 The BlenderBIM Add-on has three layers of tests for each of its three technology
 layers. These roughly form a test pyramid, moving from many abstract domain
 logic tests, to low-level concrete unit tests, to a minimal number of UI and

 All development is expected to use test driven development, and so we expect
 test coverage to be 100% where it is technically possible to test.

 Because the BlenderBIM Add-on depends on IfcOpenShell, it is advised to also run
 tests for IfcOpenShell and its Python bindings, which is not covered in this
