@runtest

Actions that run tests are attached to this alias. For example this convention is used by the (test) stanza.

Building @runtest directly uses normal alias target semantics. In a workspace with multiple contexts, an unqualified alias target is built in every configured context.

The dune runtest command, also available as dune test, has different command-line behavior: it accepts test path arguments and selects a build context for source paths. See Running Tests for details.
