FakeItEasy “参数”论点
我有一个带有以下签名的方法。
Foo GetFooById( int id, params string[] children )
该方法是在名为 IDal 的接口上定义的。
在我的单元测试中，我编写了以下内容：
IDal dal = A.Fake<IDal>();
Foo fooToReturn = new Foo();
fooToReturn.Id = 7;
A.CallTo(()=>dal.GetFooById(7, "SomeChild")).Returns(fooToReturn);
当测试运行时，第二个参数的签名不匹配。我尝试将其更改为：
A.CallTo(()=>dal.GetFooById(7, new string[]{"SomeChild"})).Returns(fooToReturn);
但这也不成功。我可以让它工作的唯一方法是使用：
A.CallTo(()=>dal.GetFooById(7, A<string[]>.Ignored )).Returns(fooToReturn);
我希望能够指定第二个参数的值，这样如果有人更改它，单元测试就会中断。
I have a method with the following signature.
Foo GetFooById( int id, params string[] children )
This method is defined on an interface named IDal.
In my unit test I write the following:
IDal dal = A.Fake<IDal>();
Foo fooToReturn = new Foo();
fooToReturn.Id = 7;
A.CallTo(()=>dal.GetFooById(7, "SomeChild")).Returns(fooToReturn);
When the test runs, the signature isn't being matched on the second argument. I tried changing it to:
A.CallTo(()=>dal.GetFooById(7, new string[]{"SomeChild"})).Returns(fooToReturn);
But that was also unsuccessful. The only way I can get this to work is to use:
A.CallTo(()=>dal.GetFooById(7, A<string[]>.Ignored )).Returns(fooToReturn);
I'd prefer to be able to specify the value of the second argument so the unit test will break if someone changes it.

更新：我不确定什么时候，但问题早已得到解决。 FakeItEasy 2.0.0 支持开箱即用的所需行为。
在解析调用规范时可能会出现特殊情况的参数数组。请在以下位置提交问题：https:// github.com/patrik-hagne/FakeItEasy/issues?sort=created&direction=desc&state=open
在那之前，最好的解决方法是 这：
Update: I'm not sure when, but the issue has long since been resolved. FakeItEasy 2.0.0 supports the desired behaviour out of the box.
It might be possible to special case param-arrays in the parsing of the call-specification. Please submit an issue at: https://github.com/patrik-hagne/FakeItEasy/issues?sort=created&direction=desc&state=open
Until then, the best workaround is this:
