Die obige Fehlermeldung erfolgt, wenn ich versuche, einen Testkontainer in meinem Automatisierungstestskript für das Ausführen eines MailDEV -Servers einrichten zu können, um E -Mails für einen Mail -Absender für Benutzer anzumelden,/Passwort für mein Unternehmen.

Code: Select all

[BeforeFeature(Order = TestRunSequence.RegisterObjectContainer)]
public static async Task SetConfiguration(IObjectContainer objectContainer)
{
var configuration = new ConfigurationBuilder()
.SetBasePath(AppDomain.CurrentDomain.BaseDirectory)
.AddJsonFile("appsettings.json", optional: false, reloadOnChange:  true)
.AddEnvironmentVariables() // Load [url=viewtopic.php?t=25360]environment[/url] variables
.AddUserSecrets()
.Build();
objectContainer?.RegisterInstanceAs(configuration);

var mailDevContainer= new ContainerBuilder()
.WithImage("maildev/maildev:latest")
.WithPortBinding(1080, true)
.WithPortBinding(1025, true)
.WithWaitStrategy(Wait.ForUnixContainer().UntilPortIsAvailable(1080))
.WithReuse(true)
.WithLabel("maildev-container", "MailDev")
.WithPortBinding(1080, 1080)
.WithPortBinding(1025, 1025)
.Build();

if (!isStarted)
{
await mailDevContainer.StartAsync();
isStarted = true;
}

objectContainer?.RegisterInstanceAs(mailDevContainer);

***(More code irrelevant to this issue is here)***
}

Es scheint, als würde es sich über Zeile 48 beschweren (Tests/[MYCOMPANY].[MYAPP].UI.Tests/Hooks/ConfigurationHooks.cs:line 48

); Was die Zeile widerspiegelt, wartet maildevContainer.startasync ();
Ich weiß nicht, warum dies auftritt, aber ich sehe auch einen Fehler vor dieser erwähnten Fehlermeldung: docer. Programmierung externer Konnektivität auf Endpoint Adoring_Hopper (397aEAF67AF9014DC4341DFEDC0494E52219CEB718D00FCE6160BD81E8C69A74): BINDE FÜR 0.0.0.0:1025 FAILIENT: PORT: Port ist bereits zugeteilt. Könnt ihr helfen, dies zu identifizieren?
