ringabout 197633dc8b fixes empty tag for nim ic (#25615)
`writeNode` writes `(empty flags type (empty))`, but it should have been
`(empty flags type)` instead

```nim
type
  Meters = distinct float
  Feet = distinct float

converter toMeters(f: Feet): Meters =
  Meters(float(f) * 0.3048)

proc showMeters(m: Meters) =
  echo float(m)

showMeters(Feet(10.0))
```
gives `[NIF decoder] expected: {ParRi} but got:
ParLe14,152,/Users/blue/.choosenim/toolchains/nim-\23devel/lib/std/private/dragonbox.nim(empty)`

This directory contains the test cases.

Each test must have a filename of the form: t*.nim

Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore top-level tests like tests/tbar.nim.

Specs

Each test can contain a spec in a discard """ ... """ block.

Check out the parseSpec procedure in the specs module for a full and reliable reference

action

Specifies what action this test should take.

Default: run

Options:

  • compile - compiles the module and fails the test if compilations fails.
  • run - compiles and runs the module, fails the test if compilation or execution of test code fails.
  • reject - compiles the module and fails the test if compilation succeeds.

There are certain spec keys that imply run, including output and outputsub.

Categories

Each folder under this directory represents a test category, which can be tested by running koch tests pcat <category> (or cat to avoid parallel testing, which is slower).

The folder dll contains simple DLL tests.

The folder realtimeGC contains a test for validating that the realtime GC can run properly without linking against the nimrtl.dll/so.
