This fails to get the shinytest2 test to run (unless unstats is installed) because are references to unstats::un_data in the app code. Any references to the package-under-development can be problematic, because the R session where the app runs must have access to the package itself.
Note that pkgload is added to Suggests rather than Imports. golem::add_rstudioconnect_file() adds pkgload to Imports, which throws a 'note' in R CMD check (because the package doesn't actually use it).
This circumvents problems with loading the dev version of the package into the session where the app runs during tests, because it uses pkgload::load_all() in the app.R file.
…MD check But always remember to 'install' your package before using devtools::test()

Uses a module-specific app, into which data/reactives can be passed, to demonstrate that shinytest2 can be used to test components.
This example is a bit pointless, the same idea can be tested using testServer, and the workshop attendees do this in the subsequent exercise.
