[英]It looks like nSubsitute is just testing itself rather than my code
Possibly stupid question.可能是愚蠢的问题。 In the docs they give this example
在文档中他们给出了这个例子
calculator.Add(1, 2).Returns(3);
Assert.That(calculator.Add(1, 2), Is.EqualTo(3));
Am I testing that the actual calculator returns 3 or just that the substitute does?我是在测试实际计算器返回 3 还是只是替代计算器返回 3? If the latter, what is the point?
如果是后者,那意义何在?
I think that in the example on the front page ( https://nsubstitute.github.io/ ), they are just showing that it works, it is not part of your test really.我认为在首页 ( https://nsubstitute.github.io/ ) 的例子中,他们只是表明它有效,它并不是你测试的一部分。
I'm not sure where my brain went, but I seem to have momentarily lost the point of a mock.我不确定我的大脑去了哪里,但我似乎暂时失去了模拟的意义。 Saying
说
calculator.Add(1, 2).Returns(3)
is the wrong example.是错误的例子。 A much better example would be
一个更好的例子是
var person = database.GetMember(123) returns "Jesse Liberty"
not so that I can test the mock, but so that I can test code that depends on the database.不是为了测试模拟,而是为了测试依赖于数据库的代码。
Obvious, I know, but sometimes the brain just shuts down.很明显,我知道,但有时大脑会停止工作。
