Encapsulate `testServer()` in `test_that()` for module unit tests

[statnmap]

Add test_that("mod works", {}) around here, so that tests are recognized as is by {testthat}

golem/R/modules_fn.R

Line 275 in b62587c

write_there("testServer(")

As far as I can tell, this is not required:

• 5 tests in the test file, 5 in the {testthat} output
• 100% code coverage

This might have some corner cases for when you need the tests to be inside a context.

I'm putting this on hold for now until further exploration can be done

I'm closing it, as far as I can tell there is no need to wrap things around test_that for the test to work or be detected, and the shiny doc uses this structure (without test_that)
