2. `cargo test --package ra_ide --lib -- hover::tests::test_hover_enum_has_impl_action --exact --nocapture` **`-- hover::tests::test_hover_enum_has_impl_action --exact --nocapture`**
3. `cargo test --package ra_ide --lib -- hover::tests::test_hover_enum_has_impl_action --exact --nocapture` **`-- hover::tests::test_hover_enum_has_impl_action --exact --nocapture -- hover::tests::test_hover_enum_has_impl_action --exact --nocapture`**
