Nested Describe Functions Fail

[FlippieCoetser]

According to Testhat Documentation, nesting describe() functions should be possible: link

Below is a copy of the example in the documentation

# Nested specs:
## code
addition <- function(a, b) a + b
division <- function(a, b) a / b

## specs
describe("math library", {
  describe("addition()", {
    it("can add two numbers", {
      expect_equal(1 + 1, addition(1, 1))
    })
  })
  describe("division()", {
    it("can divide two numbers", {
      expect_equal(10 / 2, division(10, 2))
    })
    it("can handle division by 0") #not yet implemented
  })
})

However, when trying to run the example in VS code, an error is thrown:

Removing the nesting like so:

## specs
describe("math library", { 
  it("can add two numbers", {
    expect_equal(1 + 1, addition(1, 1))
  })
  it("can divide two numbers", {
    expect_equal(10 / 2, division(10, 2))
  })
  it("can handle division by 0") #not yet implemented
})

Works as expected.

Oof, finally someone stumbled upon some edge case of my hack of running tests by themselves 😅 Thanks for the issue, although, note that testthat has file atomicity, so anything finer than that might not be trustworthy. I will check this out at some point, but no promises.
