  • Support for C# 7.2's in parameter modifier (@stakx, #624, #625)
  • Missing methods ReturnsAsync and ThrowsAsync for sequential setups of methods returning a ValueTask (@stakx, #626)

Changed

  • Breaking change: All ReturnsAsync and ThrowsAsync setup methods now consistently return a new Task on each invocation (@snrnats, #595)
  • Speed up Mock.Of<T>() by approx. one order of magnitude (@informatorius, #598)
  • Update package reference to Castle.Core (DynamicProxy) from version 4.2.1 to 4.3.0 (@stakx, #624)

Fixed

  • Returns regression with null function callback (@Caraul, #602)

4.8.2 (2018-02-23)

Changed

  • Upgraded System.ValueTuple dependency to version 4.4.0 in order to reestablish Moq compatibility with .NET 4.7 (and later), which already include the ValueTuple types (@stakx, #591)

Fixed

  • Wrong parameters count for extension methods in Callback and Returns (@Caraul, #575)
  • CallBase regression with members of additional interfaces (@stakx, #583)

Added

  • C# 7 tuple support for DefaultValue.Empty and DefaultValue.Mock (@stakx, #563)

Changed

  • Downgraded System.Threading.Tasks.Extensions and System.ValueTuple dependencies to versions 4.3.0 as suggested by @tothdavid in order to improve Moq compatibility with .NET 4.6.1 / help prevent MissingMethodException and similar (@stakx, #571)

Fixed

  • CallBase regression with explicitly implemented interface methods (@stakx, #558)

4.8.0 (2017-12-24)

Same as 4.8.0-rc1 (see below), plus some significant speed improvements.

Changed

  • SetupAllProperties now fully supports property type recursion / loops in the object graph, thanks to deferred property initialization (@stakx, #550)

4.8.0-rc1 (2017-12-08)

This is a pre-release version.

Added

  • Support for sequential setup of void methods (@alexbestul, #463)
  • Support for sequential setups (SetupSequence) of protected members (@stakx, #493)
  • Support for callbacks for methods having ref or out parameters via two new overloads of Callback and Returns (@stakx, #468)
  • Improved support for setting up and verifying protected members (including generic methods and methods having by-ref parameters) via the new duck-typing mock.Protected().As<TAnalog>() interface (@stakx, #495, #501)
  • Support for ValueTask<TResult> when using the ReturnsAsync extension methods, similar to Task<TResult> (@AdamDotNet, #506)
  • Special handling for ValueTask<TResult> with DefaultValue.Empty (@stakx, #529)
  • Support for custom default value generation strategies besides DefaultValue.Empty and DefaultValue.Mock: Implement custom providers by subclassing either DefaultValueProvider or LookupOrFallbackDefaultValueProvider, install them by setting Mock[Repository].DefaultValueProvider (@stakx, #533, #536)
  • Allow DefaultValue.Mock to mock Task<TMockable> and ValueTask<TMockable> (@stakx, #502)
  • Match any value for ref parameters with It.Ref<T>.IsAny (or ItExpr.Ref<T>.IsAny for protected methods) as you would with It.IsAny<T>() for regular parameters (@stakx, #537)
  • Mock.VerifyNoOtherCalls() to check whether all expected invocations have been verified -- can be used as an alternative to MockBehavior.Strict (@stakx, #539)

Changed

  • Breaking change: SetupSequence now overrides pre-existing setups like all other Setup methods do. This means that exhausted sequences no longer fall back to previous setups to produce a "default" action or return value. (@stakx, #476)
  • Delegates passed to Returns are validated a little more strictly than before (return type and parameter count must match with method being set up) (@stakx, #520)
  • Change assembly versioning scheme to major.minor.0.0 to help prevent assembly version conflicts and to reduce the need for binding redirects (@stakx, #554)

Fixed

  • Update a method's invocation count correctly, even when it is set up to throw an exception (@stakx, #473)
  • Sequences set up with SetupSequence are now thread-safe (@stakx, #476)
  • Record calls to methods that are named like event accessors (add_X, remove_X) so they can be verified (@stakx, #488)

  • Let SetupAllProperties skip inaccessible methods (@stakx, #499)
  • Prevent Moq from relying on a mock's implementation of IEnumerable<T> (@stakx, #510)

  • Custom matcher properties not printed correctly in error messages (@stakx, #517)
  • Infinite loop when invoking delegate in Mock.Of setup expression (@stakx, #528)

Obsoleted

  • [Matcher] has been deprecated in favor of Match.Create (@stakx, #514)

4.7.145 (2017-11-06)

Changed

  • Moq no longer collects source file information for verification error messages by default. A current .NET Framework regression (microsoft/dotnet#529) makes this extremely costly, so this is now an opt-in feature; see Switches.CollectSourceFileInfoForSetups (@stakx, #515)

Added

  • Mock.Switches and MockRepository.Switches, which allow opting in and out of certain features (@stakx, #515)

4.7.142 (2017-10-11)

Changed

  • Update package reference to Castle.Core (DynamicProxy) from version 4.2.0 to 4.2.1 due to a regression; see castleproject/Core#309 for details (@stakx, #482)

Fixed

  • TypeLoadExceptions ("Method does not have an implementation") caused by the regression above, see e.g. #469 (@stakx, #482)

4.7.137 (2017-09-30)

Changed

  • Update package reference to Castle.Core (DynamicProxy) from version 4.1.1 to 4.2.0, which uses a new assembly versioning scheme that should eventually reduce assembly version conflicts and the need for assembly binding redirects (@stakx, #459)

Fixed

  • mock.Object should always return the exact same proxy object, regardless of whether the mock has been cast to an interface via .As<T>() or not (@stakx, #460)

4.7.127 (2017-09-26)

Changed

  • Make setups for inaccessible internal members fail fast by throwing an exception (@stakx, #455)

Removed

  • The redundant type ObsoleteMockException has been removed (@stakx)

Fixed

  • Make SetupAllProperties work correctly for same-typed sibling properties (@stakx, #442)
  • Switch back from portable PDBs to classic PDBs for better compatibility of SourceLink with older .NET tools (@stakx, #443)
  • Make strict mocks recognize that .CallBase() can set up a return value, too (@stakx, #450)

4.7.99 (2017-07-17)

Added

  • Add [NeutralResourcesLanguage] to assembly info for portable library use (@benbillbob, #394)
  • Add portable, SourceLink-ed debugging symbols (PDB) to NuGet package, enabling end users to step into Moq's source code (@stakx, #417)

  • Allow setting up null return values using Mock.Of (@stakx, #396)
  • Allow Mock<T>.Raise to raise events on child mocks instead of raising no or the wrong event (@stakx, #397)
  • Improve specificity of Setup / Verify exception messages for static members and extension methods (@stakx, #400)
  • Prevent internal interception on a mock from changing its DefaultValue property (@vladonemo, #411)
  • Prevent stack overflow in conditional setups (@stakx, #412)
  • Fix NullReferenceException caused by internally relying on a mock's IEnumerable implementation (@stakx, #413)
  • Improve method match accuracy in ExtractProxyCall so that the order of setting up methods in an hierarchy of interfaces does not matter (@stakx, #415)
  • Improve mockability of C++/CLI interfaces having custom modifiers (modopt, modreq) in their method signatures (@stakx, #416)
  • Make types implementing the same generic type more than two times mockable (@stakx, #416)

3.0

  • Silverlight support! Finally integrated Jason's Silverlight contribution! Issue #73
  • Brand-new simplified event raising syntax (#130): mock.Raise(foo => foo.MyEvent += null, new MyArgs(...));
  • Support for custom event signatures (not compatible with EventHandler): mock.Raise(foo => foo.MyEvent += null, arg1, arg2, arg3);
  • Substantially improved property setter behavior: mock.VerifySet(foo => foo.Value = "foo"); (also available for SetupSet
  • Renamed Expect* with Setup*
  • Vastly simplified custom argument matchers: public int IsOdd() { return Match<int>.Create(v => i % 2 == 0); }
  • Added support for verifying how many times a member was invoked: mock.Verify(foo => foo.Do(), Times.Never());
  • Added simple sample app named StoreSample
  • Moved Stub functionality to the core API (SetupProperty and SetupAllProperties)
  • Fixed sample ASP.NET MVC app to work with latest version
  • Allow custom matchers to be created with a substantially simpler API
  • Fixed issue #145 which prevented discrimination of setups by generic method argument types
  • Fixed issue #141 which prevented ref arguments matching value types (i.e. a Guid)
  • Implemented improvement #131: Add support for It.IsAny and custom argument matchers for SetupSet/VerifySet
  • Implemented improvement #124 to render better error messages
  • Applied patch from David Kirkland for improvement #125 to improve matching of enumerable parameters
  • Implemented improvement #122 to provide custom errors for Verify
  • Implemented improvement #121 to provide null as default value for Nullable<T>
  • Fixed issue #112 which fixes passing a null argument to a mock constructor
  • Implemented improvement #111 to better support params arguments
  • Fixed bug #105 about improperly overwriting setups for property getter and setter
  • Applied patch from Ihar.Bury for issue #99 related to protected expectations
  • Fixed issue #97 on not being able to use SetupSet/VerifySet if property did not have a getter
  • Better integration with Pex (http://research.microsoft.com/en-us/projects/Pex/)
  • Various other minor fixes (#134, #135, #137, #138, #140, etc.)

2.6

  • Implemented Issue #55: We now provide a mock.DefaultValue = [DefaultValue.Empty | DefaultValue.Mock] which will provide the current behavior (default) or mocks for mockeable return types for loose mock invocations without expectations.
  • Added support for stubbing properties from moq-contrib: now you can do mock.Stub(m => m.Value) and add stub behavior to the property. mock.StubAll() is also provided. This integrates with the DefaultValue behavior too, so you can stub entire hierarchies :).
  • Added support for mocking methods with out and ref parameters (Issue #50)
  • Applied patch contributed by slava for Issue #72: add support to limit numbor of calls on mocked method (we now have mock.Expect(...).AtMost(5))
  • Implemented Issue #94: Easier setter verification: Now we support ExpectSet(m = m.Value, "foo") and VerifySet(m = m.Value, 5) (Thanks ASP.NET MVC Team!)
  • Implemented issue #96: Automatically chain mocks when setting expectations. It's now possible to specify expectations for an entire hierarchy of objects just starting from the root mock. THIS IS REALLY COOL!!!
  • Fixed Issue #89: Expects() does not always return last expectation
  • Implemented Issue 91: Expect a method/property to never be called (added Never() method to an expectation. Can be used on methods, property getters and setters)
  • Fixed Issue 86: IsAny<T> should check if the value is actually of type T
  • Fixed Issue 88: Cannot mock protected internal virtual methods using Moq.Protected
  • Fixed Issue 90: Removing event handlers from mocked objects
  • Updated demo and added one more test for the dynamic addition of interfaces

2.5

  • Added support for mocking protected members
  • Added new way of extending argument matchers which is now very straightforward
  • Added support for mocking events
  • Added support for firing events from expectations
  • Removed usage of MBROs which caused inconsistencies in mocking features
  • Added ExpectGet and ExpectSet to better support properties, and provide better intellisense.
  • Added verification with expressions, which better supports Arrange-Act-Assert testing model (can do Verify(m => m.Do(...)))
  • Added Throws<TException>
  • Added mock.CallBase property to specify whether the virtual members base implementation should be called
  • Added support for implementing and setting expectations and verifying additional interfaces in the mock, via the new mock.As<TInterface>() method (thanks Fernando Simonazzi!)
  • Improved argument type matching for Is/IsAny (thanks Jeremy.Skinner!)

2.0

  • Refactored fluent API on mocks. This may cause some existing tests to fail, but the fix is trivial (just reorder the calls to Callback, Returns and Verifiable)
  • Added support for retrieving a Mock<T> from a T instance created by a mock.
  • Added support for retrieving the invocation arguments from a Callback or Returns.
  • Implemented AtMostOnce() constraint
  • Added support for creating MBROs with protected constructors
  • Loose mocks now return default empty arrays and IEnumerables instead of nulls

1.5.1

  • Refactored MockFactory to make it simpler and more explicit to use with regards to verification. Thanks Garry Shutler for the feedback!

1.5

  • Added MockFactory to allow easy construction of multiple mocks with the same behavior and verification

1.4

  • Added support for passing constructor arguments for mocked classes.
  • Improved code documentation

1.3

  • Added support for overriding expectations set previously on a Mock. Now adding a second expectation for the same method/property call will override the existing one. This facilitates setting up default expectations in a fixture setup and overriding when necessary in a specific test.
  • Added support for mock verification. Both Verify and VerifyAll are provided for more flexibility (the former only verifies methods marked Verifiable)

1.2

  • Added support for MockBehavior mock constructor argument to affect the way the mocks expect or throw on calls.

1.1

  • Merged branch for dynamic types. Now Moq is based on Castle DynamicProxy2 to support a wider range of mock targets.
  • Added ILMerge so that Castle libraries are merged into Moq assembly (no need for external references and avoid conflicts)

1.0

  • Initial release, initial documentation process in place, etc.
