf[ApiKeyValidatorService]).in(classOf[Singleton])
bind(classOf[ArticleFrontService]).in(classOf[Singleton])
}
我在代码中创建了 te 注入(inject)器
val testModule = new AbstractModule() {
def configure() = {
new ApiTestModule().configure(binder())
}
}
val injector = new GuiceApplicationBuilder()
.overrides(testModule).injector()
val apiGetController = injector.instanceOf(classOf[ApiGetController])
我收到以下错误

我认为问题出在我的绑定(bind)模块中，但我无法弄清楚问题是什么。任何帮助将不胜感激。
最佳答案
Mockito 可用于测试。我想你可以像下面的注入(inject)一样尝试用 guice 进行测试
class TestModule extends AbstractModule with MockitoSugar {
val mockClient: Client = mock[Client]
override def configure(): Unit = {
bind(classOf[Client]).toInstance(mockClient)
}
}
很容易模拟和 stub 。如果你想在测试中模拟或 stub ，你可以像这样使用
doReturn("dummyResult").when(testModule.mockClient).someMethod()
关于scala - Guice ，无法创建注入(inject)器，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/43275988/
