Unit Testing / Performance Testing approaches for SharePoint Projects

Question

Its sort of an open ended question but can anybody share the experiences, approaches, tools and infrastructure to implement following in their SharePoint Projects:

1. Unit Testing
2. Performance Testing
3. Load Testing
4. Integration Testing

It will be great if people can share any pitfalls they had in their past projects. How a SharePoint Project was different then a normal .NET project?

Answer 1

Unit Testing on SharePoint only really begins to work properly when you mock the SharePoint object model using one of a few methods.

Andrew Woodward over at 21apps.com has documented his findings of this, particularly with using TypeMock Isolator for SharePoint. http://www.21apps.com/category/agile/testing/

I also seen a recent presentation of his which demonstrated UI Testing Features available in Visual Studio 2010 Ultimate, which was quite interesting. (Slide Deck: http://www.21apps.com/sharepoint/slides-ui-testing-bpc10/)

For Load Testing, I have seen a good presentation from Steve Smith of Combined Knowledge about using Visual Studio for Load Testing a SharePoint farm. If you contact him through Twitter I'm sure he may be able to point you to resources regarding this: http://twitter.com/stevesmithck

You can use Pex and Moles to unit test SharePoint in isolation. There are 2 tutorials to get started, available from Microsoft at:

The tutorials are:

• Unit Testing SharePoint with Moles
• Unit Testing SharePoint with Behaviors
