[Feature]: Support test sharding (same as jest --shard=1/10) #887
Description
What problem does this feature solve?
One of the features that blocks us from considering Rstest as a PoC in our setup is sharding. Right now, we run our tests on 6 shards on CI.
Taking into account that we already use swc to parse test spec files and the fact that the codebase is growing, I do not expect having a single shard to be enough in our setup.
Do you plan to work on this? any high level estimations when this could potentially land in Rspack will be appreciated 👋🏿
