Automated Testing OpenXML SDK

Hi, I'm implementing ms word document generation using content controls and OpenXML SDK. I'd like to have some automated testing for that code (unit tests or some easy UI automation tests).

Does anyone has expericnce with testing MS Word document generation? What are the possible options?

Thanks in advance!

+2 A:

No, I haven't done unit testing of MS Word Document generation, but as Ingó Vals says, it shouldn't be any different from any other form of unit testing.

1) [Optional - to ensure that you understand correct usage of the SDK for your needs]. Work out how your app should drive the SDK. Write some test scripts that mimic intended functionality and ensure that the Word documents they generate meet your expectations.

2) Create an interface (or interfaces) that contain methods that correspond to the functionality that you need for your documentation generation. Note: the interface does not need to offer the full functionality of the OpenXML SDK - only the functionality that you need for your application.

3) Create a concrete implementation of your interface, which forwards calls to the OpenXML SDK

4) Utilise the interface you created in your application to perform document generation.

5) Use NUnit and NMock (or similar) to write unit tests that drive the generation layer of your application. These tests should use a mocked interface, rather than an instance of the concrete implementation. You can now assert in your tests that your generation layer behaves as you expect.

Thanks for the answer, but the thing is that I'm intrested in testing code that directly manipulates Open XML SDK. All the rest I can separate or mock, that's clear. Using mocks insdead of actually calling Open XML SDK is not to my liking, as what I want to test is that my code works fine with SDK. Someone may argue that it's not a pure unit test, but that what is realy missing in my current test.

What I described is unit testing your code. I would call what you want an integration test. In which case I guess you could get the SDK to output Word XML and write a method that compares the resulting DOM with the DOM you expect.

Yep, unit or integration or UI automation or what will work. To sumarrize any type of automated testing that will allow to do verification (Assert part of the test). Will check DOM comparison. Thanks a lot!

I aggree with Seb Rose here. Create the document or document part you expect to come out ( with all the bells and wistles to ensure you test everything ) and compare it to what you create in the test.

I have generated OpenXml Powerpoints documents that validates using XML SDK 2.0 tools and works in Office 2007 on my PC but when opening the document on another machine using Office Powerpoint 2007 it complains and says the format is not valid
