| # Tests |
| |
| To run all tests, run the following command: |
| |
| ```sh |
| cargo +nightly test --all |
| ``` |
| |
| ## UI tests (`ui`, `compiletest.rs`) |
| |
| This checks errors detected by the macro or the Rust compiler in the resulting |
| expanded code. |
| |
| To run this test, run the following command: |
| |
| ```sh |
| cargo +nightly test --test compiletest |
| ``` |
| |
| Locally, this test updates the files in the `ui` directory if there are |
| changes to the generated code. If there are any changes to the files in the |
| `ui` directory after running the test, please commit them. |
| |
| See also [`trybuild` documentation](https://docs.rs/trybuild). |
| |
| ## Expansion tests (`expand`, `expandtest.rs`) |
| |
| Similar to ui tests, but instead of checking the compiler output, this checks |
| the code generated by macros. |
| |
| See [examples](../examples/README.md) for descriptions of what the generated |
| code does, and why it needs to be generated. |
| |
| To run this test, run the following command: |
| |
| ```sh |
| cargo +nightly test --test expandtest |
| ``` |
| |
| Locally, this test updates the files in the `expand` directory if there are |
| changes to the generated code. If there are any changes to the files in the |
| `expand` directory after running the test, please commit them. |
| |
| See also [`macrotest` documentation](https://docs.rs/macrotest). |
