Throws Null exception when I try to use DataManager

description

I want to utilize DataManager functionality provided by CUITE but it throws Null exception at

Hashtable htdata = CUITe_DataManager.GetDataRow(Type.GetType("SampleTestProject.UnitTest1",true,true), "XMLFile1", "tc2");

Am I doing anything wrong?

I have added XMLFile in project but still the same issue. Help needed

Hi.

Is the xml file marked as an "Embedded Resource"?

Can you paste the complete stack trace and point out the line number in your code please?

Thank you.

Yeah I have XML as embeded resource in properties Window.

Error is thrown at
Hashtable htdata = CUITe_DataManager.GetDataRow(Type.GetType("SampleTestProject.UnitTest1",true,true), "XMLFile1", "tc2");

Please make sure you use the complete file name with the file extension.
Hashtable htdata = CUITe_DataManager.GetDataRow(Type.GetType("SampleTestProject.UnitTest1",true,true), "XMLFile1.xml", "tc2");
Otherwise you will get a NullReferenceException as you experienced.

E:\ indicates the file path the CUITe source code at the time it was compiled of the version you are using.

Thank you.

With changeset 24881, CUITe uses a new ResourceNotFoundException in this case.
