Getting Started

Open the GingerbreadAI.NeuralNetwork.Test solution file.

Prerequisites

Visual Studio 2019 (with dotnet core 3.1).

Unit tests

All unit tests should be runnable from the GingerbreadAI solution.

Long running tests

Longer running tests that produce a report need to be run in debug mode, and can be found in the GinbergreadAI.NeuralNetwork.Test project (in the GingerbreadAI solution).
