CleanArchitecture Template Tests

1. Create new project from the CleanArchitecture template:

   dotnet new ssw-ca -o CleanTesting
   cd CleanTesting

2. Open in an IDE and explore the test

3. Check out the use of TestContainers - its better to use a container over an in-memory database for testing as it more closely resembles production. /WebApi.IntegrationTests/Common/TestingDatabaseFixture.cs
