Implements the fluent API.

The expectation will be considered only in the former condition.

Setups the get.

The type of the property. The expression.

Setups the set.

The type of the property. The setter expression.

Defines the Callback verb and overloads.

Helper interface used to hide the base members from the fluent API to make it much cleaner in Visual Studio intellisense.

Specifies a callback to invoke when the method is called.

The callback method to invoke. The following example specifies a callback to set a boolean value that can be used later:


            var called = false;
            mock.Setup(x => x.Execute())
                .Callback(() => called = true);

Specifies a callback to invoke when the method is called that receives the original arguments.

Language for ReturnSequence

Returns value

Throws an exception

The first method call or member access will be the last segment of the expression (depth-first traversal), which is the one we have to Setup rather than FluentMock. And the last one is the one we have to Mock.Get rather than FluentMock.

Base class for mocks and static helper class with methods that apply to mocked objects, such as to retrieve a from an object instance.

Creates an mock object of the indicated type.

The type of the mocked object. The mocked object created.

Creates an mock object of the indicated type.

The predicate with the specification of how the mocked object should behave. The type of the mocked object. The mocked object created.

Initializes a new instance of the class.

Retrieves the mock object for the given object instance.

Type of the mock to retrieve. Can be omitted as it's inferred from the object instance passed in as the instance. The instance of the mocked object.The mock associated with the mocked object. The received instance was not created by Moq. The following example shows how to add a new setup to an object instance which is not the original but rather the object associated with it:


				// Typed instance, not the mock, is retrieved from some test API.
				HttpContextBase context = GetMockContext();

				// context.Request is the typed object from the "real" API
				// so in order to add a setup to it, we need to get
				// the mock that "owns" it
				Mock<HttpRequestBase> request = Mock.Get(context.Request);
				mock.Setup(req => req.AppRelativeCurrentExecutionFilePath)
					 .Returns(tempUrl);

Returns the mocked object value.

Verifies that all verifiable expectations have been met.

This example sets up an expectation and marks it as verifiable. After the mock is used, a Verify() call is issued on the mock to ensure the method in the setup was invoked:


				var mock = new Mock<IWarehouse>();
				this.Setup(x => x.HasInventory(TALISKER, 50)).Verifiable().Returns(true);
				...
				// other test code
				...
				// Will throw if the test code has didn't call HasInventory.
				this.Verify();

Not all verifiable expectations were met.

Verifies all expectations regardless of whether they have been flagged as verifiable.

This example sets up an expectation without marking it as verifiable. After the mock is used, a call is issued on the mock to ensure that all expectations are met:


				var mock = new Mock<IWarehouse>();
				this.Setup(x => x.HasInventory(TALISKER, 50)).Returns(true);
				...
				// other test code
				...
				// Will throw if the test code has didn't call HasInventory, even
				// that expectation was not marked as verifiable.
				this.VerifyAll();

At least one expectation was not met.

Gets the interceptor target for the given expression and root mock, building the intermediate hierarchy of mock objects if necessary.

Raises the associated event with the given event argument data.

Adds an interface implementation to the mock, allowing setups to be specified for it.

This method can only be called before the first use of the mock property, at which point the runtime type has already been generated and no more interfaces can be added to it. Also, must be an interface and not a class, which must be specified when creating the mock instead. The mock type has already been generated by accessing the property. The specified is not an interface. The following example creates a mock for the main interface and later adds to it to verify it's called by the consumer code:


				var mock = new Mock<IProcessor>();
				mock.Setup(x => x.Execute("ping"));

				// add IDisposable interface
				var disposable = mock.As<IDisposable>();
				disposable.Setup(d => d.Dispose()).Verifiable();

Type of interface to cast the mock to.

Behavior of the mock, according to the value set in the constructor.

Whether the base member virtual implementation will be called for mocked classes if no setup is matched. Defaults to .

Specifies the behavior to use when returning default values for unexpected invocations on loose mocks.

Gets the mocked object instance.

Retrieves the type of the mocked object, its generic type argument. This is used in the auto-mocking of hierarchy access.

Specifies the class that will determine the default value to return when invocations are made that have no setups and need to return a default value (for loose mocks).

Exposes the list of extra interfaces implemented by the mock.

Utility repository class to use to construct multiple mocks when consistent verification is desired for all of them.

If multiple mocks will be created during a test, passing the desired (if different than the or the one passed to the repository constructor) and later verifying each mock can become repetitive and tedious. This repository class helps in that scenario by providing a simplified creation of multiple mocks with a default (unless overriden by calling ) and posterior verification. The following is a straightforward example on how to create and automatically verify strict mocks using a :


            var repository = new MockRepository(MockBehavior.Strict);
            
            var foo = repository.Create<IFoo>();
            var bar = repository.Create<IBar>();
            
            // no need to call Verifiable() on the setup 
            // as we'll be validating all of them anyway.
            foo.Setup(f => f.Do());
            bar.Setup(b => b.Redo());
            
            // exercise the mocks here
            
            repository.VerifyAll(); 
            // At this point all setups are already checked 
            // and an optional MockException might be thrown. 
            // Note also that because the mocks are strict, any invocation 
            // that doesn't have a matching setup will also throw a MockException.

The following examples shows how to setup the repository to create loose mocks and later verify only verifiable setups:


            var repository = new MockRepository(MockBehavior.Loose);
            
            var foo = repository.Create<IFoo>();
            var bar = repository.Create<IBar>();
            
            // this setup will be verified when we verify the repository
            foo.Setup(f => f.Do()).Verifiable();
            	
            // this setup will NOT be verified 
            foo.Setup(f => f.Calculate());
            	
            // this setup will be verified when we verify the repository
            bar.Setup(b => b.Redo()).Verifiable();
            
            // exercise the mocks here
            // note that because the mocks are Loose, members 
            // called in the interfaces for which no matching
            // setups exist will NOT throw exceptions, 
            // and will rather return default values.
            
            repository.Verify();
            // At this point verifiable setups are already checked 
            // and an optional MockException might be thrown.

The following examples shows how to setup the repository with a default strict behavior, overriding that default for a specific mock:


            var repository = new MockRepository(MockBehavior.Strict);
            
            // this particular one we want loose
            var foo = repository.Create<IFoo>(MockBehavior.Loose);
            var bar = repository.Create<IBar>();
            
            // specify setups
            
            // exercise the mocks here
            
            repository.Verify();

Utility factory class to use to construct multiple mocks when consistent verification is desired for all of them.

If multiple mocks will be created during a test, passing the desired (if different than the or the one passed to the factory constructor) and later verifying each mock can become repetitive and tedious. This factory class helps in that scenario by providing a simplified creation of multiple mocks with a default (unless overriden by calling ) and posterior verification. The following is a straightforward example on how to create and automatically verify strict mocks using a :


            var factory = new MockFactory(MockBehavior.Strict);
            
            var foo = factory.Create<IFoo>();
            var bar = factory.Create<IBar>();
            
            // no need to call Verifiable() on the setup

            foo.Setup(f => f.Do());
            bar.Setup(b => b.Redo());
            
            // exercise the mocks here
            
            factory.VerifyAll(); 
            // At this point all setups are already checked

            foo.Setup(f => f.Calculate());
            	
            // this setup will be verified when we verify the factory
            bar.Setup(b => b.Redo()).Verifiable();

            factory.Verify();
            // At this point verifiable setups are already checked

Perform an expectation in the trace.

Marks a method as a matcher, which allows complete replacement of the built-in class with your own argument matching rules.

This feature has been deprecated in favor of the new and simpler . The argument matching is used to determine whether a concrete invocation in the mock matches a given setup. This matching mechanism is fully extensible. There are two parts of a matcher: the compiler matcher and the runtime matcher. Compiler matcher Used to satisfy the compiler requirements for the argument. Needs to be a method optionally receiving any arguments you might need for the matching, but with a return type that matches that of the argument. Let's say I want to match a lists of orders that contains a particular one. I might create a compiler matcher like the following:


            public static class Orders
            {
              [Matcher]
              public static IEnumerable<Order> Contains(Order order)
              {
                return null;
              }
            }

Now we can invoke this static method instead of an argument in an invocation:


            var order = new Order { ... };
            var mock = new Mock<IRepository<Order>>();
            
            mock.Setup(x => x.Save(Orders.Contains(order)))
                .Throws<ArgumentException>();

Note that the return value from the compiler matcher is irrelevant. This method will never be called, and is just used to satisfy the compiler and to signal Moq that this is not a method that we want to be invoked at runtime. Runtime matcher The runtime matcher is the one that will actually perform evaluation when the test is run, and is defined by convention to have the same signature as the compiler matcher, but where the return value is the first argument to the call, which contains the object received by the actual invocation at runtime:


              public static bool Contains(IEnumerable<Order> orders, Order order)
              {
                return orders.Contains(order);
              }

At runtime, the mocked method will be invoked with a specific list of orders. This value will be passed to this runtime matcher as the first argument, while the second argument is the one specified in the setup (x.Save(Orders.Contains(order))). The boolean returned determines whether the given argument has been matched. If all arguments to the expected method are matched, then the setup matches and is evaluated. Using this extensible infrastructure, you can easily replace the entire set of matchers with your own. You can also avoid the typical (and annoying) lengthy expressions that result when you have multiple arguments that use generics. The following is the complete example explained above:


            public static class Orders
            {
              [Matcher]
              public static IEnumerable<Order> Contains(Order order)
              {
                return null;
              }
              
              public static bool Contains(IEnumerable<Order> orders, Order order)
              {
                return orders.Contains(order);
              }
            }

And the concrete test using this matcher:


            var order = new Order { ... };
            var mock = new Mock<IRepository<Order>>();
            
            mock.Setup(x => x.Save(Orders.Contains(order)))
                .Throws<ArgumentException>();
                
            // use mock, invoke Save, and have the matcher filter.

Provides a mock implementation of .

Any interface type can be used for mocking, but for classes, only abstract and virtual members can be mocked. The behavior of the mock with regards to the setups and the actual calls is determined by the optional that can be passed to the constructor. Type to mock, which can be an interface or a class. The following example shows establishing setups with specific values for method invocations:


				// Arrange
				var order = new Order(TALISKER, 50);
				var mock = new Mock<IWarehouse>();

				mock.Setup(x => x.HasInventory(TALISKER, 50)).Returns(true);

				// Act
				order.Fill(mock.Object);

				// Assert
				Assert.True(order.IsFilled);

The following example shows how to use the class to specify conditions for arguments instead of specific values:


				// Arrange
				var order = new Order(TALISKER, 50);
				var mock = new Mock<IWarehouse>();

				// shows how to expect a value within a range
				mock.Setup(x => x.HasInventory(
							It.IsAny<string>(),
							It.IsInRange(0, 100, Range.Inclusive)))
					 .Returns(false);

				// shows how to throw for unexpected calls.
				mock.Setup(x => x.Remove(
							It.IsAny<string>(),
							It.IsAny<int>()))
					 .Throws(new InvalidOperationException());

				// Act
				order.Fill(mock.Object);

				// Assert
				Assert.False(order.IsFilled);

This applies only to classes, not interfaces. var mock = new Mock<MyProvider>(someArgument, 25); Behavior of the mock.Optional constructor arguments if the mocked type is a class.

Returns the mocked object value.

Specifies a setup on the mocked type for a call to to a void method.

If more than one setup is specified for the same method or property, the latest one wins and is the one that will be executed. Lambda expression that specifies the expected method invocation.


				var mock = new Mock<IProcessor>();
				mock.Setup(x => x.Execute("ping"));

Specifies a setup on the mocked type for a call to to a value returning method.

Type of the return value. Typically omitted as it can be inferred from the expression. If more than one setup is specified for the same method or property, the latest one wins and is the one that will be executed. Lambda expression that specifies the method invocation.


				mock.Setup(x => x.HasInventory("Talisker", 50)).Returns(true);

Specifies a setup on the mocked type for a call to to a property getter.

If more than one setup is set for the same property getter, the latest one wins and is the one that will be executed. Type of the property. Typically omitted as it can be inferred from the expression.Lambda expression that specifies the property getter.


				mock.SetupGet(x => x.Suspended)
					 .Returns(true);

Specifies a setup on the mocked type for a call to to a property setter.

If more than one setup is set for the same property setter, the latest one wins and is the one that will be executed. This overloads allows the use of a callback already typed for the property type. Type of the property. Typically omitted as it can be inferred from the expression.The Lambda expression that sets a property to a value.


				mock.SetupSet(x => x.Suspended = true);

Specifies a setup on the mocked type for a call to to a property setter.

If more than one setup is set for the same property setter, the latest one wins and is the one that will be executed. Lambda expression that sets a property to a value.


				mock.SetupSet(x => x.Suspended = true);

Specifies that the given property should have "property behavior", meaning that setting its value will cause it to be saved and later returned when the property is requested. (this is also known as "stubbing").

Type of the property, inferred from the property expression (does not need to be specified). Property expression to stub. If you have an interface with an int property Value, you might stub it using the following straightforward call:


				var mock = new Mock<IHaveValue>();
				mock.Stub(v => v.Value);

After the Stub call has been issued, setting and retrieving the object value will behave as expected:


				IHaveValue v = mock.Object;

				v.Value = 5;
				Assert.Equal(5, v.Value);

Specifies that the given property should have "property behavior", meaning that setting its value will cause it to be saved and later returned when the property is requested. This overload allows setting the initial value for the property. (this is also known as "stubbing").

Type of the property, inferred from the property expression (does not need to be specified). Property expression to stub.Initial value for the property. If you have an interface with an int property Value, you might stub it using the following straightforward call:


				var mock = new Mock<IHaveValue>();
				mock.SetupProperty(v => v.Value, 5);

After the SetupProperty call has been issued, setting and retrieving the object value will behave as expected:


				IHaveValue v = mock.Object;
				// Initial value was stored
				Assert.Equal(5, v.Value);

				// New value set which changes the initial value
				v.Value = 6;
				Assert.Equal(6, v.Value);

Specifies that the all properties on the mock should have "property behavior", meaning that setting its value will cause it to be saved and later returned when the property is requested. (this is also known as "stubbing"). The default value for each property will be the one generated as specified by the property for the mock.

If the mock is set to , the mocked default values will also get all properties setup recursively.

Allows the specification of a matching condition for an argument in a method invocation, rather than a specific argument value. "It" refers to the argument being matched.

This class allows the setup to match a method invocation with an arbitrary value, with a value in a specified range, or even one that matches a given predicate.

Matches any value of the given type.

Typically used when the actual argument value for a method call is not relevant.


				// Throws an exception for a call to Remove with any string value.
				mock.Setup(x => x.Remove(It.IsAny<string>())).Throws(new InvalidOperationException());

Type of the value.

Matches any value that satisfies the given predicate.

Type of the argument to check.The predicate used to match the method argument. Allows the specification of a predicate to perform matching of method call arguments. This example shows how to return the value 1 whenever the argument to the Do method is an even number.


				mock.Setup(x => x.Do(It.Is<int>(i => i % 2 == 0)))
				.Returns(1);

This example shows how to throw an exception if the argument to the method is a negative number:


				mock.Setup(x => x.GetUser(It.Is<int>(i => i < 0)))
				.Throws(new ArgumentException());

Matches any value that is in the range specified.

Type of the argument to check.The lower bound of the range.The upper bound of the range. The kind of range. See . The following example shows how to expect a method call with an integer argument within the 0..100 range.

Matcher to treat static functions as matchers. mock.Setup(x => x.StringMethod(A.MagicString())); public static class A { [Matcher] public static string MagicString() { return null; } public static bool MagicString(string arg) { return arg == "magic"; } } Will succeed if: mock.Object.StringMethod("magic"); and fail with any other call.

Options to customize the behavior of the mock.

Causes the mock to always throw an exception for invocations that don't have a corresponding setup.

Will never throw exceptions, returning default values when necessary (null for reference types, zero for value types or empty enumerables and arrays).

Default mock behavior, which equals .

Exception thrown by mocks when setups are not matched, the mock is not properly setup, etc.

A distinct exception type is provided so that exceptions thrown by the mock can be differentiated in tests that expect other exceptions to be thrown (i.e. ArgumentException). Richer exception hierarchy/types are not provided as tests typically should not catch or expect exceptions from the mocks. These are typically the result of changes in the tested class or its collaborators implementation, and result in fixes in the mock setup so that they dissapear and allow the test to pass.

Type of the value.

Matches any value that satisfies the given predicate.

Type of the argument to check. The predicate used to match the method argument. Allows the specification of a predicate to perform matching of method call arguments. This example shows how to return the value 1 whenever the argument to the Do method is an even number.


            mock.Protected()
                .Setup("Do", ItExpr.Is<int>(i => i % 2 == 0))
                .Returns(1);

This example shows how to throw an exception if the argument to the method is a negative number:


            mock.Protected()
                .Setup("GetUser", ItExpr.Is<int>(i => i < 0))
                .Throws(new ArgumentException());

Matches any value that is in the range specified.

Type of the argument to check. The lower bound of the range. The upper bound of the range. The kind of range. See . The following example shows how to expect a method call with an integer argument within the 0..100 range.


            mock.Protected()
                .Setup("HasInventory",
                        ItExpr.IsAny<string>(),
                        ItExpr.IsInRange(0, 100, Range.Inclusive))
                .Returns(false);

Matches a string argument if it matches the given regular expression pattern.

The pattern to use to match the string argument value. The following example shows how to expect a call to a method where the string argument matches the given regular expression:


            mock.Protected()
                .Setup("Check", ItExpr.IsRegex("[a-z]+"))
                .Returns(1);

Matches a string argument if it matches the given regular expression pattern.

The pattern to use to match the string argument value. The options used to interpret the pattern. The following example shows how to expect a call to a method where the string argument matches the given regular expression, in a case insensitive way:


            mock.Protected()
                .Setup("Check", ItExpr.IsRegex("[a-z]+", RegexOptions.IgnoreCase))
                .Returns(1);

Enables the Protected() method on , allowing setups to be set for protected members by using their name as a string, rather than strong-typing them which is not possible due to their visibility.

Enable protected setups for the mock.

Mocked object type. Typically omitted as it can be inferred from the mock instance. The mock to set the protected setups on.

Kind of range to use in a filter specified through .

The range includes the to and from values.

The range does not include the to and from values.

Determines the way default values are generated calculated for loose mocks.

Default behavior, which generates empty values for value types (i.e. default(int)), empty array and enumerables, and nulls for all other reference types.

Whenever the default value generated by is null, replaces this value with a mock (if the type can be mocked).

For sealed classes, a null value will be generated.

A default implementation of IQueryable for use with QueryProvider

The is a static method that returns an IQueryable of Mocks of T which is used to apply the linq specification to.

Allows creation custom value matchers that can be used on setups and verification, completely replacing the built-in class with your own argument matching rules.

See also . Provided for the sole purpose of rendering the delegate passed to the matcher constructor if no friendly render lambda is provided.

Initializes the match with the condition that will be checked in order to match invocation values.

The condition to match against actual values. This method is used to set an expression as the last matcher invoked, which is used in the SetupSet to allow matchers in the prop = value delegate expression. This delegate is executed in "fluent" mode in order to capture the value being set, and construct the corresponding methodcall. This is also used in the MatcherFactory for each argument expression. This method ensures that when we execute the delegate, we also track the matcher that was invoked, so that when we create the methodcall we build the expression using it, rather than the null/default value returned from the actual invocation.

Allows creation custom value matchers that can be used on setups and verification, completely replacing the built-in class with your own argument matching rules.

Type of the value to match. The argument matching is used to determine whether a concrete invocation in the mock matches a given setup. This matching mechanism is fully extensible. Creating a custom matcher is straightforward. You just need to create a method that returns a value from a call to with your matching condition and optional friendly render expression:


				[Matcher]
				public Order IsBigOrder()
				{
					return Match<Order>.Create(
						o => o.GrandTotal >= 5000, 
						/* a friendly expression to render on failures */
						() => IsBigOrder());
				}

This method can be used in any mock setup invocation:


				mock.Setup(m => m.Submit(IsBigOrder()).Throws<UnauthorizedAccessException>();

At runtime, Moq knows that the return value was a matcher (note that the method MUST be annotated with the [Matcher] attribute in order to determine this) and evaluates your predicate with the actual value passed into your predicate. Another example might be a case where you want to match a lists of orders that contains a particular one. You might create matcher like the following:


				public static class Orders
				{
					[Matcher]
					public static IEnumerable<Order> Contains(Order order)
					{
						return Match<IEnumerable<Order>>.Create(orders => orders.Contains(order));
					}
				}

Now we can invoke this static method instead of an argument in an invocation:


				var order = new Order { ... };
				var mock = new Mock<IRepository<Order>>();

				mock.Setup(x => x.Save(Orders.Contains(order)))
					 .Throws<ArgumentException>();

Tracks the current mock and interception context.

Having an active fluent mock context means that the invocation is being performed in "trial" mode, just to gather the target method and arguments that need to be matched later when the actual invocation is made.

A that returns an empty default value for non-mockeable types, and mocks for all other types (interfaces and non-sealed classes) that can be mocked.

Allows querying the universe of mocks for those that behave according to the LINQ query specification.

This entry-point into Linq to Mocks is the only one in the root Moq namespace to ease discovery. But to get all the mocking extension methods on Object, a using of Moq.Linq must be done, so that the polluting of the intellisense for all objects is an explicit opt-in.

Method that is turned into the actual call from .Query{T}, to transform the queryable query into a normal enumerable query. This method is never used directly by consumers.

Extension method used to support Linq-like setup properties that are not virtual but do have a getter and a setter, thereby allowing the use of Linq to Mocks to quickly initialize Dtos too :)
