org.specs2.mock.Mockito 匹配器未按预期工作 [英] org.specs2.mock.Mockito matchers are not working as expected

问题描述

这是我要运行的代码:

import org.specs2.mock.Mockito
import org.specs2.mutable.Specification
import org.specs2.specification.Scope
import akka.event.LoggingAdapter

class MySpec extends Specification with Mockito {


  "Something" should {
      "do something" in new Scope {

      val logger = mock[LoggingAdapter]

      val myVar = new MyClassTakingLogger(logger)

      myVar.doSth()

      there was no(logger).error(any[Exception], "my err msg")
      }
  }

}

运行时出现以下错误:

[error]    org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
[error]    Invalid use of argument matchers!
[error]    2 matchers expected, 1 recorded:
[error]    -> at         org.specs2.mock.mockito.MockitoMatchers$class.any(MockitoMatchers.scala:47)
[error]
[error]    This exception may occur if matchers are combined with raw values:
[error]        //incorrect:
[error]        someMethod(anyObject(), "raw String");
[error]    When using matchers, all arguments have to be provided by matchers.
[error]    For example:
[error]        //correct:
[error]        someMethod(anyObject(), eq("String by matcher"));

这很有意义，但是 eq("my err msg") 和 equals("my err msg") 都没有完成我得到的工作一个错误.我错过了什么?

Which would make a lot of sense, but neither eq("my err msg") nor equals("my err msg") does the job as I get an error. What am I missing?

推荐答案

当您使用匹配器来匹配参数时，您必须将它们用于所有参数.正如所有参数必须由匹配器提供所指示的那样.

When you are using matchers to match parameters you have to use them for all parameters. as the all arguments have to be provided by matchers indicates.

此外，如果您使用 specs2 匹配器，它需要是强类型的.equals 是一个 Matcher[Any] 但是没有从 Matcher[Any] 到 String 的转换method 接受什么.

Moreover if you use a specs2 matcher it needs to be strongly-typed. equals is a Matcher[Any] but there is no conversion from Matcher[Any] to a String which is what method accepts.

所以在你的情况下你需要一个 Matcher[T] 或一个 Matcher[String].如果你只是想测试相等性，强类型匹配器是 ===

So you need a Matcher[T] or a Matcher[String] in your case. If you just want to test for equality, the strongly-typed matcher is ===

there was no(logger).error(any[Exception], ===("hey"))
