我如何将数据驱动和预期异常归因于单元测试

Question

I have a unit test function, which attribute as 'datadriven'. it calls another function that expected to throw an exception. if i attribute the both first method or the twice with "ExpectedException" it fails, and doesn't continue with the other rows on the data source. what should I do?

Answer 1

You can use the Assert.Throws() method in NUnit to verify that a method within your test throws an exception.

Assert.Throws<FileNotFoundException>(() => ThisMethodThrowsFileNotFound());

The ExpectedException attribute is meant to be used on the test method (the one with the Test attribute). Decorating any other method with it has no effect.
