Samples

The sample project contains the basic usage of the ricaun.RevitTest Framework.

• RevitTest.Samples
• RevitTest.Language

Install

To install the ricaun.RevitTest.TestAdapter, you can use the NuGet package manager.

PackageReference

The main package is ricaun.RevitTest.TestAdapter that manage the NUnit test execution of tests inside Revit.

The machine need to have the Autodesk Revit installed to work.

<PackageReference Include="NUnit" Version="3.13.3" />
<PackageReference Include="ricaun.RevitTest.TestAdapter" Version="*" />

.Net Core

If you are using .Net Core, you need to add the Microsoft.NET.Test.Sdk package to the .csproj file.

<PackageReference Include="Microsoft.NET.Test.Sdk" Version="*" Condition="!$(TargetFramework.StartsWith('net4'))" />

IsTestProject

If your are using dotnet test to execute the tests, you need to add the IsTestProject property to the .csproj file.

<IsTestProject>true</IsTestProject>

Example

The framework injects the UIApplication, UIControllerApplication, Application, and ControllerApplication Revit objects to the tests methods, use in the method with [OneTimeSetUp] or [SetUp].

using Autodesk.Revit.UI;
using NUnit.Framework;

public class RevitTest
{
    private UIApplication uiapp;
    [OneTimeSetUp]
    public void Setup(UIApplication uiapp)
    {
        this.uiapp = uiapp;
    }
    [Test]
    public void VersionName()
    {
        Assert.IsNotNull(uiapp);
        System.Console.WriteLine(uiapp.Application.VersionName);
    }
}

Loading

• TestAdapter: The NUnit TestAdapter is responsible for executing the Console and waits for the tests results.
• Console: The Console application responsible for communicating with Revit, installing the Application, and opening/closing Revit.
• Application: The Revit Plugin application is responsible for executing the tests sent by Console.

FAQ

The ricaun.RevitTest Framework is free to use ?

Yes.

What are the requirements to use ricaun.RevitTest Framework ?

It is a requirement to have Autodesk Revit installed on the machine to run the tests in the official software.

The ricaun.RevitTest Framework is open-source ?

Not available yet.

Do you need an account to use the ricaun.RevitTest Framework ?

Yes, an Autodesk account is required inside Revit.

The ricaun.RevitTest Framework collects any use data ?

No.

The ricaun.RevitTest Framework works offline ?

Yes.

The ricaun.RevitTest Framework works with Design Automation for Revit ?

Yes, is possible to switch the Console to run the tests using the Design Automation for Revit instead of the Revit for desktop. (Not available yet)

The ricaun.RevitTest Framework works in Rider ?

I tested with Rider, and works with some issues: RevitTest in Rider - 1.1.2-beta

Do you have plans to create a similar test framework for AutoCAD or Inventor ?

Could be possible, but I only use Revit so I don't have the incentive to do that.

How the ricaun.RevitTest Framework knows what Revit version to open ?

The TestAdapter checks for some RevitApi reference in the test assembly and get the version from it. If not found, the TestAdapter will use the lowest version of Revit installed in the machine.

How the force to use a specific Revit version ?

To overwrite the version selection of the TestAdapter, you can use the AssemblyMetadataAttribute property with NUnit.Version in the test project, like this:

In the .cs file:

[assembly: System.Reflection.AssemblyMetadata("NUnit.Version", "2024")]

Or in the .csproj file:

<ItemGroup>
  <AssemblyAttribute Include="System.Reflection.AssemblyMetadataAttribute">
    <_Parameter1>NUnit.Version</_Parameter1>
    <_Parameter2>2024</_Parameter2>
  </AssemblyAttribute>
</ItemGroup>

How the force to use a specific Revit language ?

To force the TestAdapter to open Revit with a specific language, you can use the AssemblyMetadataAttribute property with NUnit.Language in the test project, like this:

In the .cs file:

[assembly: System.Reflection.AssemblyMetadata("NUnit.Language", "ENU")]

Or in the .csproj file:

<ItemGroup>
  <AssemblyAttribute Include="System.Reflection.AssemblyMetadataAttribute">
    <_Parameter1>NUnit.Language</_Parameter1>
    <_Parameter2>ENU</_Parameter2>
  </AssemblyAttribute>
</ItemGroup>

How the force to open a new Revit process ?

By default TestAdapter uses the Revit process opened with the same version to run the tests. To overwrite and force to open a new process, you can use the AssemblyMetadataAttribute property with NUnit.Open in the test project, like this:

In the .cs file:

[assembly: System.Reflection.AssemblyMetadata("NUnit.Open", "true")]

Or in the .csproj file:

<ItemGroup>
  <AssemblyAttribute Include="System.Reflection.AssemblyMetadataAttribute">
    <_Parameter1>NUnit.Open</_Parameter1>
    <_Parameter2>true</_Parameter2>
  </AssemblyAttribute>
</ItemGroup>

How the force to close Revit after the test finish ?

By default TestAdapter does not closes Revit after finish a test. To overwrite and force to close Revit, you can use the AssemblyMetadataAttribute property with NUnit.Close in the test project, like this:

In the .cs file:

[assembly: System.Reflection.AssemblyMetadata("NUnit.Close", "true")]

Or in the .csproj file:

<ItemGroup>
  <AssemblyAttribute Include="System.Reflection.AssemblyMetadataAttribute">
    <_Parameter1>NUnit.Close</_Parameter1>
    <_Parameter2>true</_Parameter2>
  </AssemblyAttribute>
</ItemGroup>

How to enable log in the TestAdapter ?

The log verbosity has two levels 1(Normal) and 2(Debug), to enable you can use the AssemblyMetadataAttribute property with NUnit.Verbosity in the test project, like this:

In the .cs file:

[assembly: System.Reflection.AssemblyMetadata("NUnit.Verbosity", "1")]

Or in the .csproj file:

<ItemGroup>
  <AssemblyAttribute Include="System.Reflection.AssemblyMetadataAttribute">
    <_Parameter1>NUnit.Verbosity</_Parameter1>
    <_Parameter2>1</_Parameter2>
  </AssemblyAttribute>
</ItemGroup>
