Aspnetcore: dotnet-watch no projeto não detecta novos arquivos

Descreva o bug

dotnet-watch em um projeto conforme descrito “Desenvolva aplicativos ASP.NET Core usando um inspetor de arquivos” e, especificamente, a seção Executar testes usando dotnet watch , não detecta adições de novos arquivos.

Reproduzir

Crie um diretório para o projeto:

mkdir DotNetWatcherIssueDemo

Mude para o diretório do projeto:

cd DotNetWatcherIssueDemo

Inicialize-o com um novo projeto de teste:

dotnet new nunit

Inicie o VS Code no diretório que contém o projeto de teste:

code .

Peça para assistir o projeto e executar testes nas mudanças:

dotnet watch test

Nesse estágio, você deve ver o resultado:

watch : Started
Build started, please wait...
Build completed.

Test run for A:\temp\DotNetWatchIssueDemo\bin\Debug\netcoreapp2.2\DotNetWatchIssueDemo.dll(.NETCoreApp,Version=v2.2)

Total tests: 1. Passed: 1. Failed: 0. Skipped: 0.
Test Run Successful.
Test execution time: 0.9364 Seconds
watch : Exited
watch : Waiting for a file to change before restarting dotnet...

Agora adicione um novo teste a UnitTest1.cs :

diff --git a/UnitTest1.cs b/UnitTest1.cs
index 66ec70e..f6406e7 100644
--- a/UnitTest1.cs
+++ b/UnitTest1.cs
@@ -14,5 +14,11 @@ namespace Tests

         }

+        public void Test2()
+        {
+            Assert.Pass();
+        }
     }
 }
\ No newline at end of file

dotnet watch pegará a mudança, executará _dois_ testes com sucesso e continuará a observar novas mudanças no arquivo:

watch : Started
Build started, please wait...
Build completed.

Test run for A:\temp\DotNetWatchIssueDemo\bin\Debug\netcoreapp2.2\DotNetWatchIssueDemo.dll(.NETCoreApp,Version=v2.2)

Starting test execution, please wait...

Total tests: 2. Passed: 2. Failed: 0. Skipped: 0.
Test Run Successful.
Test execution time: 0.9698 Seconds

watch : Waiting for a file to change before restarting dotnet...

Em um shell separado, cd no diretório do projeto e adicione um novo arquivo de teste:

dotnet new nunit-test -n UnitTest2 -o .

Comportamento esperado

Na última etapa, eu esperava que dotnet watch pegasse a nova alteração do arquivo, construísse e executasse novamente todos os testes, mas isso não fez nada.

Parece que ele constrói uma lista estática de arquivos e só observa as alterações. Se eu tocar / forçar o salvamento do arquivo de projeto ( DotNetWatcherIssueDemo.csproj ) então dotnet watch detecta a mudança, reconstrói a lista de observação e detecta mudanças no arquivo adicionado, mas novamente, não para qualquer novo arquivo adicionado posteriormente.
