ringabout 80e6b35721 templates/macros use no expected types when return types are specified (#24298)
fixes #24296 
fixes #24295

Templates use `expectedType` for type inference. It's justified that
when templates don't have an actual return type, i.e., `untyped` etc.

When the return type of templates is specified, we should not infer the
type

```nim
template g(): string = ""

let c: cstring = g()
```
In this example, it is not reasonable to annotate the templates
expression with the `cstring` type before the `fitNode` check with its
specified return type.

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.
