即使条件得到验证，ScalateTest也不会通过

有人能解释一下我的测试报告中怎么会出现这样的句子吗

“列表（数组（109、121、75、101、121））不等于列表（数组（109、121、75、101、121））”

这是完整的输出

Run starting. Expected test count is: 4

以下是我的代码测试：

package eu.codesigner.finagle.ws2redis
import org.scalatest._

class Ws2redisAdapterTest extends FlatSpec with Matchers {

  "Ws2redisAdapter" should "recognize 1-arity commands " in {
    val (cmd, args) = Ws2redisAdapter.adaptRedisCommand("INFO")
    cmd should be("INFO")
    args should be(null)
  }

  it should "recognize 2-arity commands " in {
    val (cmd, args) = Ws2redisAdapter.adaptRedisCommand("GET myKey")
    cmd should be("GET")
    args should be(List("myKey".getBytes()))
  }

  it should "recognize N-arity commands " in {
    val (cmd, args) = Ws2redisAdapter.adaptRedisCommand("ZRANGE myZset 0 -1")
        cmd should be("ZRANGE")
        args should be(List("myZset".getBytes(),"0".getBytes(), "-1".getBytes() ))
  }

  it should "throw Exception if an empty string is given" in {
    a[Exception] should be thrownBy {
      Ws2redisAdapter.adaptRedisCommand("")
    }
  }
}

数组上的相等仅定义为引用相等（如在Java中）。因此你的测试失败了。您可以使用

java.util.arrays.equals

检查两个数组的相等性该死，这是新手犯的错误！：）为了仍然能够使用“应该是”，我修改了测试，用map将字节数组转换为字符串。从这个：args应该是（List（“myKey”.getBytes（）））到这个：args.map（新字符串（））应该是（List（“myKey”））
