How to Extend BaseWebAiiTest Class Functionality

A possible scenario is to use same functionality in most of the tests in the project. It is possible to implement a method which will be available in each code behind test files in the project. The approach to this problem is to extend the BaseWebAiiTest class and all test files to inherit from the new extended class.

Steps to implement such approach are as follows:

1.  Create a new project

2.  Add a stand alone class file ExtendedBaseWebAiiTest which inherits from the abstract class BaseWebAiiTest. A sample implementation of such file containing the method PrintMessage() is given below:

    using ArtOfTest.WebAii.Design;

    namespace ExtendBaseWebAiiTestProject
    {
        public class ExtendedBaseWebAiiTest : BaseWebAiiTest
        {
            // this method will be available in each test code behind file coded step
            public void PrintMessage(string message)
            {
                Log.WriteLine(message);
            }
        }
    }

    Imports ArtOfTest.WebAii.Design

    Namespace ExtendBaseWebAiiTestProject

        Public Class ExtendedBaseWebAiiTest
            Inherits BaseWebAiiTest

            Public Sub PrintMessage(ByVal message As String)
                Log.WriteLine(message)
            End Sub
        End Class
    End Namespace

3.  Close the project and edit project settings file (Settings.aiis - located in the project folder) to use ExtendedBaseWebAiiTest as a base class to each test in the project as shown on the next screen-shot:

4.  Re-open the project, add a WebTest and a coded step inside. Then in the step it will be available the PrintMessage() defined in the ExtendedBaseWebAiiTest class. Below is given a sample of the code behind file of the WebTest.

    using ArtOfTest.WebAii.Core;
    using ArtOfTest.WebAii.Design.Execution;

    namespace ExtendBaseWebAiiTestProject
    {
        public class WebTest : ExtendedBaseWebAiiTest
        {
            [CodedStep(@"Print From ExtendedBaseAiiTest Method")]
            public void PrintCodedStep()
            {
                this.PrintMessage("This is printed from extended base class method");
            }
        }
    }

    Imports ArtOfTest.WebAii.Core
    Imports ArtOfTest.WebAii.Design.Execution

    Namespace ExtendBaseWebAiiTestProject

        Public Class WebTest
            Inherits ExtendedBaseWebAiiTest

            <CodedStep("Print From ExtendedBaseAiiTest Method")>
            Public Sub PrintCodedStep()
                Me.PrintMessage("This is printed from extended base class method")
            End Sub
        End Class
    End Namespace
