Specflow Tests mit Nunit 3 Console Runner

Question

Ich habe kürzlich ein neues Projekt gestartet und mich für Specflow 2.1 entschieden. Es wird mit NUnit3 ausgeliefert.

Derzeit ist das Projekt eingerichtet und der Test Runner in Visual Studio wird korrekt ausgeführt, aber wenn ich versuche, die gleichen Tests vom Nunit 3 Console Runner auszuführen, erhalte ich einen Fehler.

Der Befehl ich verwende, ist nunit3-console.exe --labels=All --framework=net-4.5 Blah.Testing.Specflow.dll

I hinzugefügt zwei nativer Nunit Tests mit der gleichen Anordnung und diejenigen ausführen feinen, sein die eine specflow Test, der

habe ich versucht, versagt reflektierende Die TechTalk.Specflow-Assembly, um die CreateTestRunnerInstance-Methode zu betrachten, hat jedoch nichts Nützliches gefunden, um mich zu einer Lösung zu führen.

Answer 1

Es sieht aus wie haben Sie die SpecFlow + Runner (SpecRun) Plugin auch konfiguriert.

bei TechTalk.SpecRun.SpecFlowPlugin .Runtime.SpecRunTestRunnerManager.CreateTestRunnerInstance() in C: \ Teamcity \ BuildAgent \ work \ 245a3e4d646c0875 \ SpecFlowPlugins \ TechTalk.SpecRun.SpecFlowPlugin.2-0-0 \ Runtime \ SpecRunTestRunnerManager. cs: line 33

überprüfen Sie bitte Ihre Einstellungen plugins und unittestprovider in der app.config. Danach werden alle Feature-Code-Behind-Dateien neu generiert (einfach die Feature-Dateien speichern).
