(category will default to nursery if not provided). This command will create
two files: `tests/ui/foo_functions.rs` and `clippy_lints/src/foo_functions.rs`,
as well as run `cargo dev update_lints` to register the new lint. For cargo lints,
-two project hierarchies (fail/pass) will be created under `tests/ui-cargo`.
+two project hierarchies (fail/pass) will be created by default under `tests/ui-cargo`.
Next, we'll open up these files and add our lint!
### Cargo lints
For cargo lints, the process of testing differs in that we are interested in
-the contents of the `Cargo.toml` files. If our new lint is named e.g. `foo_categories`,
-after running `cargo dev new_lint` we will find two new manifest files:
+the `Cargo.toml` manifest file. We also need a minimal crate associated
+with that manifest.
+
+If our new lint is named e.g. `foo_categories`, after running `cargo dev new_lint`
+we will find by default two new crates, each with its manifest file:
* `tests/ui-cargo/foo_categories/fail/Cargo.toml`: this file should cause the new lint to raise an error.
* `tests/ui-cargo/foo_categories/pass/Cargo.toml`: this file should not trigger the lint.
+If you need more cases, you can copy one of those crates (under `foo_categories`) and rename it.
+
The process of generating the `.stderr` file is the same, and prepending the `TESTNAME`
variable to `cargo uitest` works too, but the script to update the references
is in another path: `tests/ui-cargo/update-all-references.sh`.
