我有一个返回 Try 对象的方法:
I have a method that returns a Try object:
def doSomething(p: SomeParam): Try[Something] = { // code }我现在想用 ScalaTest 测试这个.目前我是这样做的:
I now want to test this with ScalaTest. Currently I am doing it like this:
"My try method" should "succeed" in { val maybeRes = doSomething(SomeParam("foo")) maybeRes.isSuccess shouldBe true val res = maybeRes.get res.bar shouldBe "moo" }然而,检查 isSuccess 是否为 true 看起来有点笨拙,因为对于 Options 和 Sequences 来说,should be(empty) 和不应该是(空).我找不到像 should be(successful) 这样的东西.
However checking for isSuccess to be true looks a bit clumsy because for Options and Sequences there are things like should be(empty) and shouldNot be(empty). I cannot find anything like should be(successful).
这是否存在或者我的方法真的是要走的路?
Does this exist or is my approach really the way to go?
推荐答案另一种可能是做
import org.scalatest.TryValues._ maybeRes.success.value.bar shouldBe "moo"这将给出一条消息,表明 Try 没有成功,而不是在 maybeRes.get 中抛出异常.
This will give a message indicating the Try was not a success, instead of throwing the exception in maybeRes.get.
Option、Either 和 PartialFunction 的模拟存在(使用相关导入)
