How do you avoid caching during development?

Is there a simple way to prevent all caching when testing the appearance of changes to the site? I use WP Super Cache. I can delete its cache using the option provided, delete the cache for my browser, and still some changes to CSS or widgets do not refresh. I try other work-arounds like switching browsers or computers, but there must be a more stream-lined workflow where I can ensure I’m viewing the changes I made and not some cached earlier format? What’s the best solution for this?

Keeping WP database synced across multiple developers using git

I’m working on improving my git workflow as it applies to my WordPress development projects. Often, when developing a content management system, I’ll create a development server (like http://dev.finalsitename.com) containing the custom post types and taxonomies that will be used in the production version. This allows my client to begin adding their content to the site.
