我正在使用Scala测试来测试我的服务层。我在考试中努力争取获得服务等级的实例。我的测试课如下
class SmsServiceSpec extends BaseSpec with OneAppPerSuite with ScalaFutures {
implicit override lazy val app: FakeApplication = FakeApplication()
"SMS Service" must {
"able to send SMS" in {
val smsService = //not sure how to get instance of class here => app.injector.getInstance[SmsService]
whenReady(smsService.sendSms("9XXXXXXX", "This is test message")) { res =>
res mustBe true
}
}
}
}
根据@easel编辑代码
class SmsServiceSpec extends BaseSpec with OneAppPerSuite with ScalaFutures {
"SMS Service" must {
"able to send SMS" in {
@Inject val smsService: SmsService = null //not sure how to get instance of class here => app.injector.getInstance[SmsService]
whenReady(smsService.sendSms("98XXXXXX", "This is test message")) { res =>
res mustBe true
}
}
}
}
我不确定如何在上述代码中获取SMS服务实例。
谢谢，
最佳答案
您可以使用Guice进行依赖项注入。优良作法是在编译时抽象服务，并在运行时在服务抽象及其实现之间指定绑定。
例如，
SmsServiceImpl类扩展SmsService
bind(classOf [SmsService])。to(classOf [SmsServiceImpl])
这个https://github.com/luongbalinh/play-mongo是使用Play 2.4.2，ReactiveMongo和Guice(用于依赖注入)的简单但标准的应用程序。
