fixes#17571
Objects in the VM are represented as object constructor nodes that
contain every single field, including ones in different case branches.
This is so that every field has a unique invariant index in the object
constructor that can be written to and read from. However when
converting this node back into semantic code, fields from inactive case
branches can remain in the constructor which causes bad codegen,
generating assignments to fields from other case branches.
To fix this, fields from inactive branches are now detected in
`semmacrosanity.annotateType` (called in `fixupTypeAfterEval`) and
marked to prevent the codegen of their assignments. In #24441 these
fields were excluded from the resulting node, but this causes issues
when the node is directly supposed to go back into the VM, for example
as `const` values. I don't know if this is the only case where this
happens, so I wasn't sure about how to keep that implementation working.
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.
