Whether experienced or novice, most SharePoint development teams can improve their processes with the help of Team Foundation Server and Visual Studio  – specifically with automated WSP builds and VS2010 Coded UI testing (which can have a much lower barrier to entry than unit testing). When a few of these capabilities are strung together, the results are incredible for dev teams. In TechEd 2012, Jay Schmelzer delivered a very good session covering the following:

• Automating the build,
• deploying the resulting WSPs to a remote SharePoint environment
• automatically running UI tests against the site.
