Usability testing is an important piece of good user centered design. I have worked with usability experts who have tested my designs, as well as conducted some testing myself, both formally and informally with real users. The first example comes from an internal analytics team that looked at two versions of a page (A/B split test) to determine which was more effective. The UX team had access to this information and could make informed decisions based on the resulting data.
Secondly is an example of a more formal test I designed, conducted and documented, focusing on the navigation and provider search engine of a healthcare website.
