Comment exécuter les tests unitaires en mode STAThread ?

Question

Je voudrais tester une application qui utilise le presse-papiers (WindowsForms) et j'ai besoin du presse-papiers dans mes Unittests également. Pour l'utiliser, il faudrait qu'elle tourne en mode STA, mais comme le Testfixture NUnit n'a pas de méthode main, je ne sais pas où/comment l'annoter...

Merci !

Answer 1

Si vous utilisez nunit 2.5+, vous pouvez utiliser le nouvel outil The RequiresSTAAttribute en classe

[TestFixture, RequiresSTA]

ou au niveau de l'assemblage.

[assembly:RequiresSTA]

Pas besoin de fichier de configuration. Vérifiez : http://www.nunit.org/index.php?p=requiresSTA&r=2.5

Answer 2

Pour NUnit 2.2, 2.4 (Voir la solution simple ci-dessous pour 2.5) :

Ajoutez un fichier app.config au projet contenant vos tests unitaires et incluez les éléments suivants :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="NUnit">
        <section name="TestRunner" type="System.Configuration.NameValueSectionHandler"/>
    </sectionGroup>
    </configSections>
    <NUnit>
        <TestRunner>
            <add key="ApartmentState" value="STA"/>
        </TestRunner>
    </NUnit>
</configuration>

Vous pouvez vérifier que le threading de l'appartement est STA avec le code C# suivant :

if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA)
{
   throw new ThreadStateException("The current threads apartment state is not STA");
}

Answer 3

Dans NUnit 2.6.1+, vous pouvez utiliser la fonction /appartement=STA en ligne de commande :
