How do I use specs2 to confirm a date is equal to another date if their difference is less than 1 second?

I am writing a specs2 test and I need to compare two dates:

import java.util.Date

val date1: Date = getDate1();
val date2: Date = getDate2();

date1 must beEqualToAnotherDate(date2, 1.second)

There is no such routine beEqualToAnotherDate

, how can I do the same in specs2 efficiently?

If you need a custom connector, you can try something like:



import java.util.Date

import org.specs2.matcher.{
  Expectable,
  Matcher,
  MatchResult,
  MatchersImplicits,
  Specification
}

object MySpecs extends Specification with MatchersImplicits {

  def beCloseInTimeTo(date: Date, timeDiff: Int) = new Matcher[Date] {
    def apply[D <: Date](e: Expectable[D]) = 
      result((e.value.getTime - date.getTime) < timeDiff,
        "Dates are nearly at the same time",
        "Dates are different",
        e)
  }

  dateA must beCloseInTimeTo(dateB, timeInMillis)
}

You can use mustB: between:



val millis = date2.getTime()

date1.getTime() must beBetween(millis - 500, millis + 500)
