4.18.0

New major version of DynamicProxy (you may get better performance!), so please update with care.

Changed

• Update package reference to Castle.Core (DynamicProxy) from version 4.4.1 to 5.0.0 (@stakx, #1257)
• Adjusted our target frameworks to match DynamicProxy's (see their discussion about which frameworks to target):
  • minimum .NET Framework version raised from net45 to net462
  • additional net6.0 TFM

Fixed

• Can't set up "private protected" properties (@RobSiklos, #1170)
• Using [...] an old version of System.Net.Http which is vulnerable to "DoS", "Spoofing", "Privilege Escalation", "Authentication Bypass" and "Information Exposure" (@sidseter, #1219)
• Failure when invoking a method with by-ref parameter & mockable return type on a mock with CallBase and DefaultValue.Mock configured (@IanKemp, #1249)

4.17.2

Fixed

• Regression: Property stubs not working on sub mock (@aaronburro, #1240)

4.17.1

Added

• SetupSet, VerifySet methods for mock.Protected().As<>() (@tonyhallett, #1165)
• New Throws method overloads that allow specifying a function with or without parameters, to provide an exception, for example .Throws(() => new InvalidOperationException())
  and Setup(x => x.GetFooAsync(It.IsAny<string>()).Result).Throws((string s) => new InvalidOperationException(s)). (@adam-knights, #1191)

Changed

• Update package reference to Castle.Core (DynamicProxy) from version 4.4.0 to 4.4.1 (@stakx, #1233)

Fixed

• The guard against unmatchable matchers (added in #900) was too strict; relaxed it to enable an alternative user-code shorthand _ for It.IsAny<>() (@adamfk, #1199)
• mock.Protected() setup methods fail when argument is of type Expression (@tonyhallett, #1189)
• Parameter is invalid in Protected().SetupSet() ... VerifySet (@tonyhallett, #1186)
• Virtual properties and automocking not working for mock.Protected().As<>() (@tonyhallett, #1185)
• Issue mocking VB.NET class with overloaded property/indexer in base class (@myurashchyk, #1153)
• Equivalent arrays don't test equal when returned from a method, making Verify fail when it should not (@evilc0, #1225)
• Property setups are ignored on mocks instantiated using Mock.Of (@stakx, #1066)
• SetupAllProperties causes mocks to become race-prone (@estrizhok, #1231)

4.16.1

Added

• CallBase can now be used with interface methods that have a default interface implementation. It will call the most specific override. (@stakx, #1130)

Changed

• Improved error message formatting of It.Is lambda expressions that capture local variables. (@bfriesen, #1140)

Fixed

• AmbiguousMatchException raised when interface has property indexer besides property in VB. (@mujdatdinc, #1129)
• Interface default methods are ignored (@hahn-kev, #972)
• Callback validation too strict when setting up a task's .Result property (@stakx, #1132)
• setup.Returns(InvocationFunc) wraps thrown exceptions in TargetInvocationException (@stakx, #1141)

4.16.0

Added

• Ability to directly set up the .Result of tasks and value tasks, which makes setup expressions more uniform by rendering dedicated async verbs like .ReturnsAsync, .ThrowsAsync, etc. unnecessary:

  -mock.Setup(x => x.GetFooAsync()).ReturnsAsync(foo)
  +mock.Setup(x => x.GetFooAsync().Result).Returns(foo)

  This is useful in places where there currently aren't any such async verbs at all:

  -Mock.Of<X>(x => x.GetFooAsync() == Task.FromResult(foo))
  +Mock.Of<X>(x => x.GetFooAsync().Result == foo)

  This also allows recursive setups / method chaining across async calls inside a single setup expression:

  -mock.Setup(x => x.GetFooAsync()).ReturnsAsync(Mock.Of<IFoo>(f => f.Bar == bar))
  +mock.Setup(x => x.GetFooAsync().Result.Bar).Returns(bar)

  or, with only Mock.Of:

  -Mock.Of<X>(x => x.GetFooAsync() == Task.FromResult(Mock.Of<IFoo>(f => f.Bar == bar)))
  +Mock.Of<X>(x => x.GetFooAsync().Result.Bar == bar)

  This should work in all principal setup methods (Mock.Of, mock.Setup…, mock.Verify…). Support in mock.Protected() and for custom awaitable types may be added in the future. (@stakx, #1126)

Changed

• Attempts to mark conditionals setup as verifiable are once again allowed; it turns out that forbidding it (as was done in #997 for version 4.14.0) is in fact a regression. (@stakx, #1121)

Fixed

• Performance regression: Adding setups to a mock becomes slower with each setup (@CeesKaas, #1110)

• Regression: mock.Verify[All] no longer marks invocations as verified if they were matched by conditional setups. (@Lyra2108, #1114)

4.15.2

Changed

• Upgraded System.Threading.Tasks.Extensions dependency to version 4.5.4 (@JeffAshton, #1108)

4.15.1

Added

• New method overloads for It.Is, It.IsIn, and It.IsNotIn that compare values using a custom IEqualityComparer<T> (@weitzhandler, #1064)
• New properties ReturnValue and Exception on IInvocation to query recorded invocations return values or exceptions (@MaStr11, #921, #1077)
• Support for "nested" type matchers, i.e. type matchers that appear as part of a composite type (such as It.IsAnyType[] or Func<It.IsAnyType, bool>). Argument match expressions like It.IsAny<Func<It.IsAnyType, bool>>() should now work as expected, whereas they previously didn't. In this particular example, you should no longer need a workaround like (Func<It.IsAnyType, bool>)It.IsAny<object>() as originally suggested in #918. (@stakx, #1092)

Changed

• Event accessor calls (+= and -=) now get consistently recorded in Mock.Invocations. This previously wasn't the case for backwards compatibility with VerifyNoOtherCalls (which got implemented before it was possible to check them using Verify{Add,Remove}). You now need to explicitly verify expected calls to event accessors prior to VerifyNoOtherCalls. Verification of += and -= now works regardless of whether or not you set those up (which makes it consistent with how verification usually works). (@80O, @stakx, #1058, #1084)
• Portable PDB (debugging symbols) are now embedded in the main library instead of being published as a separate NuGet symbols package (`.snupkg) (@kzu, #1098)

Fixed

• SetupProperty fails if property getter and setter are not both defined in mocked type (@stakx, #1017)
• Expression tree argument not matched when it contains a captured variable – evaluate all captures to their current values when comparing two expression trees (@QTom01, #1054)
• Failure when parameterized Mock.Of<> is used in query comprehension from clause (@stakx, #982)

4.14.7

Changed

• Mocks created by DefaultValue.Mock now inherit SetupAllProperties from their "parent" mock (like it says in the XML documentation) (@stakx, #1074)

Fixed

• Setup not triggered due to VB.NET transparently inserting superfluous type conversions into a setup expression (@InteXX, #1067)
• Nested mocks created by Mock.Of<T>() no longer have their properties stubbed since version 4.14.0 (@vruss, @1071)
• Verify fails for recursive setups not explicitly marked as Verifiable (@killergege, #1073)
• Mock.Of<> fails for COM interop types that are annotated with a [CompilerGenerated] custom attribute (@killergege, #1072)
