tests regarding bad connections will fail because I haven't written a new failstate yet, eg. :

test_that("get_acoustic_deployments() returns error for incorrect connection", {
  expect_error(
    get_acoustic_deployments(credentials = "not_a_credentials"),
    "Not a credentials object to database."
  )
})
