Eunomia 2.0 Unit Test Notes

[anthonysena]

Just making an issue here to note any changes made while attempting to update unit tests to use Eunomia 2.0 (currently on the develop branch).

1. Unit tests will need to set up the EUNOMIA_DATA_FOLDER environment variable so GitHub Actions (GHA) has a place to store the data. Here is some boiler plate code that could go into the tests/testthat/setup.R file for reference:

dataFolder <- tempfile()
dir.create(dataFolder)
oldEunomiaFolder <- Sys.getenv("EUNOMIA_DATA_FOLDER")
Sys.setenv("EUNOMIA_DATA_FOLDER" = dataFolder)
withr::defer(
  {
    unlink(dataFolder)
    Sys.setenv("EUNOMIA_DATA_FOLDER" = oldEunomiaFolder)
  },
  testthat::teardown_env()
)

2. Vignettes that use Eunomia will also need to set the EUNOMIA_DATA_FOLDER environment variable in order for the R CMD check to work properly on GHA.

3. The signature of the function Eunomia::getConnectionDetails() has changed. v1.x supported the following signature:

getEunomiaConnectionDetails <- function(databaseFile = tempfile(fileext = ".sqlite"))

v2.x removes the databaseFile parameter when calling Eunomia::getConnectionDetails(). The control over the databaseFile parameter is governed by the EUNOMIA_DATA_FOLDER environment variable. Alternatively, you can make use of the Eunomia::getConnectionDetails function for more fine-grained control over the dataset used, etc.
