> [Introduced](https://github.com/catchorg/Catch2/pull/2257) in Catch2 3.0.1.
When `--shard-count <#number of shards>` is used, the tests to execute will be split evenly in to the given number of sets,
identified by indicies starting at 0. The tests in the set given by `--shard-index <#shard index to run>` will be executed.
The default shard count is `1`, and the default index to run is `0`. It is an error to specify a shard index greater than
the number of shards.

Sharding is useful when you want to split test execution across multiple
processes, as is done with the [Bazel test sharding](https://docs.bazel.build/versions/main/test-encyclopedia.html#test-sharding).
