ScalaTest 抛出通过测试异常消息

Question

为了测试我的代码是否抛出预期的异常，我使用以下语法:

  an [IllegalArgumentException] should be thrownBy(Algorithms.create(degree))

有什么方法可以测试抛出的异常是否包含预期的消息，例如:

  an [IllegalArgumentException(expectedMessage)] should be thrownBy(Algorithms.create(degree)) -- what doesn't compile 

?

Answer 1

Documentation :

the [ArithmeticException] thrownBy 1 / 0 should have message "/ by zero"

并使用该示例:

 the [IllegalArgumentException] thrownBy(Algorithms.create(degree)) should have message expectedMessage
