T4Templates

T4 templates to use with T4Toolbox

Usage

1. Install T4Toolbox
2. Add template to a project (You can use NuGet)
3. Set "Custom Tool Template" to desired template

ImplementNotifyPropertyChanged.tt

Define properties in an interface.

public interface IClass1Properties
{
    string StringProperty { get; set; }
    int IntProperty { get; set; }
}

Define partial class with ImplementNotifyPropertyChanged attribute

[ImplementNotifyPropertyChanged(typeof(IClass1Properties))]
public partial class Class1 : IClass1Properties
{
}

Properties will be generated with NotifyPropertyChanging and NotifyPropertyChanged events.

You can define methods with names On<propName>Changing and On<propName>Changed. They will be called besides firing OnPropertyChanging and OnPropertyChanged events.

[ImplementNotifyPropertyChanged(typeof(IClass1Properties))]
public partial class Class1 : IClass1Properties
{
    protected void OnStringPropertyChanged(string oldValue, string newValue)
    {
    // do some stuff with oldValue or newValue
    }
}

ImplementPropertyChangedCaliburn.tt

Same as ImplementNotifyPropertyChanged template but uses PropertyChangedBase from Caliburn.Micro framework. PropertyChangedBase dispatches all property changed events to UI thread.

Note that INotifyPropertyChanging is not implemented in PropertyChangedBase. Everything else is the same as ImplementNotifyPropertyChanged template.

AddDataMsTests.tt

Add partial keyword to a test class

[TestClass]
public partial class UnitTest1
{

Add a method to a test class with DataTestMethod attributes

[DataTestMethod("10", 10)]
[DataTestMethod("20", 20)]
[DataTestMethod("30", 30)]
private void DataTest(string stringParam, int intParam)
{
    Assert.AreEqual(intParam, Int32.Parse(stringParam));
}

Test methods will be generated for each DataTestMethod attribute.

If you set the Result attribute property the result of a method will be asserted.

[DataTestMethod("10", Result = 10)]
[DataTestMethod("12", Result = 12)]
private int DataTestWithResult3(string stringParam)
{
    return Int32.Parse(stringParam);
}

Other properties of DataTestMethod attribute are:

• Message
• TestName
• Description
• ExpectedException
• Ignore
• Priority
• Timeout
• WorkItem

They translate to MsTest attributes. You can also use original attributes and they will be added to all generated tests. The attributes will still be overwritten with properties of DataTestMethod attribute. Description attribute will be formatted using test parameters and result.

[DataTestMethod("10", Result = 10, Priority = 3)]
[DataTestMethod("12", Result = 12)]
[Priority(10)]
[Description("Test for \"{0}\" should return {1}")]
private int DataTest(string stringParam)
{
    return Int32.Parse(stringParam);
}

Following test will be generated from this code.

[TestMethod]
[Priority(3)]
[Description("Test for \"10\" should return 10")]
public void DataTest_10_10()
{
    Assert.AreEqual(10, DataTest("10"));
}

[TestMethod]
[Description("Test for \"12\" should return 12")]
[Priority(10)]
public void DataTest_12_12()
{
    Assert.AreEqual(12, DataTest("12"));
}
