我的ScalaCheck代码中出现了一个非常罕见但可重复的MalformedInputException。
我无法完美地将它固定下来,或者除了“偶尔”之外还能获得可靠的再现,但是这里的代码我认为会产生问题:
// Generate varying Unicode characters:
val unicodeCharacter = Gen.choose(Char.MinValue, Char.MaxValue).filter(Character.isDefined)
// Generate varying Unicode strings across all legal characters::
def unicodeGenerator(generator: Gen[Char] = unicodeCharacter, minimum: Int = 5, maximum: Int = 20): Gen[String] = Gen.chooseNum(minimum, maximum).flatMap { n =>
Gen.sequence[String, Char](List.fill(n)(generator))
}
// The unit test that I think is occasionally blowing up:
"random strings longer than 20 characters" ! prop { (s: String) => { s.length > 20 must beTrue } }.setGen(unicodeGenerator(unicodeCharacter, 21, 30))
这是我见过的例外:

任何人都有任何想法导致它,更重要如何可靠地防止它?
答案 0 :(得分:2)
当JUnitXmlTestsListener
使用XML.save
保存XML元素时,使用的默认编码为ISO-8859-1
。它应该使用UTF-8
代替。
您可以尝试从构建中删除JUnitXmlTestsListener
,然后use specs2生成junit-xml
个报告:
libraryDependencies += "org.specs2" %% "specs2-junit" % "3.6"
sbt> testOnly *MySpec -- console junitxml
