### Database tests with fixture setup

Source: https://docs.rs/libloot/latest/src/libloot/database/mod.rs.html

```rust
#[cfg(test)]

### Build groups graph with BU groups and start PluginsGraph

Source: https://docs.rs/libloot/latest/src/libloot/sorting/plugins.rs.html

Builds a groups graph with two sets of groups (including a default group and BU1/BU2 groups) and starts constructing a PluginsGraph with plugins A, B, and B1. The snippet is truncated at the point where the graph is being populated; the test name indicates it verifies that nodes are marked unfinishable if a node in their subtree is unfinishable.

```rust
let fixture = Fixture::with_plugins(&[
    PLUGIN_A, PLUGIN_B, PLUGIN_B1, PLUGIN_B2, PLUGIN_C, PLUGIN_D,
]);

let groups_graph = build_groups_graph(
    &[
        Group::new("A".into()),
        Group::new("B".into()).with_after_groups(vec!["A".into()]),
        Group::new("C".into()).with_after_groups(vec!["B".into()]),
        Group::new("D".into()).with_after_groups(vec!["C".into()]),
        Group::default(),
    ],
    &[
        Group::new("BU1".into()).with_after_groups(vec!["B".into()]),
        Group::new("BU2".into()).with_after_groups(vec!["BU1".into()]),
        Group::new("C".into()).with_after_groups(vec!["BU2".into()]),
    ],
)
.unwrap();

let mut graph = PluginsGraph::<TestPlugin>::new();
let a = graph.add_node(fixture.group_sorting_data(PLUGIN_A, "A"));
let b = graph.add_node(fixture.group_sorting_data(PLUGIN_B, "B"));
let b1 = graph.add_node(fixture.group_sorting_data(PLUGIN_B1, "BU1"));
```

### Get Windows file information

Source: https://docs.rs/libloot/latest/src/libloot/archive/find.rs.html

Opens a file and retrieves its BY_HANDLE_FILE_INFORMATION using the Windows API GetFileInformationByHandle. Returns None if the file cannot be opened or the call fails. The unsafe block is justified because there is no safe alternative for this data.

```rust
#[cfg(windows)]
fn get_file_info(file_path: &Path) -> Option<BY_HANDLE_FILE_INFORMATION> {
    use std::os::windows::io::AsRawHandle;
    use windows_sys::Win32::Storage::FileSystem::GetFileInformationByHandle;

    let Ok(file) = std::fs::File::open(file_path) else {
        return None;
    };

    let mut info = BY_HANDLE_FILE_INFORMATION::default();

    #[expect(
        unsafe_code,
        reason = "There is currently no way to get this data safely"
    )]
    // SAFETY: This is safe because the file handles and the info struct pointers are all valid until this function exits.
    let result = unsafe { GetFileInformationByHandle(file.as_raw_handle(), &raw mut info) };

    (result != 0).then_some(info)
}
```

--------------------------------

let expected_result = "prelude:
  globals:
    - type: note
      content: A message.

plugins:
  - name: a.esp
";

assert_eq!(expected_result, result.masterlist);

let fixture =
    Fixture::with_plugins(&[PLUGIN_A, PLUGIN_B, PLUGIN_B1, PLUGIN_B2, PLUGIN_C, PLUGIN_D]);

let output_path = fixture.inner.local_path.join("minimal.yaml");

database.load_masterlist(&fixture.metadata_path).unwrap();
