Skip a specific test file on travis in R

Question

My testing suite is made of multiple files. I would like to skip one of them on travis (the one related to fitting Bayesian models) because it takes to much time and fails.

I know that I can skip specific tests with testthat::skip_on_travis(). However, these work in a test_that block. Unfortunately, the part I wish to skip (from here to here) is mainly outside the test_that block (and is the model fitting occurring before testing).

I tried putting the model fitting inside a test_that block, but then the other blocks do not find the models. I also tried nested test_that block, but that seems not to work... any ideas?

Answer 1

Another option that seems to work is to check the environment variables:

if (Sys.getenv("USER") != "travis") {
  # tests to be executed...
}

Answer 2

In your testthat.R file, you can use the filter argument to test_check in order to skip entire files conditionally. This mechanism can be used to skip collections of long tests on CRAN or Travis.
