QUESTION
I have the following classes:
...ANSWER
Answered 2021-Oct-10 at 21:46The original design of AutoBogus was to generate small object graphs for unit tests. Generating the numbers you require could have a performance impact. However, if the above is what you are trying to generate and nothing more complex, then it could be small enough to succeed.
To use AutoBogus out the box you can do the following:
QUESTION
Why does calling fake.Provide()
wipe out fakes already configured with A.CallTo()
? Is this a bug?
I'm trying to understand a problem I've run into with Autofac.Extras.FakeItEasy (aka AutoFake). I have a partial solution, but I don't understand why my original code doesn't work. The original code is complicated, so I've spent some time simplifying it for the purposes of this question.
Why does this test fail? (working DotNetFiddle)
...ANSWER
Answered 2021-Jun-12 at 02:41It isn't that the Fake's configuration is being changed. In the first test, Resolve
is returning different Fakes each time it's called. (Check them for reference equality; I did.)
Provide
creates a new scope and pushes it on a stack. The topmost scope is used by Resolve
when it finds an object to return. I think this is why you're getting different Fakes in ACallTo_before_Provide
.
Is this a bug? Or is this the expected behavior? If this is the expected behavior, can someone explain why it works like this?
It's not clear to me. I'm not an Autofac user, and don't understand why an additional scope is introduced by Provide
. The stacked scope behaviour was introduced in PR 18. Perhaps the author can explain why.
In the meantime, if possible, I'd Provide
all you need to before Resolve
ing, if you can manage it.
QUESTION
A colleague of mine needed to test whether some F# functions are called or not a given number of times.
In Moq, you can usually do that if you have a class with virtual members or an interface (unless if this has changed, but it doesn't seem to be the case), but afaik you can hardly mock static methods with Moq for example, which in most cases is how F# functions are compiled to, at least from an IL standpoint. Or, would require to use another library to do so like AutoFake or Pose and I'm not sure the F# support is actually properly implemented.
We ended up creating a CallCounter
type, which would hold the function to invoke and a variable counting the number of times this function has been invoked (a bit similar to this answer but with an actual type).
ANSWER
Answered 2020-Jun-20 at 03:50Unless I'm missing something, I don't see why you need any objects or interfaces. Since it's all just functions, you could make funDep
just increment a locally declared mutable counter as a side effect:
