+##Unit Testing
+
+####Prerequisites
+
+Before running the tests in Visual Studio, or by Command line, first we need to download the required test files.
+
+To do so, we just need to run "1_DownloadTestFiles.cmd" once.  If we need to update the test files we can run it again.
+
+After the test files have been successfully downloaded, we can either run the tests in Visual Studio, or run "2_RunCoreTests.cmd" and "3_RunToolkitTests.cmd"
+
+####Overview
+
+Tests are performed against Net471, NetCore3.1 and Net5.
+
+The reason to test against the three frameworks is because there's slight differences between the platforms that makes some test to pass in one framework, and fail in the other.
+
+Most notably, the differences found are:
+
+- System.Text.Json
+  - Dependency issues: NetCore3.1 and Net5 use different depedencies by default
+  - Net471 implementation is not able to do floating point roundtrips.
+- System.Numerics.Vectors Matrix4x4.CreatePerspective  fail in Net471 when trying to use infinite far planes.
