我知道如何模拟没有构造函数参数的类
,例如, myMock = mock[MockClass]
但是,如果类具有构造函数参数,该怎么办?
更具体地说,我正在尝试模拟Finatra类:ResponseBuilder
https://github.com/imliar/finatra/finatra/blob/master/src/main/scala/com/com/twitter/finatra/finatra/responsebuilder.scala
我在github上找不到测试类,但是答案取决于您想要实现的目标。您不会使用Specs2和Mockito模拟一堂课,您可以在上面监视它以确定是否发生了什么事,这是您可能要实现的示例。
class Responsebuilder(param1: Int, param2: int) {
def doSomething() { doSomethingElse() }
def doSomethingElse() { ...
}
class ResponseBuilderSpec extends Specification with Mockito {
"response builder" should {
"respond" in {
val testClass = spy(new ResponseBuilder(1, 3))
testClass.doSomething()
there was one(testClass).doSomethingElse()
}
}
}
通常会模拟特征作为依赖项,然后将其注入测试类,一旦定义其行为
trait ResponseBuilderConfig { def configurationValue: String }
class Responsebuilder(val config: ResponseBuilderConfig, param2: int) {
def doSomething() { doSomethingElse(config.configurationValue) }
def doSomethingElse(param: String) { ...
}
class ResponseBuilderSpec extends Specification with Mockito {
"response builder" should {
"respond" in {
val mockConfig = mock[ResponseBuilderConfig]
mockConfig.configurationValue returns "Test"
val testClass = spy(new ResponseBuilder(mockConfig, 3))
testClass.doSomething()
there was one(testClass).doSomethingElse("Test")
}
}
}
