在Spec2中每次测试前执行reset方法

Question

我在使用Spec2的测试类中定义了测试方法链：

def is =
  "EntriesServlet with logged user" ^
  "POST / request should update entry that user owns" ! updateExistingEntryThatLoggedUserOwns ^
  "POST / request should not update non existing entry" ! notUpdateNonExistingEntry ^
  "POST / request should not update non owner entry" ! notAllowToUpdateNotOwnedEntry
end

在这些方法中，我检查是否调用了定义的mock。但是我需要重新创建一个mock，这样我就可以只计算一个方法的调用次数，而不是全局的。

因此，我需要的是一种无缝定义方法的方法：

 def prepareMocks = {
   serviceMock = mock[MyService]
 }

它将在每个测试方法之前执行，因此我在检查断言之前已经准备好了干净的mock。

我尝试了Spec2的特征BeforeEach和BeforeExample，但它们不是我想要的。

您可以使用case类来实例化您的模拟，并将它们与同时执行的其他示例隔离开来：

import org.specs2._
import specification._
import mock._

class MySpec extends Specification { def is =
  "EntriesServlet with logged user" ^
    "POST / request should update entry that user owns" !        c().updateExistingEntryThatLoggedUserOwns ^
    "POST / request should not update non existing entry" ! c().notUpdateNonExistingEntry ^
    "POST / request should not update non owner entry" ! c().notAllowToUpdateNotOwnedEntry ^
  end

  trait MyService
  case class c() extends Mockito {
    val service = mock[MyService]

    def updateExistingEntryThatLoggedUserOwns = service must not beNull
    def notUpdateNonExistingEntry = ok
    def notAllowToUpdateNotOwnedEntry = ok
  }
}

// here's a similar solution using standardised group names which is a 1.12.3 feature

class MySpec extends Specification { def is =
  "EntriesServlet with logged user" ^
    "POST / request should update entry that user owns"   ! g1().e1 ^
    "POST / request should not update non existing entry" ! g1().e2 ^
    "POST / request should not update non owner entry"    ! g1().e3 ^
  end

  trait MyService
  "POST requests" - new g1 with Mockito {
    val service = mock[MyService]

    e1 := { service must not beNull }
    e2 := ok
    e3 := ok
  }
}
