Following is some information you might find useful regarding the particularities of contributing to `diskonaut`:

### Testing
Diskonaut uses automated integration tests to make sure everything is working as it should.
If you're adding new functionality, you might want to add new tests or adjust the existing ones.

These tests work by creating textual "snapshots" of how the UI looks in certain situations. One test can have several snapshots.

An example test would be:
1. Create a temporary folder with a few files and subfolders.
2. Run diskonaut on that folder and take a snapshot of its UI. Make sure that snapshot is identical to the snapshot stored in this repository for that test.
3. Enter one of the subfolders, take another snapshot and make sure it is identical to the second stored snapshot for that test.

To store and compare the snapshots, we use [`insta`](https://docs.rs/insta/0.8.1/insta/)

For an improved experience, you can install `cargo-insta` on your computer, which will allow you to review new snapshots - approving or rejecting them. Please see the insta documentation for more details.

### Code formatting
`diskonaut` uses [rustfmt](https://github.com/rust-lang/rustfmt) for code formatting. In most (all?) cases, if you have it installed on your computer, you can run `cargo fmt` in the project folder, and it will auto fix your code.
