func (a *Assertions) HTTPBodyContainsf(handler http.HandlerFunc, method string, url string, values url.Values, str interface{}) {
	HTTPBodyContainsf(a.t, handler, method, url, values, str)
}
HTTPBodyContainsf asserts that a specified handler returns a
body that contains a string.

a.HTTPBodyContainsf(myHandler, "www.google.com", nil, "I'm Feeling Lucky", "error message %s", "formatted")

Returns whether the assertion was successful (true) or not (false).
