Tests the constructor parameters.

Namespace: FastMoq
Assembly: FastMoq.Core (in FastMoq.Core.dll)

Syntax

protected void TestConstructorParameters(
	Action<Action, string, string> createAction,
	Nullable<Func<ParameterInfo, Nullable<Object>>> defaultValue,
	Nullable<Func<ParameterInfo, Nullable<Object>>> validValue
)

Protected Sub TestConstructorParameters ( _
	createAction As Action(Of Action, String, String), _
	defaultValue As Nullable(Of Func(Of ParameterInfo, Nullable(Of Object))), _
	validValue As Nullable(Of Func(Of ParameterInfo, Nullable(Of Object))) _
)

protected:
void TestConstructorParameters(
	Action<Action^, String^, String^>^ createAction, 
	Nullable<Func<ParameterInfo^, Nullable<Object^>>^> defaultValue, 
	Nullable<Func<ParameterInfo^, Nullable<Object^>>^> validValue
)

Parameters

createAction: Type: Action<(Of <(<'Action, String, String>)>)>
The create action.

defaultValue: Type: Nullable<(Of <(<'Func<(Of <(<'ParameterInfo, Nullable<(Of <(<'Object>)>)>>)>)>>)>)>
The default value.

validValue: Type: Nullable<(Of <(<'Func<(Of <(<'ParameterInfo, Nullable<(Of <(<'Object>)>)>>)>)>>)>)>
The valid value.

Examples

CreateComponent allows creating the component when desired, instead of in the base class constructor.
