And I forgot to show that in .travis.yml we do of course set this, and also
request a Redis server:


env:
  global:
    - _R_CHECK_FORCE_SUGGESTS_=FALSE
    - RunRcppRedisTests=yes

services:
  - redis-server

|     ## Run tests

|     ....

| This is generic, and you can surely adapt it from testthat.

| 
| 
| ## force tests to be executed if in dev release which we define as

| if (length(strsplit(packageDescription("Rcpp")$Version, "\\.")[[1]]) > 3) {	
|     if (Sys.getenv("RunAllRcppTests") != "no") { 				
|         message("Setting \"RunAllRcppTests\"=\"yes\" for development release\n")
|         Sys.setenv("RunAllRcppTests"="yes")
|     }
| }
| 
|     
| Hope this helps,  Dirk
