1 | # RhinoCommon Unit Testing
2 |
3 | ## Intro
4 | Example of unit testing RhinoCommon from within the Visual Studio test runner on windows.
5 |
6 | ## Prerequisites
7 | Rhino 7
8 | https://www.rhino3d.com/download/Rhino/7.0
9 |
10 | Visual Studio 2019
11 | https://www.visualstudio.com/downloads/
12 |
13 | ## Test Framework
14 | This project provides examples for XUnit and MS Test,
15 | but the principles would be easily transferable to other frameworks if needs.
16 |
17 | ## How to Run
18 | - Build the solution
19 | - Test should appear in Visual Studio Test Explorer
20 | - Set test enviroment to x64
21 | `Test > Test Settings > Default Processor Architecture > x64`
22 | - Click `Run All` to run the tests
23 |
24 | ## Further Reading
25 | For more info on using Rhino in a headless environment see the Rhino Compute project:
26 | https://github.com/mcneel/compute.rhino3d
27 |
28 | ## Troubleshooting
29 | - Note that when Rhino is in headless mode there is no document defined.
30 | The static property `RhinoDoc.ActiveDoc` will thus be null which may trip up your plugin code.
31 |
32 | - If you have any problems getting this to work or you have a more complex use case,
33 | then please get in touch via the issue tracker.
