[英]Unknown command: --environment=Development during testing
我創建了一個 ASP.NET 項目並為它編寫了一些集成測試。 但是當我嘗試運行dotnet test
時,會出現:
Starting test execution, please wait...
A total of 1 test files matched the specified pattern.
The active test run was aborted. Reason: Test host process crashed : Unknown command: --environment=Development
Test Run Aborted with error System.Exception: One or more errors occurred.
---> System.Exception: Unable to read beyond the end of the stream.

at Microsoft.VisualStudio.TestPlatform.CommunicationUtilities.TcpClientExtensions.MessageLoopAsync(TcpClient client, ICommunicationChannel channel, Action`1 errorHandler, CancellationToken cancellationToken)
--- End of inner exception stack trace ---.
據我了解,有些東西試圖用--environment=Development
運行 dotnet 可執行文件,但即使在Microsoft docs中使用了這個參數,它也是無效的。
我嘗試創建新的 ASP.NET 項目(沒有控制器、服務、數據庫等。只是 API 什么都不做,並且測試為空),但我無法再次重現該錯誤。
最初我偶然在同一個文件夾中創建了我的項目和解決方案,並且不得不手動將項目移動到子文件夾。 在我這樣做之后一切都很好,所以我認為它很好。 也許這就是原因。
以下是我在測試期間訪問應用程序的方式:
// TestingApplication.cs
public class TestingApplication : WebApplicationFactory<Program>
{
private readonly Guid _appId = Guid.NewGuid();
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
// Add mock/test services to the builder here
builder.ConfigureServices(services =>
{
services.AddMvcCore().AddApplicationPart(typeof(Program).Assembly);
services.AddScoped(sp => new DbContextOptionsBuilder<EfDbContext>()
.UseSqlServer(
$"DATABASE CONNECTION STRING")
.UseApplicationServiceProvider(sp)
.Options);
});
}
protected override IHost CreateHost(IHostBuilder builder)
{
var host = base.CreateHost(builder);
using (var serviceScope = host.Services.GetRequiredService<IServiceScopeFactory>().CreateScope())
{
var context = serviceScope.ServiceProvider.GetRequiredService<EfDbContext>();
context.Database.EnsureCreated();
}
return host;
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
using (var serviceScope = Server.Services.GetRequiredService<IServiceScopeFactory>().CreateScope())
{
var context = serviceScope.ServiceProvider.GetRequiredService<EfDbContext>();
context.Database.EnsureDeleted();
}
}
}
// BaseTest.cs
public class BaseTest : IDisposable, IClassFixture<TestingApplication>
{
protected readonly TestingApplication Application;
private HttpClient? _client;
protected HttpClient Client => _client ??= Application.CreateClient();
public BaseTest(TestingApplication testingApplication)
{
Application = testingApplication;
}
public void Dispose()
{
Application.Dispose();
}
}
更多信息:
<InternalsVisibleTo Include="NameOfTestsProject" />
添加到主項目文件中,但無論如何它都不起作用。有誰知道問題是什么?
UPD我想通了
好的,所以這只是復制粘貼別人的代碼而不檢查的另一個例子。 我復制了以下內容:
if (args[0] == "something") {
...
} else if (args[0] == "something else") {
...
} else {
// exit with code 1 here and print error
}
在我的 Program.cs 中。 它本身運行良好,但在測試時導致了這個問題。
