# Test data for `cargo_embargo`
The files here are used for `cargo_embargo` integration tests. Run the tests with
```shell
atest --host cargo_embargo.test
```
## Handling changes in Cargo output
When the output of `cargo metadata` changes, you need to update the
`cargo.metadata` files found in the subdirectories here. Do this with:
```
for crate in aho-corasick async-trait either plotters rustc-demangle-capi; do
pushd $ANDROID_BUILD_TOP/external/rust/crates/$crate
cargo metadata --format-version 1 | jq --sort-keys \
> $ANDROID_BUILD_TOP/development/tools/cargo_embargo/testdata/$crate/cargo.metadata
popd
done
```
Run the integration tests again after updating the crate metadata.
Some tests will likely fail because of outdated information in the other test
files:
- `expected_Android.bp`: Adjust the version numbers to match the current version
from `cargo.metadata`.
- `crates.json`: Adjust version numbers and `package_dir` as necessary.
- `cargo_embargo.json`: Adjust the list of Cargo features if this has changed
since the file was last touched.
