 =============
 
 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
-smoke tests.
+layers:
+
+1. **Core tests**: abstract domain logic unit tests agnostic of Blender
+2. **Tool tests**: low-level concrete unit tests dependant on Blender
+3. **BIM tests**: high-level integration UI and smoke tests dependant on Blender
 
 These tests use ``pytest`` as the test framework and runner, so install it:

 The BIM layer acts as a full integration test. It is not possible to fully test
 the UI, as we cannot reliably emit interface signals, nor read the interface as
