/**
 * Helper called by test cases to generate a setUp routine.
 *
 * By default you would call this without options, but it is useful to
 * be able to plug options in during development for quick and easy
 * debugging.
 *
 * @example
 *   buster.testCase("Foobar", {
 *     setUp: testutils.build_setup({verbose: true}),
 *     // ...
 *   });
 *
 * @param opts {Object} These options allow quick-and-dirty test-specific
 *   customizations of your test environment.
 * @param opts.verbose {Bool} Enable all debug output (then cover your ears
 *   and run)
 * @param opts.verbose_ws {Bool} Enable tracing in the Remote class. Prints
 *   websocket traffic.
 * @param opts.verbose_server {Bool} Set the -v option when running rippled.
 * @param opts.no_server {Bool} Don't auto-run rippled.
 * @param host {String} Identifier for the host configuration to be used.
