Did you know there are two ways to Deploy files to be used when executing unit tests in VSTS.
You can added them to the .Testrunconfig:
Or using the DeploymentItem attribute on the TestMethod:
[TestMethod,DeploymentItem(@"Bin\fr-CA\Thermo.Automation.Foundation.Tests.resources.dll","fr-CA")]
public void Multilanguage()
{
Message msg = Message.Retrieve(Messages.Multilanguage);
msgServ.Post(msg);
Assert.IsTrue(msgServ.ValidateMessageReceived("English message"));
Thread.CurrentThread.CurrentUICulture = new CultureInfo("fr-CA");
Message msgFr = Message.Retrieve(Messages.Multilanguage);
msgServ.Post(msgFr);
Assert.IsTrue(msgServ.ValidateMessageReceived("French message"));
}
