fix(ci): run integration tests when a binary they launch changes - #4131
Merged
Conversation
DAG test scoping runs the tests of changed crates and of crates that depend on them in cargo metadata. `integration` launches `iggy-server`, `iggy-connectors`, `iggy-mcp` and `iggy-bench` through `Command::cargo_bin`, an edge cargo cannot see. A PR that changed only `server`, `shard`, `partitions`, `metadata`, the connectors runtime, MCP or bench ran no integration test before merge. When one of those packages is affected, the step now adds `integration` to the test scope. The DAG selects the binary package for any change to a crate it links, so this also covers crates such as `partitions`.
