So we can do: instead of We can even use this to setup multiple properties: This one can help make tests easier to follow … consistency of Moq's API overall, even given the breaking change. While I can see how changing that behavior could be a breaking change, I've Moq verify async method called. *** wrote: Sign in I wrote this because there is little to no information on how to combine ASP.NET Core with Moq in integration tests. Sie können Beispiele bewerten, um die Qualität der Beispiele zu verbessern. Verifiable is straight forward. Think about it: AnyType is a type placeholder. ). I was quite excited to finally be able to get the feature out there so that people can start using it. very large number of invocations on your mock, these get recorded It is now the Internal type FormattedLogValues. Successfully merging a pull request may close this issue. That seems to make an unnecessarily resource Thank you again for considering the change. new mock for every test. Here is my code for get a formatted message I can assert on if it helps: Here's my attempt of some functions that enable logged object and logged message and logged exception verification by type. It.IsAnyType?, It.IsAnyType[], It.IsAnyType[,], IEnumerable, ref/in/out It.IsAnyType, etc. That makes sense. On Thu, Jan 3, 2019, 9:55 AM stakx ***@***. By clicking “Sign up for GitHub”, you agree to our terms of service and At the time of the mock setup there might be different situations which we need to implement during unit test configuration. At first, give the reference of Moq framework to your application. I suspect that being able to remove invocation records was a cheap (if Has anyone figured out the CallBack magic syntax yet? I'm planning to add support for that kind of thing eventually; for the moment, there's a fairly easy workaround: The important bit (for now) is that It.IsAnyType is not used in a nested position in the It.IsAny<> type argument. _loggerMock.Verify(l => l.Log(LogLevel.Error, It.IsAny(), It.Is((object v, Type _) => true), null, It.IsAny>())); Getting "Expected invocation on the mock at least once, but was never performed: l => l.Log(LogLevel.Error, It.IsAny(), It.Is((v, _) => True), null, It.IsAny>()))", The problem is with the "Func<>". If they were matched against setups at the time of the VerifyAll call, the first setup (for the child playing with a red toy) would fail. What Verify and VerifyAll do is to check whether all setups have been invoked at least once. However, I did try the workaround suggested in there and I still can't get it to work. Setting up moq and verifying that a method was called. (If it's decided that this feature should be implemented, I'm happy to offer some guidance, if desired.) I am trying to use Moq to verify the correct number of records is returned from my code, have the following but returns 0 as sending a different parameter, parameter passed is DefinedOnly as a boolean value. Calling Verify() should only apply to setups made using Verifiable(). — That is not currently the case... but I'm planning to implement this kind of "type erasure" in the next iteration. # Creating our first Mock. I believe that the ability to clear the set of recorded invocations was I tried to use it like this; Strangly it works in .NET Core 2.2 but is still failing in .NET Core 3.0 Preview 8. (They only differ in which setups they look at, but that's irrelevant for this issue. privacy statement. does not seem to work, I get the following: It is impossible to call the provided strongly-typed predicate due to the use of a type matcher. I tried a couple of variations in the Callback signature: Edit: I tried using the InvocationAction and that way the Callback is correctly invoked: I'm still not able to use the formatter parameter int the Log function because of the internal struct but I can use the rest of the parameters. I have created a package to deal with verifying the ILogger calls just like you would expect to do it using Moq. current functionality. [...] and then Invocations.Clear() is called on the Mock object, it does I'm trying to setup a callback and it's not working. I've trouble understanding the use case that would benefit from the Dies sind die am besten bewerteten C# (CSharp) Beispiele für die Moq.Moq.Mock.Verify, die aus Open Source-Projekten extrahiert wurden. or an overload to clear the invocation count in addition to/instead of what Namespace: Moq Assembly: Moq (in Moq.dll) Version: 4.0.10827.0 (4.0.0.0) Syntax. I'm going to close this issue since this problem has been solved. I would expect the code to throw an error on the call to an error. You can also verify that the methods you set up are being called in the tested code. One method of the mocked interface implementation is accepting a parameter of type Expression< Check calls Received() for async method. @granadacoder You will have to cast but ILogger only have one method for logging, there is no overloads to take into account. For now, we're going the opposite direction and try to make type matcher discovery as fast as possible. while VerifyAll() applies to all setups, and VerifyNoOtherCalls() applies to anything that was not otherwise verified. Implementation should be perfectly feasible, and probably even fairly easy. somewhat inelegant) way around that problem for someone in the past.

Your suggestion It.Is((object v, Type _) => v.ToString().Contains(message)) Not quite. @jchesshir - I've been expecting this issue to be raised eventually, thanks for reporting it. When you have a test that requires a very large number of invocations on your mock, these get recorded (regardless of whether your test actually requires that for later assertions or not), and that can eventually cause a OutOfMemoryException. Already on GitHub? But I suppose we could spend some more time on documentation. If an expected function on a Mock is called and then Invocations.Clear() is called on the Mock object, it does not erase the record of the call. This ensures that the flow of the program is as expected. Consider this example: This only works because invocations are matched against the setups at the time of the invocation. Working Examples. The idea is to create a concrete implementation of an interface and control how certain methods on that interface responds when called. it some more thought. assertions or not), and that can eventually cause a OutOfMemoryException. This problem is solved only if we translate the expressions like logger => logger.LogInformation("Processed { Latitude = 25, Longitude = 134 } in 034 ms.") into ones expected by logger.Log. However, there are reasons why VerifyAll works the way it does:. The new generic type argument matcher support in Moq is new, and one thing I decided to leave out for the first version (for performance reasons) is support for such "composite" / "nested" types. In this example we will understand a few of the important setups of Moq framework. ***> wrote: I've trouble understanding the use case that would benefit from the current functionality. That being said, I'll still look into the request you've made as it still seems like a sensible change. SetupSet helps us set expectation for our setters, that is we expect our setter to be set with specific value. Moq VerifyGet. You'd no longer be able to do certain things. Moq: Mock..::.. Verify Method : Mock Class Example See Also Send Feedback: Verifies that all verifiable expectations have been met. We also didn’t want to make this functionality too … As it stands I have to create and initialize a new mock for every test. works great though, thanks. privacy statement. You signed in with another tab or window. I'd like to be able to reuse the mock Consequently, a call to a Verify function after the call to Invocations.Clear succeeds. How do I verify mocked async method called with correct expression , I have written some tests using XUnit and Moq. The problem with the first stance (i.e. In the example at the top, VerifyNoOtherCalls should not have thrown an exception because a call was setup, made, and verified. I think what you're requesting might actually improve the logical consistency of Moq's API overall, even given the breaking change. For example: The text was updated successfully, but these errors were encountered: @jchesshir - I've been expecting this issue to be raised eventually, thanks for reporting it. bloated test set.
