如何增加scalacheck控制台输出的字符列宽度？

Question

当运行从sbt consolescalacheck的输出由76 char列宽度的限制：

$ sbt test:console 

import scalaz._ 
import Scalaz._ 
import scalacheck.ScalazProperties._ 
import scalacheck.ScalazArbitrary._ 
import scalacheck.ScalaCheckBinding._

是否有任何方式，以增加限制？

Answer 1

这是不可能改变，因为它是在ScalaCheck（https://github.com/rickynils/scalacheck/blob/master/src/main/scala/org/scalacheck/util/ConsoleReporter.scala）硬编码。我建议在ScalaCheck的Github页面上打开一个问题。

Answer 2

这是不可能的，因为宽度值在ConsoleReporter中被硬编码。但是，如果你是在Properties定义的main运行测试，你可以做到以下几点：

object MyCheck extends Properties("My property check") { 

    override def overrideParameters(p: Test.Parameters) = 
     p.withTestCallback(WideConsoleReporter) 

    ... 

} 

然后在自己的代码，创建一个基于ConsoleReporterWideConsoleReporter。
