Chapter 7. Testing a WebDAV Server

WHAT'S IN THIS CHAPTER?

• Introduction to the WebDAV component

• Development of the WebDAV component

• Integrating different test methods into an existing unit testing setup

Besides the violation of standards that almost every client performs, we had to deal with code that was very hard to test with the default way of unit testing. Integration and acceptance testing are two techniques discussed in this chapter.
