# Tests
Many of the tests in this repository are based on [pin-project's tests](https://github.com/taiki-e/pin-project/tree/HEAD/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.
## Expansion tests (`expand`, `expandtest.rs`)
Similar to ui tests, but instead of checking the compiler output, this checks
the code generated by macros.
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.
