selectInput test doesn't work for me

[kismsu]

Hi, I'm trying to set up tests for my Shiny app with your package, but not all examples work for me. For instance now I can't use selectInput text. Even example you have doesn't work.

test_dir(paste0(find.package("RSelenium"), "/apps/shinytestapp/tests/"), reporter = "Tap", filter = "selectinput")
1..3
# Context controls 
not ok 1 selectInput dataSet correct

  5: queryRD(paste0(serverURL, "/session/", sessionInfo$id, "/element"), "POST", qdata = toJSON(list(using = using, value = value)), json = TRUE)

Is there any obvious reason for this?
