如何在 Specs2 (Scala) 中显示自定义失败消息? [英] How to show custom failure message in Specs2 (Scala)?

问题描述

例如，对于这样的代码:

For example, for code like this:

Is there an elegant way to get customised message displayed here?

推荐答案

首先，您可以命名要测试的值.

First you can name value you're testing.

myNum aka "meaningful name" must_== expectedValue

您也可以覆盖完整的消息.

You can also overwrite the full message.

(myNum must_== expectedValue).setMessage("Full failure message")
