We have a TRDX report with Object data source - that has Object = "XYZReport" and DataMember = "GetData()"

When the report is opened via viewer - everything runs fine.

When the report is rendered in a unit test method in a unit test project, it does not invoke GetData() method at all and renders empty report. The XYZReport class is in a separate Project/Classlibrary and Unit Test project references it. 

Any clue what could be happening and how we can resolve this?

Hello Piyush Bhatt,

Perhaps the report viewer project references the correct assemblies which allow the report to retrieve its data. The unit test project, on the other hand, might not reference the required assemblies and the data cannot be retrieved there.

Since you do not need to create any unit tests for Telerik Reporting modules, you can only retrieve the data and check that it is correct in your unit test project i.e., test only the GetData() method. Testing that Telerik Reporting produces correct report output based on given input data is done on our end.
