Type Parameters

Constructors

DbContextMock()

Initializes an instance of the mock with Moq.MockBehavior.Default behavior.

Declaration
public DbContextMock()
Examples
var mock = new Mock<IFormatProvider>();

DbContextMock(MockBehavior)

Initializes an instance of the mock with the specified Moq.MockBehavior behavior.

Declaration
public DbContextMock(MockBehavior behavior)
Parameters
Type Name Description
MockBehavior behavior

Behavior of the mock.
Examples
var mock = new Mock<IFormatProvider>(MockBehavior.Strict);

DbContextMock(MockBehavior, params object[])

Initializes an instance of the mock with a specific Moq.MockBehavior behavior and with the given constructor arguments for the class.

Declaration
public DbContextMock(MockBehavior behavior, params object[] args)
Parameters
Type Name Description
MockBehavior behavior

Behavior of the mock.
object[] args

Optional constructor arguments if the mocked type is a class.
Remarks

The mock will try to find the best match constructor given the constructor arguments, and invoke that to initialize the instance. This applies only to classes, not interfaces.

DbContextMock(Expression<Func<TEntity>>, MockBehavior)

Initializes an instance of the mock using the given constructor call including its argument values and with a specific Moq.MockBehavior behavior.

Declaration
public DbContextMock(Expression<Func<TEntity>> newExpression, MockBehavior behavior = MockBehavior.Default)
Parameters
Type Name Description
Expression<Func<TEntity>> newExpression

Lambda expression that creates an instance of T.
MockBehavior behavior

Behavior of the mock.
Examples
var mock = new Mock<MyProvider>(() => new MyProvider(someArgument, 25), MockBehavior.Loose);

DbContextMock(params object[])

Initializes an instance of the mock with Moq.MockBehavior.Default behavior and with the given constructor arguments for the class. (Only valid when T is a class.)

Declaration
public DbContextMock(params object[] args)
Parameters
Type Name Description
object[] args

Optional constructor arguments if the mocked type is a class.
Remarks

The mock will try to find the best match constructor given the constructor arguments, and invoke that to initialize the instance.This applies only for classes, not interfaces.

Examples
var mock = new Mock<MyProvider>(someArgument, 25);

Properties

CallBase

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

Declaration
public override bool CallBase { get; set; }
Property Value
Type Description
bool
Overrides
Moq.Mock<TEntity>.CallBase

Methods

SetupDbContextSetMethods(PropertyInfo)

Configures the Set<TEntity> style methods on the mocked DbContext for the supplied DbSet property.

Declaration
public void SetupDbContextSetMethods(PropertyInfo propertyInfo)
Parameters
Type Name Description
PropertyInfo propertyInfo

The DbSet property being mapped back to the corresponding Set<TEntity> methods.

SetupDbSetProperties(PropertyInfo, object)

Configures DbSet-related properties on the mocked DbContext.

Declaration
public virtual void SetupDbSetProperties(PropertyInfo propertyInfo, object value)
Parameters
Type Name Description
PropertyInfo propertyInfo

The DbSet property to configure.
object value

The value the property should return.

SetupDbSetPropertyGet(PropertyInfo, object)

Configures the getter for a DbSet property on the mocked DbContext.

Declaration
public void SetupDbSetPropertyGet(PropertyInfo propertyInfo, object value)
Parameters
Type Name Description
PropertyInfo propertyInfo

The DbSet property whose getter should be configured.
object value

The value the getter should return.

SetupDbSets(Mocker)

Configures all DbSet properties and related helper methods for the current DbContext mock.

Declaration
public DbContextMock<TEntity> SetupDbSets(Mocker mocks)
Parameters
Type Name Description
Mocker mocks

The owning mocker used to resolve nested set dependencies.
Returns
Type Description
DbContextMock<TEntity>

The current DbContext mock instance for fluent chaining.

SetupSetMethod(Type, Delegate, Type[]?, object?[]?)

Configures the generic Set<TEntity> method for the supplied entity type.

Declaration
public void SetupSetMethod(Type setType, Delegate propValueDelegate, Type[]? types = null, object?[]? parameters = null)
Parameters
Type Name Description
Type setType

The entity type represented by the configured DbSet.
Delegate propValueDelegate

A delegate that returns the DbSet instance for the configured entity type.
Type[] types

Optional generic type arguments to apply when building the setup expression.
object[] parameters

Optional method parameters to use while building the setup expression.
