ScalaTest thrownBy测试异常消息
要测试我的代码是否引发预期的异常,我使用以下语法:ScalaTest thrownBy测试异常消息,scala,scalatest,Scala,Scalatest,要测试我的代码是否引发预期的异常,我使用以下语法: an [IllegalArgumentException] should be thrownBy(Algorithms.create(degree)) 是否有任何方法可以测试抛出的异常是否包含以下预期消息: an [IllegalArgumentException(expectedMessage)] should be thrownBy(Algorithms.create(degree)) -- what doesn't compil
an [IllegalArgumentException] should be thrownBy(Algorithms.create(degree))
是否有任何方法可以测试抛出的异常是否包含以下预期消息:
an [IllegalArgumentException(expectedMessage)] should be thrownBy(Algorithms.create(degree)) -- what doesn't compile
?:
举个例子:
the [IllegalArgumentException] thrownBy(Algorithms.create(degree)) should have message expectedMessage
检查消息的语法错误。作为bjfletcher建议的替代方案,您还可以根据文档使用以下内容:
val-thrownBy-Algorithms.create(degree)
thrownBy.getMessage应等于(“我如何检查消息的子字符串?将“thrownBy…”的结果分配给val,然后使用常规匹配器?如果要在子字符串上断言,可以:([ArrithmeticException]thrownBy 1/0)。getMessage应包括(“零”)
the [IllegalArgumentException] thrownBy(Algorithms.create(degree)) should have message expectedMessage
