new RequestContext() throws exception

[JeffGilbert]

Hi,
I'm trying to create some unit tests that involve the RequestContext, but I get an exception when I try to construct it. Is it possible/practical for me to create a new RequestContext() like this?

Code: Select all

    [Fact()]
    public void HasAccessTest()
    {
        var serverManager = new ServerManager();
        var requestHeader = new RequestHeader();
        var requestContext = new RequestContext(serverManager, requestHeader, ServiceType.ActivateSession);  //throws exception
        var accessControlManager = container.Resolve<AccessControlManager>();
        Assert.True(accessControlManager.HasAccess(requestContext));
    }

Exception:

Code: Select all

Object reference not set to an instance of an object.
   at UnifiedAutomation.UaServer.ServerContext..ctor(ServerManager server)
   at UnifiedAutomation.UaServer.RequestContext..ctor(ServerManager server, RequestHeader requestHeader, ServiceType requestType)
   at McOpcUaServerTests.OPC.AccessControlManagerTests.HasAccessTest() in C:\Repo\OPC UA\McOpcUaServerTests\OPC\AccessControlManagerTests.cs:line 29

Thanks,
Jeff

Hello,

You cannot create a RequestContext using a ServerManager that has not been passed as argument in the method ApplicaionInstance.Start. The class RequestContext shall not be used in this way.

Your code could look like this:

Code: Select all

ApplicationInstance app = new ApplicationInstance();
var serverManager = new ServerManager();
var requestHeader = new RequestHeader();
app.Start(serverManager, null, null);
var requestContext = new RequestContext(serverManager, requestHeader, ServiceType.ActivateSession);  //does NOT throw exception
